M5Stack KMeterISO Unit with Thermocouple Temperature Sensor

The KMeterISO Unit is a temperature sensor with an I2C communication interface, utilizing an STM32F030 main control chip and a MAX31855KASA+T 14-bit thermocouple digital converter chip. This temperature sensor is specifically designed for K-type thermocouples and supports thermocouple probes with a measurement range from -200°C to 1350°C. The temperature sensor features an I2C communication interface and an STM32F030 chip that supports an I2C firmware update. This temperature sensor is ideal for industrial temperature detection and situations requiring constant temperature control/monitoring.
