The automatic plant watering system uses an Arduino and soil moisture sensor to maintain optimal soil moisture. When the soil is dry, the sensor activates a relay to turn on a water pump. Once the ...

This project is a smart, Arduino Nano-based automatic liquid dispensing system. It uses a water pump, solenoid valve, and flow sensor to control the amount of liquid dispensed. A Nextion display is ...

Water storage often presents challenges such as monitoring tank levels, preventing overflow, and reducing manual intervention to operate the pump. Two types of devices, known as water level indicators ...
