Controlling a Relay using Temperature (Temperature Controlled Relay with Thermocouple, Arduino, LCD)
Mish Mash Labs demonstrate how to control a high voltage (230V AC) Relay using a temperature value set-point. The temperature value is read from a K-Type Thermocouple, which is interfaced using a MAX31855 breakout board over SPI to an Arduino. The measured temperature values are displayed on an LCD.
In our example, the temperature controlled relay is switched ON, by the Arduino , once the temperature reaches 40 degrees C, and OFF if its below. This value can be adjusted to suit you. The light bulb can be swapped with a heating element.

We used the Arduino Uno, but this will work with all Arduinos, even clones.
