Mikroe Thermostat 4 Click senses temperature of a physical system and performs actions so the system’s temperature is maintained at a set point. The board features the Texas Instruments TMP392 resistor programmable temperature switch. It enables the protection and detection of system thermal events from 30°C to 130°C. It offers dual overtemperature (hot and warm) detection. The trip temperature options are programmed by changing the trimmer resistance value for channel A. The digital potentiometer resistance value is programmed over SPI interface for channel B. The Thermostat 4 has a high-quality Omron relay, that is used to open or close an electric circuit. It can be used with voltage up to 30VDC/220AC and current up to 5A.
