Objectives
To reduce the cost of labor. Saving the time is the major purpose of this project. To save the plants from being rotten because of over
irrigation.
Embedded System
A microcontroller or microprocessor based system that is built to control the functions of equipment, machinery or plant.
Combination of hardware and software for specific application.
Apparatus
Hardware:• Moisture Sensor module• Arduino UNO• 12V Solenoid Valve• Adapter 12v• Resistor 1k ohm• Diode 1N4007• Transistor TIP122• Bread Board
Software:• Arduino IDE
How does it work:
We will set a fixed moisture level for three moisture sensors in the Arduino UNO.
The three moisture sensors will detect the moisture level from the soil.
When the detected level of moisture will exceed the given level in the Arduino UNO, then water supply through solenoid Valve will gonna be off.
Until then the water supply will go on.

Block Diagram:
Arduino UNO:
Arduino Uno is a microcontroller. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button.
Moisture Sensor:
This is a simple water sensor can be used to detect soil moisture when the soil moisture deficit module outputs a high level, and vice versa output low.
Operating voltage 3.3V-5V.
Solenoid Valve:
The 12V solenoid controlled fluid valve. Simply connect a fluid source to the ¾" threaded inlet and it will interrupt the flow until 12V is applied to the fast-on connectors on the solenoid.

Limitations of this Project:
We didn’t use a gravity-feed solenoid valve. This means that we will need
3 PSI water pressure to fully open the valve. As the moisture sensor can’t cover the whole field, the moisture value
may vary. Moisture Sensor does not give absolute reading of moisture, gives
relative.
Thank You!
