 alright hello guys I just wanted to talk about this little kit I bought it's another ebay jobby and the description name for this is the human sensor module pyroelectric infrared PIR DIY kit this is quite expensive actually this is a £3.88 for this and what it does is it will take a 4.5 to 5 volt input to work the circuit and when it senses it says human because it works off heat rather than just movement as a lot of the old systems were just just movement you know so if a tree was blowing a branch around a bit it would pick up and start the record or trigger an alarm where these ones are it works out of the heat so I figured it'd be quite good I'm gonna connect it on to another little circuit possibly to have a light downstairs from the how many got terrible things up so yeah so what we're gonna do now is we're gonna put it together and see if it works so if we look inside now I'm not I'm not a great review or anything like that I'm just an enthusiast in electronics found myself with a bit of time and what can I do if I can get my head into something and let's see what we can do with it let's make sure we got all there's quite a few pieces there back now this you're gonna be careful where put the fingers so I understand that these actual sensor modules I'm gonna look see if it's broken or not and it doesn't appear to be that's good I understand these little sensor modules are quite sensitive to oils but there it is that's that's the actual sensor and we don't want to touch it as we don't leave any grease or oils from my skin on it but everything else of course is it's perfectly fine so we got we got some little parts here for adjustments I'm not quite sure what the value of those are this is 105 105 it's one over five zeros that's that one meg possibly what we got here that's 8050 not quite sure what that is some sort of little transistor maybe a regulator I could look it up 16 volt 100 mic cap 25 volt 22 mic cap we got a BISS 00001 16 pin IC and the socket Sean Heder is the relay this is a 5 volt activated relay to switch 250 volts up to 3 amp oh I can actually switch that's AC 254 or 3 amp 30 volt DC oh so that's quite good then so that's a seal DC only 3 amp on DC so not a great thing there and just a little little correction of little ceramic capacitors and whatnot so I think I'm probably gonna go into full steam ahead to put this together I'm just wondering how well how this board goes I can't see anything obviously very obvious for how it goes but I can see quite quickly how this main main part is gonna go together and hopefully this is not gonna take too long of course that won't be the first thing I put on I'm gonna put all the little all the little tiny bits on first so we're not working on our own way and the actual last so so I'm gonna speed this up I'm gonna very very well laid out board I should expect to find one of these now that come through you don't really need any great you know because it says it says 1.8 K sorry 18 K 10 K 47 K 18 K 18 K so everything's on there let's know that you get up on to put on to you variable resistors one and two I should sort of I should probably carry on with the it says suit type PYM-1 not quite sure that means but the working voltage four to five four point five to five volts it's got a standby current of 65 microamps a working current of 40 milliamps the low power less than or equal to 300 watts it's blocking time is two and a half two and a half seconds to 300 seconds 300 seconds five trigger L not repeatable trigger H a repeatable triggered not quite sure what that means but sensing range cone angle is less than 120 degrees can be adjusted within five meters working temperature minus 15 C to plus 70 C and that's that's pretty much it just tells you the size of the board which is 27 by 27 millimeters even though that doesn't actually have a synthesized 27 by 27 millimeters blah blah and and this control PCB is 40 by 60 there's just one thing that's worth noting on this is that it's off you get the same none of the none of these none of these are marked so you're gonna need a meter or unless you can read the color codes to know what they are you will need a meter yeah so let's put it together okay it looks like these babies they go underneath here so this can be you know flitted to something well it's just let's just soldered this on first I'm gonna do that I'm thinking about using a new real assault only sometimes I'm gonna be supposed to or not doesn't feel like it wants to so it's just soldering the way it is stand this up to solder it oh it stands up like so problem is where I'm doing the soldering now is I've got two two sides I don't have to run this when you've got them bridged over like that uses ways that I found is literally just get the fattest bit is sold in line and just run it through pull it back and it collects on there and takes it away from there so apart from putting this little baby on and I'm not sure if there's a natural way to fit this I'm gonna go on what looks to be those two go together and that doesn't because on the back of here you got two little black dots I don't know if you can see those at all yep and then you got two sort of next to each other here and then the one coming off so I'm gonna assume that that's how that goes on I'm probably wrong to assume this if I were to do it the other way it wouldn't it doesn't seem like it so I'm gonna put them on like that I'm being very careful not to touch the front and I'm just gonna do a quick check I don't see the point of solving it because I can just quick check what I need to do that here I'm just trying to see actually no I can't actually see any type of instruction for doing that so well here the sensor then is like sideways on the front here but I'm not touching the front of it I'm not touching the lens part I'm just touching on the outside if I were to put it any other way it just wouldn't I put those like that that seems to be the only way it can go yeah it's got to be that way that seems to be the only way it can go the way those legs are set and it just stands the reason there's two up it's almost indicated that that's the way so I'm gonna take the chance on that as it just doesn't seem like it goes the other way just drop a blob of soldering that's nice and flat slightly off I'm trying to push it flat without getting any oils okay that looks like it's in flux we can just solder that now and there's bits in I wouldn't leave you soldering on too long on these pads on this especially if you've got it really hot there's some awful awful awful stuff coming off my solder I don't know if you can see that I think it's because when you get a new reel they they seem to put tape around it yeah which is a bit backwards really because that leaves bits of tape all over your solder and you end up you know melting the glue and such that's on the tape while you're doing your soldering which is something I will comment to the I can't tell what language that is but it's it's got more continents than it has vowel continents at constant constants I hope I've said that right now but it seems like a lot more of those they deserve also let's pull it off and hope that this game