Piezoelectric rain sensor

1. Overview of piezoelectric rain sensor products

Piezoelectric rain sensor is also called piezoelectric precipitation sensor and digital Internet of things rain sensor. Piezoelectric rain sensor PVDF piezoelectric film is used as a rain sensing device, which can monitor from light rain to heavy rain, and measure and calculate a single raindrop. Calculate rainfall. The piezoelectric rain sensor uses PVDF piezoelectric film as the rain sensing device, and distinguishes the raindrop signal through the embedded AI neural network to avoid false triggering caused by interference such as sand, dust, and vibration.

It is widely used in meteorological environment monitoring, hydrology and water conservancy comprehensive monitoring stations, traffic road monitoring, agriculture and forestry, wind power generation and other relevant departments to remotely measure the amount of precipitation, precipitation intensity, and the start and end time of precipitation. It is used for flood control, water supply dispatching, hydrological automatic measurement and reporting system for the purpose of water regime management of power station reservoirs, automatic field measurement and reporting station, etc.

2. Functional characteristics of piezoelectric rain sensor

1. Integrated design, beautiful appearance

2. No mechanical parts, no exposed parts, can filter similar signals introduced by environmental factors such as leaves, dust, insects, etc.

3. High measurement accuracy, wide range, good stability, low power consumption, strong ability to resist external interference

4. Can work around the clock, not affected by weather changes, accurate to second rainfall duration monitoring

5. Maintenance-free, the raindrop contact surface is an arc-shaped design structure, no rainwater is stored,

6. With automatic horizontal calibration function after installation, no on-site calibration is required

7. Small size, easy to carry, disassemble and install

3. Technical parameters of piezoelectric rain sensor

6. Precautions for piezoelectric rain sensor

1. There is no occlusion within a radius of 1 meter around the sensor level to avoid the impact of water droplets splashing

2. The installation position of the sensor should avoid strong mechanical vibration sources

3. There should be an open area above the sensor installation, and the raindrops should drop directly to the sensor, avoiding secondary dripping and continuous water impact
