The Raindrops Detection sensor module is used for rain detection. It is also for measuring rainfall intensity. The rain sensor can be used for all kinds of weather monitoring and translated into output signals and AO.
The rain sensor can be used to monitor a variety of weather conditions and turned into several fixed output signal and Analog output.
It includes a printed circuit board (control board) that “collects” the raindrops. As raindrops are collected on the circuit board, they create paths of parallel resistance that are measured via the op-amp. The lower the resistance (or the more water), the lower the voltage output. Conversely, the less water, the greater the output voltage on the analogue pin. A completely dry board, for example, will cause the module to output 5V.
The robot kit for raindrop, rain, humidity sensor plant leaves can be used to monitor various weather conditions and has relay outputs that directly control the motor as well as other startup and shutdown.
This Raindrops Detection Sensor Module with 12V Relay Module sensor is made of high-quality double-sided fr-04 item material with a large area of 5.0* 4.0cm and a surface coated with nickel. It has the characteristics of oxidation resistance, electrical conductivity, superior performance and long service life. It is directly equipped with power relay module for load control. you can Adjust the sensitivity distribution position and control the opening of the relay under different humidity control.
When the power is plugged in, the power indicator light is on without water sensors, relays, switches for starting related equipment, indicator lights, dripping water, relays are off, lights on and off are not on.
