M5Stack Unit Kmeter Thermocouple Temperature Sensor

M5Stack Unit Kmeter Thermocouple Temperature Sensor with I²C communication interface adopts ESP32-C3 main control and MAX31855KASA+T 14bit thermocouple digital conversion chip. The internal ESP32-C3 integrated firmware of the temperature sensor communicates with the thermocouple digital IC to process the raw data and expose the I²C interface. This MAX31855 temperature sensor is specially designed for K-type thermocouples and the conversion chip supports thermocouple probes with a measuring range of -200°C to 1350°C. The temperature sensor features an I²C communication interface and ESP32-C3 (support I²C firmware update). This max31855 temperature sensor is ideally used in industrial temperature collection and in a constant temperature control/monitoring scene.
