Soil Moisture and Temperature sensor based intelligent irrigation water pump controlling system using PIC 16F72 Microcontroller

This paper aims in providing a user friendly, reliable and automated water pumping system. The paper aims in designing a system which is capable of detecting moisture level in the soil and capable of taking the decision of switching ON/OFF water pump. The system also uses temperature sensor to detect the temperature and automatically the fan speed can be controlled like coolants. In this paper we make use of one microcontroller PIC16F72, which is dedicated at the water pump. The microcontroller forms the heart of the device and there are also soil-moisture sensors, which are meant for detecting the moisture in the soil and is programmed with the proteus software. The system also uses temperature sensor based fan speed control system using DC fan. The proposed technique can help in reducing deaths of people due to current shocks at fields and also to on/off the motor automatically by using soil moisture sensors at fields which avoidsthe need of a human being. Key-Words: -Soil moisture, temperature, sensor ,PIC16F72, D.C fan, Proteus software. _____________________________________________________________________________________________________
