This sensor measures water vapour content relative to the ambient temperature and is useful for Environmental and Biology studies. For example, a simple transpiration experiment can be set up and the results analysed in less than 5 minutes.

Applications

Biology:

• Water vapour expelled through the skin and breath*
• Transpiration of plants*

Environmental Science:

• Weather studies
• Determining dew point*

*See the Five Minute Activities book for examples.

This sensor is designed for monitoring relative humidity.

The slots in the end cap allow for circulation of air to maximise response times.
