IOT Based E-Crop: Smart Agriculture Monitoring System for Sri Lanka

Abstract

In today’s technological era in agriculture, automation is very much vital. Farmers in Sri Lanka use wireless sensor networks in monitoring many parameters in agriculture. Because of the erratic natural distribution of rainwater, agriculturalists find it difficult to control and monitor the distribution of water to agriculture fields throughout the farm or according to crop requirements. In Sri Lanka, there is no perfect irrigation system for every soil structure, weather condition and diversity of crops cultures. Sri Lankan Farmers face huge economic losses because of incorrect prediction of inappropriate irrigation systems and weather conditions. In this background, with the advancement of sensor devices organized with wireless technologies, it can remotely monitor parameters such as moisture, humidity and temperature. It creates and deploys a wireless sensor network that is connected to a central node the use of Wi-Fi, which in turn is associated to a Central Monitoring Station (CMS)through General Packet Radio Service (GPRS) or Global System for Mobile (GSM)technologies. According to the soil humidity sensor value the mote generates the water irrigator during the time-frame of water shortage. Once the field is sprinkled with satisfactory water, the water irrigator is switched off. Also, the pH sensor value of soil is directed to the base station and in turn base station intimates the planter about the soil pH via SMS using GSM modem This system is predictable to support planters in identifying soil situations and turn accordingly in Sri Lanka.
