“Soil Moisture Sensor - Water Pump - Water Level Sensor - MOSFET - Circuit - Code
This project shows how to build a self-watering system whose values can be monitored through an app. The project includes both a breadboard circuit and a printed circuit board design. The project measures both the water level sensor and the soil moisture sensor value and runs the system within the specified time interval, and the self-watering function is executed.
Although the breadboard circuit of the project looks complicated you can build the circuit by following the shared circuit diagram, and you can test that all components work correctly. The circuit uses a Neopixel LED for ultraviolet light, a water level measurement sensor, a soil moisture measurement sensor, a MOSFET that acts as a switch to activate the motor, and of course the water pump motor.
