Pmod HYGRO Digital Sensor

Digilent's Pmod HYGRO is a relative humidity sensor with integrated temperature sensor for highly accurate measurements at low power. With the TI HDC1080, the relative humidity of the environment can be determined 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.
