SYCBA RAIN is an innovative rain gauge that uses optical sensing technology, that overcomes many of the shortcomings of conventional tipping bucket rain gauges.
The Rain Gauge senses water hitting its outside surface using beams of infrared light, modelling the principle used in automotive rain-sensing windshield wiper controls.
The optical gauge bounces the infrared beams within the sensor lens, and as rain drops hit the surface, the infrared light escapes through. Changes in the intensity of the infrared beams during rainfall are directly correlated with the size of the rain drop. The system automatically compensates for condensation and very small drops; it can detect rain drops less than a half millimetre in size!
The compact size makes them ideal for wet weather notification systems or remote rain gauges where periodic maintenance is not possible.
