Smart Irrigation

Scenario Description

• Our institute (LNM Institute of Information Technology) is situated, in the middle of several small villages, approx. 20 KMs away from Jaipur railway station.
• Villagers in the vicinity of our institute still use conventional techniques for irrigation. Such methods are causing sever dip in the ground water level causing problems to the villagers as well as the institute.
• Villagers are unaware of the new technologies to be adopted for intelligent irrigation and most of the solutions available in the market are beyond their purchasing capacity.
• After conducting a small survey on the irrigation related issues in the near by villages as well as in broader perspective for similar Indian farmers our team decided to design and implement a solution to overcome irrigation related issues using state of art sensor network but at the cheapest cost possible.

Our aim is to use our knowledge to provide a state of art intelligent irrigation system to Indian farmers irrespective to the crop they are cultivating, type of soil, and irrigation technique being used at the cheapest cost possible.

Proposed Solution :-

• Fully adaptive sensor network based irrigation system with very high power efficiency.
• Intelligent irrigation system to adopt different types of soil, crops, depth and moisture level for crops as well as vegetables.
• Simple to use minimalistic hardware solution to be used by any farmer.
• Cheap solution to avoid financial burden on even small farmers.
• Technical Details :-
• Sensor network designed using nRF24L01 in which each node can communicate with subordinate node up to a distance of 100 meter.
• Mesh topology is used to design the network which means this network can cover farmlands of any size.
• Use of sleep mode in this network can extend the battery life of each node/complete network to a year with single 9v battery.
• Capacitive sensor developed, tested and calibrated in-house reduces the overall cost of each sensor node.
• Fully adaptive sensor network to adjust routing of data from alternative sensor nodes in case failure of nearby sensor/sensors.

Use of separate wireless links like GSM, GPRS, Ethernet and NRF links for secure and robust communication between different entities of the complete network.

2. Working at Receiver

After the farmer’s input, and on pressing the EEPROM button :-

1. The Moisture threshold is set into the EEPROM of the uC. This was intentionally put into the code to tackle the cases when the electricity goes off.

2. Sleep time is sent to the nodes and the receiver starts to run in the main loop. This was again a necessity to reduce the power consumption of the battery powered node.

3. Working of Node End

This is an on-going project and is being updated & will be updated on https://github.com/manvendra88/WSN-Soil-Moisture .

This is our team named - 'Indees', i could have never thought of doing anything in my life if these people weren't there. In the black suit is my Guru M.V. Deepak Nair (https://bit.ly/2z6E7qF), the man who made an engineer out of an ordinary child. The two guys on the right are my best-friends at work, Ritam and Mradul who taught me to be sincere and have a work-ethic in life.
