Leaf Wetness Sensor TS 253

Featured Features:

  • The maximum electrical output is achieved for a wet
    sensor, which is approximately 0.01 times the power
    supply connected to the sensor.

The TS253 Sensor is designed to simulate a sheet and measure the dry / wet condition.
To do this, it uses a printed circuit board on which there are 2 conductive lines with a certain proximity to each other which are covered in gold to prevent corrosion from exposure to the weather. These 2 conductive lines are insulated, in the presence of moisture on the surface there is an electrical conduction between them. This can be interpreted as a variable resistance depending on the degree of existing humidity:

 

  • Dry Sensor: R sensed = ∞
  • Wet Sensor: R sensed = 0
