4. Automatic irrigation is the use of a
device to operate irrigation structures
so the change of flow of water from
bays can occur in the absence of the
irrigator.
5. Agriculture is
number one
consumer of water.
It is nearly
impossible for
cultivating crops in
dry and arid regions
Consumption of water in Agricultural Sector
6. • Arduino UNO
• Soil Moisture Sensor ( with LM393 Driver)
• LM 35 Temperature Sensor
• 16x2 LCD Display
• Water level Switc
• 5V Relay
• BC547 or similar NPN Transistors
• Resistors ( Refer Circuit Diagram)
• Potentiometer ( 10Kohm )
• 5mm LED
• 1N4007 Diode
• Terminal Strips and Screw Terminals
• Breadboard
7. Arduino UNO is a low-cost, flexible, and
easy-to-use programmable open-source
microcontroller board that can be
integrated into a variety of electronic
projects.
We have used arduino for controlling the
relay which is connected to the pump
according to the data collected from the
sensors.
8. Soil moisture sensors measure or
estimate the amount of water in the soil
In our Circuit Moisture sensor collects
the data of the soil’s moisture and sends
to arduino.
9. LM35 is a temperature measuring device
having an analog output voltage
proportional to the temperature.
20. • This type of irrigation prevents wastage of water and enhances plant health.
• No human intervention required once the circuit is ready and working.
• Very Less possibilities of failures and errors as it does not require any wireless
mode of transmission of signals.
• It works independently .
21. • It costs around Rs.3000 for making one circuit.
• It is costly for making circuits all over the agricultural land
• But this can overcome the problem of over usage of water in agricultural
• This is an one time investment
