A study on smart irrigation system on a watershed

Abstract

Automatic irrigation system was carried out on a small area. The study was confined to Parlakhemundi area of Gajapati district situated in agro-climatic zone-5. The main focus of the study is to plan automatic irrigation, when the soil moisture level decreases to certain extent then only irrigation is provided and the other is to check the accuracy of the sensors compared to other instruments in our given plot. As irregular irrigation causes lot of wastage of water. So, in order to save water and time IOT has been used (PC based). There are various sensors like temperature, humidity, soil moisture sensors which senses the various parameters of the soil and based on soil moisture value land gets automatically irrigated by ON/OFF of the motor. A comparison between the recordings i.e for soil moisture, recordings of both tensiometer and sensors are taken and the error between them is detected. Likewise for temperature and humidity both the recordings are compared and error is detected. Mulches i.e. straw, grass, saw dust and combination of saw dust and grass is taken into account.
