M5Stack Kmeter Unit with Thermocouple Temperature Sensor (MAX31855)

UNIT Kmeter is a K-type thermocouple sensor with I2C communication interface. The hardware adopts ESP32-C3 main control + MAX31855KASA+T 14bit thermocouple digital conversion chip. The internal ESP32-C3 integrated firmware communicates with the thermocouple digital IC to process the raw data and expose the I2C interface. The user can easily obtain the processed temperature data. This product is specially designed for K-type thermocouples. The conversion chip supports thermocouple probes with a measuring range of -200°C to 1350°C, and adopts a general standard flat interface, which is convenient for subsequent replacement of different measurement probes with different ranges to match different needs. It is suitable for industrial temperature collection, monitoring and other scenes that have high requirements for temperature measurement range.
