So in this project we have to make a device or a system called smart water plant, it uses Arduino UNO, soil moisture sensor, 2 relay module, DC pump, hose and wires. How this device or system works is that when the soil moisture is plugged in to a dirt or mud it will detect the humidity of it and if the dirt is too dry it will send a signal to the Arduino and the the Arduino will send the signal to the relay so it can connect to the electricity and the dc pump can send water to the using using the hose.
