This board is like a thermostat which works from 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. Runs on 12 V DC. Already assembled.

This item is only the board, no AC-DC adapter / wiring

Technical information:
- This circuit is a measurement of temperature.
- It has cut-off circuit when the lower or higher temperature varied 2˚C from your setting.
