Product ID
BM42S3021-1
The product is a thermocouple module. Unlike related modules on the market that only support a single type of thermocouple, the product supports five types, including K-type, N-type, E-type, J-type, and R-type. The measurable temperature range varies depending on the connected thermocouple type. The temperature range of the common K-type thermocouple is -270°C to 1370°C. It is suitable for temperature monitoring in products such as industrial boilers, ovens, and water heaters.
The product has built in a 24-bit A/D converter Flash MCU, the BH66F5355. Upon powering on, the system will first read the values from the Modeconfig register to determine the type of thermocouple currently in use. It will then continuously perform measurements. You can also issue the command to enter sleep mode to reduce power consumption.
⬥ Refers to the “Communication interface” chapter in the datasheet for more information.
