Design and Implementation of IoT Based Soil Moisture Data Logger for Irrigation and Research Applications

Abstract

Abstract A fundamental way to schedule irrigation is possible through the continuous monitoring and management of soil moisture. Soil moisture is directly related to soil water content and this water content will affect the quantity of nutrients available to plants and soil aeration status. Proper irrigation can be done with the help of the accurate measurement of soil moisture. This proposed system is capable to collect the soil moisture content using watermark 200SS sensor and will be recorded in the permanent storage medium and will be accessible through wireless media. The soil moisture value is calculated in Centibar (cb) or Pascal ( SI unit ) based on the resistance value of soil moisture sensor and temperature sensor.This cost-effective system will be useful for irrigation, automatic plant watering, and get the details of the soil moisture. The system has been tested in different environmental conditions and verified the values. The system is completely powered by solar energy and consuming very less amount of processing power to run.
