Arduino Mega Poultry Environment Controller Kit - CO2, Temp, Humidity Sensor
Poultry Shed Environmental Controller Kit with Arduino Mega + DHT22
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Create a fully automated environmental control system for poultry sheds, hatcheries, or smart-farm monitoring rooms. This kit monitors temperature, humidity, CO2, and ambient light with industrial‑grade sensors, then controls ventilation fans, heaters, and lighting based on a flock‑age schedule stored in the RTC and microSD card. Perfect for agriculture engineering projects, Smart India Hackathon prototypes, or final‑year B.Tech submissions where real‑time sensor fusion and actuator control matter.
What You'll Build
You will assemble, calibrate, and deploy a standalone controller that reads DHT22 sensors for temperature/humidity at two spots, an MH‑Z19B for CO2, and a BH1750 for lux. The DS3231 RTC triggers relay actions—fan on above 30°C, heater on below 18°C, lights adjusted by flock age—and logs all data to microSD with timestamps. The 0.96” OLED displays real‑time readings and relay status, giving you a professional‑grade monitoring station.
What You'll Learn
- Interface and calibrate DHT22, MH‑Z19B (NDIR CO2), and BH1750 I2C sensors with Arduino Mega
- Implement PID‑like threshold logic for relay control of ventilation, heating, and lighting
- Use DS3231 RTC to store and execute a daily schedule based on flock age (0–42 days)
- Log sensor data to a microSD card in CSV format and display key metrics on an OLED in real time

Who This Kit Is For
This advanced kit is built for B.Tech ECE/EEE students tackling environment‑control capstone projects, Smart India Hackathon teams prototyping precision livestock farming solutions, and researchers at IIT/NIT/VIT/BITS working on agricultural IoT. It assumes prior experience with Arduino IDE and basic soldering; everything else is included.
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 on the box to chat with the AI companion trained on this project’s wiring, code, and calibration. It works on WhatsApp and email, giving you step‑by‑step answers until your controller is running.
Can I modify the flock age schedule for my own poultry cycles?
Yes. The code includes an editable look‑up table on the microSD card that maps age (in days) to target temperature, humidity, CO2 thresholds, and light hours. You can update it with a simple text editor.
Does this kit need an internet connection to work?
No. All logic runs on the Arduino Mega offline. The RTC maintains schedule time, and the microSD logs data locally. The AI companion only requires internet during the initial build support phase.
What should I do if the CO2 sensor readings seem off?
The AI companion will walk you through the zero‑point calibration procedure for the MH‑Z19B. Place the sensor in fresh air (400 ppm) and run the calibration sketch included in the kit resources.
Meeting Room — Temperature, humidity, CO2 and lux all monitored. Relays control ventilation fan, heater and lighting per flock age schedule.
