Poultry House Environment Controller Kit with Arduino Mega + DHT22
Automate Your Poultry House Climate with This Arduino Mega & DHT22 Controller Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Poultry health and growth depend on precise environmental control — temperature, humidity, CO₂, and light must follow a strict schedule that shifts as chicks mature. This kit lets you build a full-featured controller that monitors all four parameters and drives fans, heaters, and lights based on a flock-age schedule you program.
What You'll Build
You’ll assemble and program a working climate controller for a poultry shed. The system reads two DHT22 sensors for temperature and humidity, a CO₂ sensor to prevent buildup, and a light sensor to maintain optimal daytime brightness. The Arduino Mega processes the data, logs it to an SD card, displays real-time values on the OLED, and commands a 4-channel relay to switch ventilation, heating, and lighting appliances.
What You'll Learn
- Interface multiple I2C and analog sensors with Arduino Mega and resolve address conflicts
- Implement a flock-age-based schedule that updates temperature and light setpoints automatically each week
- Log time-stamped sensor data to an SD card using the DS3231 real-time clock
- Wire and code a 4-channel relay to safely control 230V AC fans, heaters, and bulbs

Who This Kit Is For
This advanced electronics kit is designed for B.Tech students (ECE, EEE, Agricultural Engineering) building IoT capstone projects, CBSE Class 12 innovators participating in ATL tinkering or science fairs, teams in Smart India Hackathon tackling agri-tech problems, and progressive poultry farmers who want to build their own automation rather than buying expensive commercial units.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to access an AI companion trained on this specific kit; you’ll get step-by-step troubleshooting. For urgent issues, reach our team via WhatsApp.
Can I change the temperature schedule for different bird ages?
Absolutely. The provided code includes editable arrays for weekly setpoints, and the AI assistant can guide you in adjusting parameters for broilers, layers, or breeders.
Will this kit work with a 12V battery for a remote poultry farm?
Yes, you can power the Arduino and sensors directly from a 12V battery; the relay module’s high-voltage side must be supplied separately. All sensors are 5V tolerant and low-power.
How do I protect the electronics from dust and ammonia in a poultry shed?
Place the controller board in a sealed IP65 enclosure (not included) and use cable glands. The DHT22 sensors should be mounted in ventilated but protected housings. Regular cleaning of sensor openings is advised.
Temperature, humidity, CO2 and lux all monitored. Relays control ventilation fan, heater and lighting per flock age schedule.
