Rain-Detection-System-via-Serial-Monitor-using-I2C-communication

Rain is a natural phenomenon that often occurs in several countries, especially tropical regions like Indonesia. This phenomenon can be a blessing and can also be a disaster for some people. Basically, this project was created to help the community in terms of rain detection. In addition, it aims to educate as well as make a real contribution to technological development. This project has been done and took approximately 3 days. This device can work well with or without water. When in wet conditions, the sensor will turn on the LED and send a response according to the situation. When dry, the sensor will turn off the LED and send a response according to the situation. The innovation applied in this project is I2C communication. The system interface can be accessed via Serial Monitor.

Basic Knowledge

Basically, a device can be communicated with other devices either wirelessly or by cable. Communication between commonly used hardware is Serial Communication. It can be known that there are three types of Serial Communication, which include: UART (Universal Asynchronous Receiver-Transmitter), SPI (Serial Peripheral Interface), and I2C (Inter Integrated Circuit). I2C (Inter Integrated Circuit) is a two-way serial communication standard that uses two channels to send data (OUTPUT from Master to Slave) and receive data (INPUT from Slave to Master). I2C uses two bidirectional lines: Serial Data (SDA) and Serial Clock (SCL) to transfer data and synchronize communication between devices. Each device connected to the I2C bus has a unique address that identifies it during communication. The I2C protocol allows multiple devices to share the same bus, and each device can act as a master or a slave. Master is the primary device that has full authority over the control of the Slave, while the Slave is the secondary device that is under the authority of the Master device.
