DualKmeter Module 13.2 (MAX31855)

The DualKmeter module 13.2 is a dual-channel K-type temperature measurement module based on the MAX31855KASA. The module has a built-in two-way K-type thermocouple sensor interface, which uses the signal relay to measure the temperature value of the two channels in turn, supporting a measurement range of -200°C to 1350°C, and a measurement accuracy of ±2°C. At the same time, the module also has built-in voltage and signal isolation chips such as the B0505LS-1WR2 and CA-IS3020S, ensuring the stability and safety of the system. In addition, the module has a built-in dial code, which can easily switch different I2C addresses. It can be applied to multiple scenarios such as industrial automation and instrument detection.
