Advanced Greenhouse Monitor Kit - Weight, Humidity & Temperature Logger
Arduino Greenhouse Climate Monitor Kit v2 - Log Weight, Humidity & Temperature for Precision Cultivation
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
You'll build a self-contained greenhouse climate monitor that uses a suspended mesh and load cell to weigh collected water droplets, while simultaneously logging ambient humidity, temperature, and barometric pressure. By correlating these variables, you can quantify condensation rates and optimize irrigation or humidity control in a controlled growing environment.
What You'll Build
After assembling and calibrating this kit, you'll own a data-logging instrument that records water weight, temperature, humidity, and pressure to an SD card, with real-time readout on its OLED display. Use it to study how humidity and temperature swings drive condensation on greenhouse surfaces, or run long-term experiments for agriculture or botany research.
What You'll Learn
- Interface a load cell via HX711 and calibrate for small weight changes
- Read environmental sensors (DHT22, BMP280) over one-wire and I2C protocols
- Timestamp and store sensor data on microSD using an RTC (DS3231)
- Display multi-sensor values on a 0.96-inch OLED and design a menu system

Who This Kit Is For
Engineered for B.Tech ECE, EEE, and Agricultural Engineering students building capstone projects that demand real-time data logging and sensor fusion. It's also a robust choice for Smart India Hackathon teams focusing on precision agriculture, and for IIT/NIT/VIT/BITS researchers needing a reproducible, low-cost environment monitor. The wiring and coding assume prior experience with Arduino IDE and basic soldering.
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?
Start with the AI companion; scan the QR code for annotated wiring diagrams and debugging tips. If you need human help, WhatsApp us - our engineers have built this exact kit.
Can I use this kit for outdoor weather monitoring?
Yes, but the load cell is designed for precise weight measurement in a protected environment. Outdoors, shield the cell from wind and rain, and house the electronics in an IP65 enclosure (not included).
Does the kit include a pre-soldered PCB?
No, you'll solder components onto the provided prototype boards. All schematics and placement guides are included - your AI companion walks you through each connection.
How long can it log data?
With a standard 8GB microSD card, it logs over a year of data at 10-second intervals. Data is stored as CSV for easy import into any spreadsheet or analysis tool.
