Relative Humidity Sensor

Relative Humidity Sensor product image

The Relative Humidity Sensor can be used for weather studies, monitoring greenhouses, or determining days when static electrical discharges could be a problem.

Description

The Relative Humidity Sensor contains an integrated circuit that can be used to monitor relative humidity over the range 0 to 95% (± 5%).

These units are designed to be used with one of the interfaces sold by Vernier and are not standalone sensors. If you are looking for a standalone relative humidity sensor, consider a sensor by Honeywell.
