Soil Moisture Sensor Using Arduino Uno

 Soil Moisture Sensor Using Arduino Uno.

Hardware Required

1. Breadboard
2. Soil moisture sensor
3. Arduino Uno board
4. LED
5. Jumper wires

Connections

1. Connect the soil moisture sensor to the breadboard.
2. Connect the VCC pin of the soil moisture sensor to the 5V pin of the Arduino board using male-male jumper wires.
3. Further, the GND pin of the soil moisture sensor is connected to the negative terminal of the LED. Also this GND pin is connected to the GND pin of the Arduino board.
4. The A0 pin of the soil moisture sensor is connected to the A0 pin of the Arduino board.
5. The circuit is ready.

Programming the Arduino Board

• In order to use the circuit, we need to code the Arduino board. The code is as follows:

Working Principle

•  A soil moisture sensor measures the water content in the soil. It helps optimize irrigation by preventing overwatering and ensuring plants receive adequate water for healthy growth.
•  These sensors utilize various technologies, including electrical resistance, capacitance, etc., to measure the water content (moisture) which is present in water.
