HVAC Performance Monitor Kit v28
HVAC Performance Monitor Kit v28 — Arduino-Based LoRa Sensor Network for HVAC Monitoring
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn an Arduino Nano into a wireless HVAC monitoring node that transmits DHT22 sensor data via RA-02 LoRa modules over 433MHz. Set up a gateway that displays readings on an OLED screen, then experiment with transmission power levels to map real-world range limits — exactly the kind of hands-on test engineers do when designing building automation systems.
What You'll Build
From this kit, you'll assemble two independent Arduino Nano nodes: one battery-powered sensor node that reads temperature and humidity, and one USB-powered gateway node that receives the data wirelessly and shows it on the OLED. You'll be able to place the sensor at different distances, adjust the LoRa module's transmission power via software, and observe how signal range changes — giving you a practical understanding of wireless propagation in indoor environments.
What You'll Learn
- How to configure and communicate between two Arduino boards using LoRa
- Reading and decoding temperature/humidity data from a DHT22 sensor
- Controlling transmission power on RA-02 LoRa modules and measuring its effect on signal range
- Displaying real-time sensor data on an OLED screen with an Arduino

Who This Kit Is For
This kit is designed for students and hobbyists serious about IoT and wireless communication. Ideal for CBSE Class 11-12 AI/ML or physics projects, B.Tech ECE/EEE mini-projects, Smart India Hackathon teams prototyping sensor networks, and ATL Tinkering Lab mentors guiding advanced experiments. If you're at an IIT, NIT, VIT, or BITS Pilani working on an HVAC telemetry proof-of-concept, this kit gives you a real hardware baseline.
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 open the AI build companion, pre-trained on this kit. It walks you through code uploads, wiring, and troubleshooting. If you need more help, WhatsApp us for a direct response within a few hours.
Do I need to solder any components?
No, all connections are made with pre-cut jumper wires and half-size breadboards. You only need a USB port to program the Arduino Nanos.
Can I view sensor data remotely without the OLED?
The gateway displays readings locally, but you can also modify the code to forward data to your laptop via serial, or connect an external display. The AI companion includes tips for adding serial output.
What if my 18650 battery runs out quickly?
The sensor node is designed for low-power LoRa transmission when idle. You can further extend battery life by adjusting transmission intervals in the code, a technique covered in the companion's optimization guide.
HVAC — RA-02 LoRa module sends DHT22 data from sensor node to gateway node — measure range vs transmission power.
