Greenhouse Climate Monitor Kit with Arduino – Build a Menu-Driven Environmental Control System to Protect Your Plants

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Whether you're a greenhouse hobbyist in Kerala monitoring delicate orchids or a student prototyping an agri-tech solution for a college competition, this kit equips you with a smart climate monitor that does more than just read sensors. The 5-button menu system lets you set temperature and humidity thresholds, view historical min/max values, and control a relay to activate fans, heaters, or misters automatically. Best of all, the entire code is written in reusable C modules — you can drop the same menu library into your next project without starting from scratch.

What You'll Build

You'll assemble a fully functional greenhouse monitor on a breadboard. The LCD displays real-time temperature and humidity from the DHT22. Five tactile buttons let you navigate multi-level menus: a live monitoring screen, threshold settings, min/max records, and relay control. When the sensor readings cross your set limits, the relay activates, giving you automated environmental control. The circuit and code are documented with enough detail that you can expand the system later — add a soil moisture sensor, a real-time clock, or an SD card logger without rewriting the core menu.

What You'll Learn

• Integrate the DHT22 temperature and humidity sensor with Arduino and display data on a 16x2 LCD via I2C in clear, readable format.
• Implement a multi-level menu system using five tactile buttons for navigation, selection, and threshold adjustment — a skill that transfers to any embedded project with a display.
• Control a 5V relay module to switch external devices based on sensor thresholds, enabling automatic fan, heater, or pump activation in greenhouses or labs.
• Write modular, reusable C code that separates menu logic from hardware control, so you can adapt the same structure to weather stations, smart home dashboards, or incubators.

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is designed for CBSE Class 11–12 students building electronics projects for practical exams, B.Tech ECE/EEE students working on embedded C assignments, and ATL Tinkering Lab participants developing agri-tech prototypes for competitions like Smart India Hackathon. If you're at IIT, NIT, VIT, or BITS Pilani and need a ready-to-assemble system with reusable code for a mini-project, this kit removes the guesswork — you'll spend your time building and learning, not hunting for compatible parts.

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.
