Abstract: The key objective of the paper is to monitor the soil moisture content during its dry and wet conditions with the aid of a moisture sensor ,an automated water inlet setup which can also monitor and record temperature, humidityetc. It controls the irrigation of Plants automatically where the need for human intervention can be reduced As water supply is becoming scarce in today’s world there is an urgency of adopting smart ways of irrigation The project describes how irrigation can be handled smartly using IOT. This project aims to save time and avoiding problems like constant vigilance. It also helps in conserving water automatically providing water to theplants/fields depending on the water requirements this system can also prove to be helpful in agricultural parks and lawns. The objective system is to detect the moisture content of the soil and depending upon its sprinkling of water. This entire information will be sent to the user’s mobile phone. The smart irrigation system was developed to optimize water use of crops.The system has a distributed wireless network of soil-moisture temperature sensors placed in the root zone of the plants. Also, a gateway unit handles sensor information, triggers, actuators, and transmits data to the web application. An algorithm was developed with threshold values of temperature and soil moisture that was programmed into a microcontroller-based gateway to control water quality the system was proved. The systemwas powered by solar panel and it has a duplex communication link based on a cellular network.Keywords: Soilmoisturesensors, IoT, Arduino,Android,Microcontroller,duplexcommunication.
