MSP 430 Lunch Box Based Smart Irrigation System

The continuously increasing population in India demands for the rapid improvement in food production technology. Indian, economy is mainly based on agriculture. Water is the main resource for agriculture. Hence efficient water management of fresh water resources has a crucial importance. To save the water and to increase the yield of crop proper method of irrigation must be used. It is well known that irrigation is very economical and efficient. The conventional automated irrigation system is fully controlled and monitored by the farmer. This paper presents a fully automated irrigation system which is controlled and monitored by using MSP430 processor. Sensors are used to monitor the moisture content of the soil and depending on that the valves of the system are turned ON or OFF automatically for different interval of time. Turbidity sensor plays a important factor to be considered as it affects the chemical particles availability in the water. Sensor to detect the purity of the water is used and depending on the value of the soil moisture sensor, suggestions are given to the farmer to maintain the proper water.
