The Thermostat 3 Click Board™ is a general-purpose thermostat Click Board™ designed to be used with any temperature sensor based on the MAX31855 sensor design. The Click Board™ is equipped with a 2-pin female socket for thermocouple connection.
The K-type thermocouple can be connected directly into the socket, allowing the MAX31855 to take care of the signal-conditioning and output the absolute temperature value. The Click Board™ also contains a high-quality relay from Omron, that can be used to open or close an electric circuit. Despite its small size, it can be used with voltage up to 30VDC/220AC and current up to 5A.
