Optical rain sensor works:
Optical rain sensor mainly by the light source, light source integrator, sampling space, receiver, data processing part of the composition.
When the raindrops (or snow particles and other precipitation particles) through the sampling space, Rain drops will block the laser, The received optical signal received by the sensor and the electrical signal (such as voltage or current) converted by the optical signal will change, When the raindrops pass through the sampling space, Accept the sensor's electrical signal and restore the state of the raindrops before entering the sampling space. When the raindrops cross the sampling space, The electrical signal of the receiving sensor is processed, You can get the rain through the sampling space time.
Optical Rain Sensor Features:
Optical rain sensor with a long maintenance-free, good adaptability and so on, Can be widely used in harsh environments with automatic rainfall monitoring. Optical rain sensor in the rainstorm, flash floods, debris flow and other disastrous precipitation weather automatic monitoring, Early warning plays a key role, has a good promotion value and application prospects. At the same time, optical rain sensing technology research can fill the gaps in the field of domestic, For the localization of meteorological instruments to contribute.
