Temperature Sensor Heater with Solid State Relay

[tanders82]

Excellent video!

[MrAJ2500]

Something also worth considering- Crydom has releases a temperature-control solid state relay that has the logic built in and takes a type J or K thermocouple input. It's their MCTC series... No wonder they have 60%+ of the solid state relay market share in the USA.

hello this good

can u give the diagram

i am makeing an incubater so i need this

if u can pleas send to vikaspoikara@yahoo.com

thankyou

[shakirkohatian]

i mean the diagram and some details ,,, if you can

[shakirkohatian]

its a very very nice project ,,, i wish if you could send me the circuit ,,, and thing in more detail ,,, on my email shakirkhan.niazi@hotmaill.com ,,, please

[localbroadcast]

Lol I was in yur class patrick.  I posted a vid of a temp sensing circuit I made. Check it out if you like.

[robot797]

do you have a circut?

[PeaceAndJustice357]

That's nice

[thebigdash]

This is awsome! What did you use for your tepature sensor?

[davidvro]

I've done that for my cooler with a High Precision Humidity Sensor SHT15 and a Netburner (freescale) MCU

[firealarmfreak]

so could i use a tempeature sensor to make a homemade heat detector for my homemade fire alarm panel? and program it so when the temperature gets to a certain temp, it activates my circuit?

[patrickikis]

No programming required. Calibration is a better word for it. There's a little math involved, but yeah. My only concern would be that most fire alarms do not detect heat, but smoke.

[CaaBal]

NEEEEEEEEEEEEEEEEEERDS!!!!

[vish12]

dude u know ur circuit did u use a 741 opamp and if u did how did u connet it up coz myn switches only wehen it wants to .i.e if i put ice on the thermostat it triggers my 555 timer only sometimes :S i dunno whts wrong with it....plz could you tell me how u connected yours...thanks :D

[patrickikis]

If you can be more specific as to how you've set up your circuit, maybe I can help. You're getting intermittent results. Perhaps it is a decoupling error. Have you decoupled your circuit properly? Is anything shorting?

[vish12]

ohh nnoo crap i dont think ive decoupled it ..is that by using a capacitor to store charge or something because ive not studyied decoupling a circuit before thats why. and no i dont think ive got a shorting problem

[Da0m4r]

this stuff is a life saver...dude can u please send me the circuit diagram :D

[thatstrangerman]

you could really sell that you know? an automatic cold-sensing heater? that'd be great anywhere.

[patrickikis]

Dude, you are my hero.

We had the option of specializing in analog or digital electronics. I am a hardware kind of guy, which sucks because ass we do is program in assembly code. It really sucks!

Most of my newer videos will suround programming. I've got a CPLD programming video, and some C programming to mess with the parallel port of my computer.

Thanks for commenting.

[Jimmypage512]

lol funny dude..

what was that writting on your hand lol

Yeah I keep a portfolio of my circuits too.. trust me though.. employers dont give a crap about them.. hardware jobs are no where these days. all software.. sigh i hate software ..

[vish12]

and also have u used a 555 timer as a trigger?

and if you have is it monostable?

[patrickikis]

??? I use 555 timers every day. I wouldn't implement a 555 timer in this circuit for either astable or momostable operations. If you are suggesting using the output of a 555 timer to trigger the solid state relay, it can be done with ease. I don't really understand your question. Yes, it is NTC.

[vish12]

cheers for the reply..soz if u couldn't understand my question my bad...but i got my answer :D... one thing though did u se a 555 timer in this circuit coz it looks like u have?

[patrickikis]

Naw, there is no need for any monostable or astable operations in this circuit. No need for a clock.

[vish12]

i am making a similar system for my electronics project...is your thermistor a ntc type?