between these pins is not going to be conductive so we can use a little bit of alcohol on here and it doesn't cause any problems but the last thing we wanted to do is a conduction between nose nice clean up with some alcohol well we'll certainly help prevent that so okay we seem to have just a couple of bits on the lens I'm just brushing my fingers across the bristles of the brush the toothbrush and I'll just wipe those off without you know me I've probably damaged it man just mind not just wipe away the grind there put this on just we can get that front part being protected okay you'll be quite gentle you don't want to break you don't break that so so that looks like that's how it's supposed to be I've tinned a bit thicker these lines going here which go from the relay to the at the switchable output I just put these on and speed this process up so there we go that's that bill of course the proof is in the pudding does it actually work I'm sure the kit works I should say have I actually built it correctly so it will work now we need to apply five volts here and then put a load on here and then play around with this here so I'm quite disappointed with myself because I did have a load but then I give it its own plug so I need to find something else to put on this that doesn't draw more than 300 watts okay I can find something and I will I shall come back and we will see if that works okay I found something looks a little bit offish not just been cutting garlic and stuff see if you see things in my hand it's gonna making my food and one is that this actual this fitting socket you gotta put it in backwards for in order for this to fit into it this has to go in backwards which is in contrary to the image shown on the website when you buy this on the actual picture and there's another thing I know this as well it looks like there's a light dependent resistor is supposed to go in that those holes there this is not supplied is not in the image and it's not detailed in the description as for I've been part of this circuit but what I will do is I'm gonna get this running as it is and then I'm gonna put a light dependent resistor in there and see if we have any control over the light situation so whether it only operates at nighttime or it operates during the day but we're gonna figure that out we're gonna figure that out because as you can see the pads are there clearly for it I can't see anywhere else it goes to the chip via the resistors and yeah and also via this so I do have a feeling that if we put one in there we might get a little bit extra functional tell this baby but first of all let's just chuck some five some five volts onto it and see if we just get really triggering now I've taken apart my light which I did fit with a and so what we've got is this connection here and I'm gonna use these two wires in order to connect this thing into bomb and hopefully it will trigger the light that I have here now it's a bit we're a bit tight for the wire I've got to pull it through the back of my bench this was a lot better taped up believe me it was quite safe right so let's just check my bolts into that okay well that's a little lights come on and I did hear the relay click now whether the relays just clicked on because it doesn't know what else to do it's got a little screwdriver and play with these I turn that all the way down or at least it gives the impression of the old way down I want to hear the relay click I turn it back off again there we go so the relay clicks back off again a little light is not on and if I put my hand oh that was quite nice I didn't quite get near it and I was out you know quite a way out here really and so that is actually switching I've set it down to the minimal I'm gonna try and just come in across the top of it now you can see my finger so I'm on I'm over the top of it and that's that's picking up quite good I was picking up quite well and now we want it to switch this lamp on I'm just gonna turn that off just what I can it doesn't pull out there flip my lights on watch your eyes right so we've got a normally closed on and common so I would think then that we want I put something in there that will indicate to me when I've actually got a circuit across that and it won't bloody lifting up he says so if I put my continuity test I said somebody stopped me I'm doing this wrong but really that's not gonna be possible is it so if I just chuck that in there chuck that in there and all I want is a little bit of continuity if this circuit works as I think it should so I flip well we've not got any continuity so again continuity like that okay so I've got a lot of points hopefully that will go off as soon as I say it goes off yes so that's what we want to be then isn't it yep so we can shut that off now we know we want to plug our avayas into just gonna chuck a wiring there let me open this up first because all it is is technically it's just a switch isn't it just an electronic switch so which is fantastic because I will use this in here I will actually use it for this lamp I'll put it onto its its extended time five minutes or you know somewhere between four seconds or whatever it is in five minutes and see how I can live with this in here so when I do leave the room I know it's just a gimmick because really I've got a two and a half watt bulb in this and it's not really gonna make much of a difference to my build I just want to play around with it so that's on this is on and I'm just gonna switch off no no plug the plug-in and and switch the and switch that one well that lamp's on so that's gone off now I'm gonna plug the plug in ready for the big bang okay so that lights on that's the lamp shining now and now it's gone beautiful there's no smoke there's no sparks there's me moved that's what made that happen I quite like that so now because I need it about this far I suppose the distance is okay I mean that's it that's a small load it says up to 300 watts as I say I haven't actually got a we don't seem to be registering that easy from the front so now I must mind that this is live now 240 volts we're gonna switch that off there of course nothing's gonna happen but I am students you know that I've still got to right so we got min max on the time and we got min max I believe that would be sensitivity so that's too big to be turning that would be nice to have an insulated screwdriver I need to buy myself a little set of screwdrivers don't really have one of these so I'm gonna keep the time down just for a minute so we can adjust this so the min there I'm not sure whether that's for how sensitive this is gonna be I'm gonna switch it back on again so everything's gonna come on straight away that's it's not the greatest of lights I understand okay so the sensitivity now this thing is so low that we're not actually getting anything out of it I think that's possible okay we do but it seems to be sensitive to what's going above it or even though that's not really doing a great deal is it okay so if I turn that back down to max sensitivity I believe this is but yeah so if you've got this far guys thank you very much for watching and this seems to be another another winner our feet mate
