Description

CDY-15A Optical Rain Sensor

The CDY-15A optical rain sensor features a long maintenance-free period and excellent adaptability. It can be widely utilized for automatic rainfall monitoring in harsh environments. Optical rainfall sensor plays a key role in automatic monitoring and early warning of severe precipitation such as rainstorm, mountain flood and debris flow, and has good popularization value and application prospect.

Application

Meteorology and climate research:

◉Optical rainfall sensor is one of the important equipment for measuring precipitation in weather station. It calculates rainfall by detecting the blocking or scattering of light by raindrops. Compared with traditional rain gauge, optical rain sensor has higher precision and real-time performance. In meteorological observation, we can accurately measure the intensity and cumulative rainfall of each rainfall event. This measurement provides more accurate data support for meteorological forecasts.

◉In the aspect of meteorological disaster monitoring such as rainstorm and flood, optical rainfall sensor can quickly respond to rainfall changes. When the rainfall increases sharply in a short period of time, reaching the disaster warning threshold, the meteorological department can quickly issue early warning information.

Agricultural:

◉We install optical rainfall sensors in farmland to monitor rainfall in real – time. Then, farmers can utilize the rainfall data these sensors provide to decide whether irrigation is necessary.

◉Farmers can also use data from optical rain sensors to optimize irrigation strategies. They can record rainfall and crop growth over time, and then analyze irrigation patterns that are best suited to crop growth.

Transportation sector:

◉Optical rainfall sensors are installed along the highway to monitor rainfall in real time. When the sensor detects rain, it transmits the signal to the traffic management system.

◉Optical rain sensors are installed around airport runways and taxiways to accurately monitor rainfall on the runway surface. Water or slippery runway will affect the friction between aircraft tires and runway, which poses a threat to the safety of aircraft taking off and landing.
