Product information "Pmod HYGRO: Digital Humidity and Temperature Sensor"

Flexible peripheral modules for all your designs

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.

Overview Pmod HYGRO

The Pmod HYGRO is a relative humidity sensor with integrated temperature sensor for highly accurate measurements at low power. With the TI HDC1080, you can determine the relative humidity of the environment with up to 14 bits of resolution. The Pmod HYGRO is designed to digitally report the relative humidity and ambient temperature upon request by the host board. Up to 14 bits of resolution for each sensor may be collected by allowing for longer conversion times. A resistive heating element can be enabled to test the sensor or to drive off condensation that accumulates on the sensor after being consistently exposed to high humidity conditions.
