In the agricultural field, as the rainwater is spread unevenly; the distribution of water according to the need ofthe crop is not easy to control. Because of no appropriate irrigation approachfarmers suffer huge financial loss. In India, farmers manually irrigate theland at regular intervals. This technique sometimes eats up more water orsometimes the water reaches late and crops get dried. To overcome this situation,we use Auto irrigation system in which the irrigation will happen only whenthere is enough need of water.
DESIGNAND IMPLEMENTATIONThe goal is to provide Water Management inIrrigation System with monitor and controls. It is designed to solve unnecessarywater flow in agricultural field. The water level in the field can be monitoredon a mobile application through internet. This application shuts the supply of water automaticallyirrespective of physical location of the user provided internet connectivity.To keep track the moisture content of the soil turn on the sprinklersautomatically when the content of water goes down a certain level. Without visitingthe farm, the user can examine whether the farm is irrigated through the mobileapplication.
One of the most important aspects of IOT is extraction of highlevel information from raw sensory data. The main component of the system isthe microcontroller which acts as a bridge between the sensors and the mobileapplication.METHODOLOGYThe algorithm is as follows:Step 1: Begin the technique. Step 2: The initial power is supplied tomicrocontroller. Step 3: Checksoil moisture level and the humidity level. Step 4: If moisture content in soil is higher than afixed value, then there is no need of irrigation. Step 5: If the soil moisture content is less than afixed value, then start irrigation, same as for humidity, start sprinkler.
Step 6: When the water reaches the prescribed point ofwater level sensor then the irrigation system stops itself and sends themessage about the moisture content and the humidity. Step 7: User can operatethe system remotely through a web page.COMPONENTS1) SOIL MOISTURE SENSOR 2) HUMIDITY SENSOR3) 8051 MICROCONTROLLER4) WATER LEVEL SENSOR5) WEBPAGE6) RESISTOR7) GPRSRESULTSDepending upon the humidity and moisturelevel in the soil, Irrigation system works. Auto Irrigation System is operatedwith less manpower. Proper amount of water should be supplied because over-wateringand under-watering affects the crop.
