Rain Drop Detection Sensor Module / Raindrops Humidity Sensor For Arduino
Category: Sensor Collections
Rain Drop Sensor is used for rain detection & measuring rainfall intensity. This module includes a rain board and a control board that are 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 is placed PCB (control board) . The rain drops are collected on the circuit board, they create paths of parallel resistance that are measured through 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 & Output Side the both Analog & Digital output Also Varied.
- Operating voltage: 5v
- (A0,D0) Analog & Digital Output .
- Variable POT is Provided
- Output LED indicator
- Compatible with DIY Boards
- TTL Compatible
