Pmod TMP3: Temperature Sensor

Description

Pmod™ devices are Digilent’s line of small I/O interface boards that offer an ideal way to extend the capabilities of programmable logic and embedded control boards. They allow sensitive signal conditioning circuits and high-power drive circuits to be placed where they are most effective - near sensors and actuators.

Pmod modules communicate with system boards using 6, 8, or 12-pin connectors that can carry multiple digital control signals, including SPI and other serial protocols. Pmod modules allow for more effective designs by routing analog signals and power supplies only where they are needed, and away from digital controller boards.

The Pmod TMP3 is an ambient temperature sensor built around the Microchip TCN75A. Users may configure the output through I2C to up to 12 bits of resolution as well as setting a trigger to occur when a user defined temperature threshold is reached.
