Design of Raindrop detector based on Arduino

The Internet of Things technology and sensor technology can be used to analyze and process the rainy day data, and the raindrop detector based on Arduino is built. Arduino is a convenient, flexible and easy-to-use open source electronic platform, including various hardware and software versions. Arduino is built in an open source panel and USES a development environment similar to Java and C language. It mainly consists of two parts. The first part is the hardware part, that is, the designed hardware circuit is connected to the Arduino board, and the other part is the Arduino IDE. The sensors used include water level depth sensor, large area raindrop sensor and temperature and humidity dht11 sensor. By connecting these sensors to the Arduino board, and then writing the code of the sensor and the code connected to the mobile phone network into the board, the monitoring of rainy weather can be realized.
