HVAC Performance Monitor Kit v20
HVAC Performance Monitor Kit – Arduino LoRa Solar-Powered Node
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a self-sufficient remote sensor that quietly collects air quality, temperature, humidity, and atmospheric pressure data inside any HVAC duct or room — then packages and transmits it every five minutes via LoRa. This solar-powered node replaces manual inspections with continuous, long-range monitoring suited for energy audits, school science fairs, or B.Tech capstone projects.
What You'll Build
You'll assemble a compact device around an Arduino Nano, MQ-135, DHT22, and BMP280 sensors, all housed in a waterproof enclosure. The RA-02 LoRa module with a 433 MHz antenna sends readings up to several kilometres, while a 6V solar panel and dual 18650 cells keep it running 24/7. The result is a drop-and-forgotten monitor that feeds real data into your own dashboard or cloud platform.
What You'll Learn
- Integrate multiple environmental sensors (MQ-135, DHT22, BMP280) with Arduino Nano on a shared I²C and analog bus.
- Configure and test the RA-02 LoRa module for reliable, low-power data transmission at timed intervals.
- Design a solar charging circuit using the TP4056 module, 18650 cells, and 100 nF decoupling capacitors.
- Write Arduino code that structures sensor payloads into packets and sends them with power saving between transmissions.

Who This Kit Is For
Designed for intermediate learners aged 15-18, this kit maps directly to CBSE Class 11-12 physics and computer science practicals, as well as B.Tech ECE/EEE semester projects. It fits Smart India Hackathon challenges on energy efficiency or smart buildings and can demonstrate IoT and renewable integration in ATL Tinkering Labs across IIT, NIT, VIT, and BITS campuses.
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 kit; you can also send photos via WhatsApp for direct troubleshooting.
Do I need a separate LoRa gateway to receive the data?
Yes, a LoRa receiver module and microcontroller are required on the gateway side. This kit provides the sensor node; pair it with our LoRa Gateway Kit for a complete end-to-end system.
Can this kit run continuously without the solar panel?
The dual 18650 cells alone power the node for about 12-15 hours. The solar panel charges them during daylight, enabling 24/7 operation in most Indian climate conditions.
Is soldering experience required?
Basic soldering is needed to assemble the board. The included soldering iron and step-by-step instructions with practice tips will get you through even if you’re soldering for the first time.
HVAC — MQ-135, DHT22 and BMP280 readings packaged and transmitted via RA-02 LoRa every 5 minutes from solar node.
