Thermocouple HAT Adds Temperature Measurement To Low-Cost Computer

Measurement Computing’s MCC 134 thermocouple measurement HAT is designed for use with the Raspberry Pi. Essentially, the MCC 134 brings high-quality, temperature measurement capability to the popular low-cost Raspberry Pi computer.

Featuring a 24-bit resolution, the HAT provides four thermocouple (TC) inputs capable of measuring the most popular TC types including J, K, R, S, T, N, E, and B. Each channel type is selectable on a per-channel basis. Open thermocouple detection lets users easily find broken or disconnected thermocouples.

Up to eight MCC HATs can be stacked onto one Raspberry Pi. With the already available MCC 118, eight channel voltage measurement HAT and the MCC 152 voltage output and digital I/O HAT, users can configure multifunction, Pi-based solutions with analog input, output, and digital I/O.
