The Humidity sensor ML48m measures relative humidity and temperature.
 Two sensing elements are placed inside the sensor box. The slots in the end cap of the sensor allow air circulation.

**Technical specifications:**

- Range: 0 .. 100% RH, -20 .. 50 °C
- Maximum sampling rate: Humidity 20 Hz, Temperature: 4 Hz
- Resolution: 0.4 % RH, 0.0625 °C

Can be used in experiments to:

- study transpiration rates of plants,
- optimize conditions in a greenhouse or terrarium
- determine good days for static electric
   demonstration.
