Thermostat Kit 0 - 100 C

Controls your device by switching on the relay when the warm temperature you desire is reached (for a fan/air conditioner), or when the low temperature is reached (heater), depending on the state of the two position switch. Or when the temperature varies 2 degrees from your high or low setting.

This is one of the simpliest temperature sensor configurations used today. 1 4 Op Amp  IC is used to buffer the signal and create a window comparator. The output drives a relay, or you could make a logic out to your micrcontroller. Plus its 12 VDC so you can use it in your car, or on your boat. While working or vacationing, the choice is up to you!

It can be set to detect the temperature from 0 TO 100 C.
Uses IC LM335Z for the temperature detector.
The temperature range can be adjusted be potentiometer.
Operating voltage : 12 VDC.
Current consumption about 50mA.
Recommended housing : FB04
PCB dimensions : 3.8" X 2.1"

While the relay may have a fairly high current rating, the traces and connections that are typical of this PCB would be rated around 4 amps max, any more then that use another relay to switch your load.

Or solder right to the bottom of the PCB where the leads come out of the relay. Small currents of 5 amps max should be expected from this configuration. However if you have any feedback let me know, I will pass it along. In the mean time. Keep your cool!...
