This work aims to provide details on how to build an automated Environment Controlled Poultry Management System (ECPMS) using low cost commodity hardware and open source software. A comprehensive system was built using Raspberry Pi, used as a Linux embedded system board and Arduino-Uno board for interfacing with different sensors. The system has been thoroughly investigated for various physical parameters associated with effective poultry management which includes temperature, humidity, moisture content in the air and air quality. It was found that the system not only monitors these parameters, but also regulates these parameters effectively. The framework was observed to be very useful for farmers as they could easily access and control the system remotely using their handheld mobile devices. The system reduces human intervention, saves time, optimizes resource utilization and increases poultry production.
