HVAC Performance Monitor Kit v2
Automate Building Ventilation: HVAC Performance Monitor Kit v2 with Arduino, Light Sensor, and RTC
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 kit lets you build a smart ventilation system that automatically opens louvers at sunrise and closes them at sunset, using real-time light sensing and a precise RTC schedule. Perfect for optimizing airflow in greenhouses, server rooms, or building facades, it also monitors temperature and humidity via the DHT22 sensor. The result is a fully functional HVAC performance monitor that reduces manual intervention and energy waste.
What You'll Build
You'll assemble a weather screen panel with four SG90 servos driving louvers, an Arduino Uno R3 as the controller, and a suite of sensors to detect ambient light (BH1750) and indoor climate (DHT22). The system uses a DS3231 RTC for time-of-day scheduling and an OLED display for live data. Once calibrated, it autonomously manages ventilation based on light levels and time—ideal for capstone projects or smart building prototypes.
What You'll Learn
- Interface I2C modules (BH1750, DS3231, OLED) with Arduino
- Calibrate light thresholds for sunrise/sunset detection
- Program servo-based louver actuation with precise timing
- Design a real-time scheduling system using an RTC

Who This Kit Is For
This kit is designed for advanced engineering students and hobbyists in India—perfect for B.Tech ECE/EEE final-year projects, Smart India Hackathon prototypes, or IIT/NIT/VIT/BITS research labs. If you're building a sustainable building automation system or testing HVAC control algorithms, this pre-assembled kit saves weeks of component sourcing and debugging.
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?
Our AI companion, accessed via QR code, offers step-by-step troubleshooting, and you can reach our support team on WhatsApp for real-time assistance.
Does the kit include the physical louvers and weather screen?
You receive the complete electronics and servos; the mechanical louver structure (plywood, acrylic, or 3D-printed) is supplied by you. We provide 3D printing files and assembly guides in the AI companion.
Can I integrate this with Blynk or IoT cloud platforms?
Yes, the Arduino Uno R3 can connect to a Wi-Fi module (not included) to send data to Blynk or ThingSpeak. The AI companion includes optional IoT integration steps and code snippets.
How do I calibrate the light sensor for sunrise/sunset detection?
You'll take test lux readings at dawn and dusk, then set thresholds in the provided Arduino sketch. The AI companion walks you through the calibration process and provides sample values for Indian conditions.
