2 piezoelectric rain sensors ......

Piezoelectric rain sensors use the impact measurement principle to measure the weight of individual raindrops and thus calculate the amount of rainfall. The raindrops are influenced by the weight of the raindrops and air resistance during their fall. When they reach the ground, the velocity is constant. According to P= mv, the weight of raindrops can be calculated by measuring the impact, and thus the continuous rainfall can be obtained.

The maximum rainfall intensity that can be measured is 8 mm/min, which is twice the range of conventional rainfall monitoring.

The piezoelectric rain gauge integrates all components in one housing without any exposed components, eliminating the influence of leaves, dust, insects and other impurities on data accuracy and reducing the disadvantages of maintaining different functional components.

FT-YL3A

The sensor consists of an upper cover, a housing and a lower cover. The housing contains the piezoelectric sheet and circuit board and can be fixed to a 50 mm outside diameter post and weather station crossbar. The sensor uses the impact measurement principle to measure the weight of individual raindrops and then calculates the amount of rainfall. The raindrops are affected by the weight of the raindrops and air resistance during their fall. When they reach the ground, the velocity is constant. According to P = mv, the weight of raindrops can be calculated by measuring the impact, which in turn gives continuous rainfall.

FT-YL3B

An advanced small piezoelectric sensor module is used internally to measure the intensity of rainfall using the voltage effect technique generated by raindrops hitting the piezoelectric module. The piezoelectric rain detector can detect the start and end of rainfall more sensitively and quickly than traditional mechanical rain detection methods, without worrying about moving objects such as leaves and branches shifting above the detector to affect rain detection. An optional internal heating device is available to prevent freezing.

No moving parts inside the sensor, maintenance-free, small size and low energy consumption.
