Product description: Kmeter Unit - temperature sensor with thermocouple - MAX31855 - Unit expansion module for M5Stack development modules
The Kmeter Isolation Unit is an integrated K-type thermocouple sensor that combines the functions of acquisition, isolation and communication. It uses the STM32F030 chip and the MAX31855KASA+T 14-bit digital thermocouple conversion chip for precise temperature measurement and conversion. The STM32F030-based MCU supports data acquisition and I2C communication interface. The CA-IS3641HW signal isolator is used for signal isolation. The device enables the use of thermocouple probes with a measurement range from -200°C to 1350°C , using a standard K-type interface. This module is used in temperature data collection, control and monitoring.
