Crop Irrigation and monitoring System using Programmable logic Controller

Now a days automation and monitoring of crop irrigation is required for quality production of the crop. In this paper wheat, tomato and rice are considered for the study. A PLC based system is developed for monitoring and automation of these crops at various stages of growth. For the simulation of the system TwinCatTM software is used. For wheat crop temperature is monitored at germination, growth, and grain filling stages. Also, for wheat irrigation schedule is simulated. For tomato temperature is monitored at various growth stages. For rice crop temperature, soil moisture and humidity content are considered. The monitoring system helps the farmers to maintain the desired conditions for the respective crop
