Introduction:
An Automatic Plant Watering System is based on a Soil Moisture Sensor, which is placed in the soil of the plant and when the reading of the sensor is below the pre-set value, the pump will be activated, LCD display “Moisture level low, soil wet and pump on”. On the other hand, when the reading of the sensor is above the pre-set value, the pump will be deactivated, LCD display “Moisture level high, soil moisture and pump off”.
Required Component for Automatic Plant Watering:
- Arduino UNO R3
- Soil Moisture Sensor
- Potentiometer
- Resistor
- Inductor
- Capacitor
- LCD
- LED
- Motor
- Voltmeter
When the moisture
level of the soil is detected low pump is activated, and the LCD displays Soil moisture low,
Soil wet. On the other hand, when the sensor detected Soil level is high pump
becomes deactivated and the LED become activated, LCD displays the Soil moisture level
High, Soil Moisture.
