IOT BASED SYSTEM FOR CONTINUOUS MEASUREMENT AND MONITORING OF TEMPERATURE, SOIL MOISTURE AND RELATIVE HUMIDITY

This paper proposes a much efficient and cost effective system for the farmers to monitor the various environmental parameters such as temperature, relative humidity and moisture required for the growth of crops. It also shows a comparison between two different types of soil moisture sensors to enable us to choose the better one. This system measures the ambient temperature, soil moisture and relative humidity using DHT11, capacitive soil moisture sensing circuit and resistive soil moisture sensing circuit. It transmits the same to the cloud server for remote access.
