CAPACITIVE RAIN SENSOR

capacitive rain sensor

AUREL SPA has developed a ceramic capacity sensor, component able to notice the presence of water on its surface.

It’s realized on ceramic substrate and thanks to its sensitivity area is able to change the capacity depending on the ratio water accumulated on it.

The technology (glassy coverage of substrate) guarantees high reliability due to the great stability of the support and the inalterability of the surface “sensitive”, also after cleaning with solvents and/or heavy external conditions of employment.

Moreover in presence of the water, the capacitance goes to high values compared to dry conditions and the ratio changing is over 400%.

Ceramic rain sensor application

  • Sensors for rolling shutters
  • Sensors for awnings
  • Weather stations
