Temperature Sensor Heater with Solid State Relay

A temperature sensor circuit calibrated to activate and deactivate a Schmitt trigger at 18-22 degrees; triggering the solid state relay at high logic, that is connected to a portable heater. And yeah, I was hung over, and I look awful...

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.

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?

[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.

Good one.

Can I use this sensor to detect boiling point of water (100 degC) and turn the electric boiler off?

I can pack the sensor and immerse the sensor in boiling water. What will I need?

Excellent video!

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
