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.
Raindrops Detection Sensor Module Rain Weather Module for Arduino, etc. 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 analog pin. A completely dry board, for example, will cause the module to output 5V.
The module includes a rain board and a control board that is separate for more convenience.
It has a power indicator LED and an adjustable sensitivity though a potentiometer. The module is based on the LM393 op-amp.
1 x Rain Sensitive Sensor Module, Rain Drop Detection Sensor Module/Raindrops Humidity Sensor for Arduino
Works well. works good with arduino.
It can be used with other weather conditions also. happy with the product.
This sensor is working fine
Works like a charm.
High Quality sensor....but price is bit high and my order delivery was long..and late...satisfied with it!
