Relative Humidity Sensor
The Relative Humidity Sensor can be used for weather studies, monitoring greenhouses, or determining days when static electrical discharges could be a problem.
The Relative Humidity Sensor contains an integrated circuit that monitors 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.
Range: 0% to 95%
Power: 200 µA @ 5 VDC
Response Time (time for a 90% change in reading):In still air: 60 minutes (typical)
With vigorous air movement: 40 seconds (typical)
Typical Resolution: 0.04% RH
