Description:
The Smart Optical Rain Sensor offers instantaneous and dependable detection of rainfall variations on glass, providing real-time data on precipitation levels (no rain, light rain, moderate rain, heavy rain). Its key advantage lies in its robust performance, unaffected by common environmental factors such as direct sunlight, accumulated dust, and obstructing foliage, thanks to an integrated intelligent optical filtering algorithm. The sensor's remarkably small form factor, with a diameter of approximately 12.5mm, ensures seamless integration into a wide array of devices, particularly cameras with stringent size limitations like box and speed dome types. This compact module is a valuable asset for applications requiring accurate and timely rainfall data, including security surveillance, smart building management, and precision agricultural monitoring.
