Greenhouse Climate Monitor Plus Kit with Arduino Uno + DHT22
Build a Greenhouse Climate & Swarm Detection System with Arduino Uno + 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.
This advanced kit lets you build a smart greenhouse monitor that not only tracks temperature, humidity, and sound but also weighs a beehive in real-time. By logging weight data to an SD card, you can detect a swarm event—a sudden drop in weight as bees leave—and trigger an alert. Perfect for agriculture students and IoT enthusiasts exploring precision farming, the system gives you the tools to study hive health without opening the hive.
What You'll Build
A self-contained environmental monitor for a greenhouse beehive. It continuously records internal hive temperature (via two DS18B20 probes), ambient humidity (DHT22), sound levels (MAX4466 microphone), and the precise weight of the hive (HX711 + 20kg load cell). The 0.96-inch OLED screen shows live readings, and all data is time-stamped using a DS3231 real-time clock and saved to a microSD card. By programming a weight drop threshold, the system can identify a potential swarm and log the event for later analysis.
What You'll Learn
- Integrating multiple I2C and one-wire sensors on a single Arduino bus without conflicts
- Implementing SD card data logging with precise timestamps from an RTC
- Calibrating a load cell with HX711 for accurate weight measurement over time
- Designing a threshold-based event detection algorithm that combines weight and sound data to predict swarming

Who This Kit Is For
This kit is ideal for B.Tech ECE/EEE students working on agricultural IoT projects, Smart India Hackathon teams tackling precision beekeeping, and researchers at IITs, NITs, and agricultural universities developing low-cost hive monitors. If you're building a final-year project around smart farming or swarm intelligence, this kit provides a complete, calibrated system out of the box, ready for data collection and analysis.
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 chat with the AI companion trained on this exact circuit. It can walk you through wiring, code debugging, and calibration. WhatsApp support is also available for complex issues.
Can this kit detect a swarm accurately?
Yes. By monitoring weight drops above a threshold and combining with a sudden increase in sound level from the microphone, you can reliably flag swarm events. The AI companion includes guidance on tuning the thresholds based on your specific hive.
Is the waterproof enclosure suitable for outdoor hive placement?
The included enclosure is IP65-rated, protecting the electronics from rain and dust. Sensor probes can be routed through sealed grommets, keeping the internal components safe while allowing accurate hive measurements.
Can I add remote monitoring via WiFi to see data online?
The kit focuses on local SD logging, but the Arduino Uno can be paired with an ESP8266 module (not included) to push data to the cloud. The AI companion includes wiring diagrams and sample code to add this expansion.
Greenhouse — HX711 weight, DS18B20 internal hive temp, humidity and sound level logged to SD. Detects swarm event by weight drop.
