Design and Implementation of a Temperature and Humidity Control System for a Poultry House Prototype

Abstract

This paper presents a Microcontroller based temperature-humidity measuring and control system which can be implemented in a poultry farm. The control of temperature and humidity have, overtime, become a major part of control systems operated in environment where these quantities are crucial entities. In this project, DHT11 temperature-humidity sensor is used for the sensing of the temperature and humidity of the poultry house, which is an input to the microcontroller. The microcontroller will get the temperature and humidity of the poultry from the temperature-humidity sensor and then compare it with the desired temperature for the poultry. If the measured temperature and/or humidity is not within the desired temperature and humidity of the poultry house, the control mechanism will be activated. The control of temperature and humidity is achieved through the use of some control mechanisms which include: fan, automated windows and heat source. The microcontroller used is the ATMEGA328p microcontroller. The temperature and humidity of the poultry is displayed on a Liquid Crystal Display (LCD). The result obtained is the control of the temperature and humidity of the poultry house.
