- 3. WHY? • India is mainly an agricultural country. • Agriculture plays vital role in the development contributes about 16% of total GDP and 10% of total exports. • According to UN Food and Agriculture organization 60 percent of water pumped for irrigation is wasted. • In regard to save water and time we have proposed project titled Arduino based automatic irrigation system. • By using Internet technology and sensor network technology we can control water wastage. • It can greatly improve the utilization of water and can increase water productivity.
- 4. INTRODUCTION • We have created a system using Arduino to measure the moisture level of plant and to efficiently deliver water to it. • In this proposed system, we are using soil moisture sensor that sense the parameters of the soil. • Based on soil moisture value land is automatically irrigated by ON/OFF of the motor. • These sensed parameters and motor status will be displayed on user android application. • Arduino is used for controlling the whole process and GSM module is used for sending alert messages to user on his Cellphone.
- 5. REQUIRED COMPONENTS • Arduino Uno • Soil Moisture Sensor • GSM Module • Relay 12v • 16x2 LCD • Transistor BC547 (2) • Connecting wires • Water cooler pump • Resistors (1k, 10k) • Voltage Regulator IC LM317 • Power supply 12v 1A
- 6. ARDUINO • Arduino is used for controlling whole the process of this Automatic Plant Watering System. • The output of soil sensor circuit is directly connected to digital pin D7 of Arduino. • A LED is used at the sensor circuit, this LED’s ON state indicates the presence of moisture in the soil and OFF state indicates the absence of moisture in the soil.
- 7. MOISTURE SENSOR • Uses two probes to pass current through the soil and then reads the resistance to get the moisture level. • Power: 3.3 V or 5 V • Output voltage signal: 0-4.2 V • Current: 35 mA
- 8. GSM MODULE • Here we have used TTL SIM800 GSM module. • The SIM800 is a complete Quad-band GSM/GPRS Module which can be embedded easily by customer or hobbyist. • The design of this SIM800 GSM Module is slim and compact.
- 9. RELAY • A 12V Relay is used to control the 220VAC small water pump. • The relay is driven by a BC547 Transistor which is further connected to digital pin 11 of Arduino. • An optional LCD is also used for displaying status and messages.
- 10. LCD • Stands for “Liquid Crystal Display” • A 16x2 LCD means it can display 16 characters per line and there are 2 such lines. • In 16x2 LCD each character is displayed in a 5×7 pixel matrix. • works on the principle of blocking light rather than emitting light.
- 11. WORKING EXPLANATION • First of all, it is a Completely Automated System . Arduino is used for controlling the whole process and GSM module is used for sending alert messages to user on his Cellphone • If moisture is present in soil then there is conduction between the two probes of Soil Moisture sensor and due to this conduction, transistor Q2 remains in triggered/on state and Arduino Pin D7 remains Low. When Arduino reads LOW signal at D7, then it sends SMS to user about “Soil Moisture is Normal. Motor turned OFF” and water pump remains in Off state. • Now if there is no Moisture in soil then Transistor Q2 becomes Off and Pin D7 becomes High. Then Arduino reads the Pin D7 and turns On the water motor and also sends message to user about “Low Soil Moisture detected. Motor turned ON”. Motor will automatically turn off when there is sufficient moisture in the soil.
