Measurement Computing Corp. (MCC) has launched its third DAQ HAT for the Raspberry Pi, this time taking on temperature measurement. The $149 MCC 134 Thermocouple Measurement HAT follows its MCC 118 voltage measurement DAQ HAT with eight ±10 V inputs and sample rates up to 100 kS/s and its MCC 152 voltage output and digital I/O HAT with dual 0-5 V analog outputs at up to 5 kS/s and 8x configurable DIO.

The MCC 134 also offers open thermocouple detection so users can monitor for broken or disconnected thermocouples. Each channel type is selectable on a per-channel basis. The board provides a HAT-compatible 40-pin GPIO for easy installation. Other features include a 24-bit A/D converter, 3x cold-junction compensation (CJC) sensors, and linearization features.
