Product description: Dual Kmeter 13.2 MAX31855 - two-channel temperature measurement module - for K-type thermocouples - M5Stack M127
The Dual Kmeter 13.2 module from M5Stack is a two-channel module for temperature measurement using K-type thermocouples. It is based on the MAX31855KASA+ technology and is integrated with the STM32F030F4P6 microcontroller, it also offers galvanic isolation. The measurement range is from -200°C to 1350°C and the measurement accuracy is ±2°C . Additionally, the DualKmeter module has built-in voltage and signal isolation systems, such as B0505LS-1WR2 and CA-IS3020S , which ensure system stability and security. It is possible to change the address of the I2C interface, which allows for quick adaptation of the sensor depending on needs. It can be used in many applications such as industrial automation and instrument detection.
