Abstract

The Automated Poultry Farm Climate and Feed Monitoring System is designed to optimize the livestock environment and streamline feeding processes using IoT technology. The system utilizes an ESP32 microcontroller to integrate a DHT22 sensor for temperature and humidity tracking and an MQ135 sensor to monitor ammonia levels, which are critical indicators of air quality in poultry sheds. When environmental parameters exceed predefined thresholds, the system triggers ventilation fans via relay modules to maintain an ideal climate. Simultaneously, a servo-driven mechanism automates the dispensing of feed and water based on a programmed schedule. All real-time data is transmitted to a cloud-based IoT dashboard, allowing farmers to remotely monitor the shed's health and receive alerts, thereby reducing mortality rates and enhancing overall productivity through precision livestock management.

Project Description

Traditional poultry farming relies heavily on manual monitoring, which often leads to delayed responses to critical environmental changes. High ammonia levels from waste and fluctuations in temperature can cause respiratory distress and heat stress in birds, significantly increasing mortality rates and reducing growth efficiency. The objective of this project is to replace manual oversight with an automated, data-driven system that ensures a stable environment and consistent feeding cycles. The system adopts a closed-loop control approach. The ESP32 acts as the central hub, continuously polling sensors for temperature, humidity, and gas concentrations. If the ammonia levels rise or the temperature spikes, the system automatically activates exhaust fans to refresh the air. To address feeding inefficiencies, the project implements a timed dispensing system using servo motors, ensuring that birds receive the correct amount of feed at specific intervals, which prevents feed wastage and promotes uniform growth. By integrating these hardware components with an IoT dashboard, the system provides farmers with a transparent view of the farm's status from any location. This societal value is realized through the reduction of labor costs, the minimization of chemical interventions due to better air quality, and the overall improvement in animal welfare, making poultry farming more sustainable and scalable for small to medium-scale enterprises.
