TBSLWS1 SDI-12 Leaf Wetness Sensor

The TBSLWS1 leaf wetness sensor mimics the wetness state of a real leaf. The measurement value is proportional to the percentage of the sensor surface covered with water. The sensor is equipped with a SDI-12 interface for measurement and calibration.

In case of a standalone application, a built in temperature sensor can be queried for air temperature measurement. It is however no replacement for a dedicated air temperature sensor / radiation shield set up.
