The DualKmeter module13.2 is a dual-channel K-type temperature measurement module based on the MAX31855KASA+stm32f030f4p6+galvanic isolation. 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 B0505LS-1WR2 and CA-IS3020S, ensuring the ‘stability and safety’ of the system. In addition, the module has a built-in dial code on off, which can easily switch different I2C addresses to meet the different application needs of users. It can be applied to multiple scenarios such as industrial automation and instrument detection.
