The Internet of Things (IoT) has the potential to revolutionize the way air filtration systems are controlled and managed in poultry farms. It describes the design and development of an IoT-controlled air filtration system in poultry farming. The system was designed to meet the specific requirements of the poultry farm, including the size and layout of the facility, the type of poultry being raised, and the environmental conditions present. The system has to be fabricated using specialized equipment and materials, and equipped with sensors and controllers that allow it to be monitored and controlled remotely using a smartphone. The proposed system consists of an air filter, a fan, a controller, and sensors. The air filter is designed to remove airborne particles from the air, such as dust, contaminated gases present in poultry farm like carbon monoxide, carbon dioxide, and ammonia. The fan is used to circulate the air in the poultry house and pull it through the filter. The controller is responsible for controlling the fan speed, filter cleaning schedule, and monitoring the air quality. The sensors detect the level of airborne particles and adjust the fan speed accordingly.
