Relative Humidity

The Relative Humidity Sensor can be used to measure relative humidity in the air as part of a weather station, or to do any of the following:

  • Monitor indoor humidity for health reasons

  • Optimize conditions in a greenhouse or terrarium

  • Determine when static electrical discharges will be a problem

  • Study transpiration rates of plants by monitoring relative humidity in sealed jars containing plants


1. Connect the Relative Humidity Sensor to the LabQuest interface.

2. The interface will identify the Relative Humidity Sensor and load a default data collection setup.

3. You are now ready to collect data.
