M5Stack Kmeter Unit with Thermocouple Temperature Sensor

This is an M5Stack Kmeter Unit module with a nickel-chromium (type-K) temperature sensor. The Kmeter Unit is controlled by an ESP32-C3 and features a MAX31855KASA+T 14-bit digital thermocouple conversion chip. The included type-K temperature sensor has a measurement range from -50°C to +250°C with a tolerance of ±2%. The module communicates through the I2C interface and has a HY2.0-4P connector.
