The Rain Drop Sensor is a module that detects rain or water droplets. When water makes contact with the sensor's surface, it creates a conductive path between the sensing electrodes, causing a change in conductivity. The sensor provides an analog output signal that can be connected to a microcontroller for rain detection. It is used in weather monitoring systems, smart irrigation, and water level monitoring applications.
Rain Drop Sensor
Specification
- Operating Voltage: 3.3V to 5V
- Sensitivity Adjustment: Potentiometer for sensitivity adjustment
- Output: Analog signal
- Dimensions: Varies depending on the module
Usage
-
Power Supply: Connect the VCC pin of the sensor module to the positive supply voltage (3.3V to 5V) of your microcontroller or development board.
-
Ground: Connect the GND pin of the sensor module to the ground (0V) of your system.
-
Analog Output: Connect the analog output pin of the sensor module to an analog input pin of your microcontroller or an analog-to-digital converter (ADC) module.
-
Sensitivity Adjustment: Some rain drop sensor modules include a potentiometer for sensitivity adjustment. You can adjust the sensitivity level by turning the potentiometer to set the desired threshold for rain detection.
