HVAC Performance Monitor Kit v9
HVAC Performance Monitor Kit v9 — LoRaWAN Sensor Node for The Things Network
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Deploy a battery-powered LoRaWAN sensor node that monitors temperature, humidity, and barometric pressure at HVAC intake and exhaust points. View decoded payloads in real-time on The Things Network console, and integrate the data stream into building management systems or dashboards. This kit is built for professionals who need reliable, long-range environmental monitoring without Wi-Fi dependency.
What You'll Build
You’ll assemble a robust, waterproof-enclosed sensor node powered by an Arduino Nano and RA-02 LoRa module. The DHT22 and BMP280 sensors capture accurate environmental data, which is transmitted over LoRaWAN using OTAA join to TTN. On the console, you’ll see decoded, human-readable payloads of temperature, humidity, and pressure, ready for downstream applications.
What You'll Learn
- Design and program a LoRaWAN end-device using Arduino and the SX1278 chipset
- Configure Over-The-Air Activation (OTAA) and securely join The Things Network
- Integrate DHT22 and BMP280 sensors and package data into efficient binary payloads
- Decode LoRaWAN payloads on the TTN console using JavaScript payload formatters

Who This Kit Is For
Engineers and facility managers deploying IoT in HVAC systems, B.Tech ECE/EEE students working on final-year industrial IoT projects, and professionals from IITs, NITs, and VITs implementing LoRaWAN-based monitoring. The kit also fits industrial training programs and smart building hackathons like Smart India Hackathon, where reliable wireless telemetry is critical.
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?
The AI companion covers every step, from wiring to payload decoding. If you need live help, our WhatsApp support is available for direct debugging assistance.
Do I need an existing TTN gateway to test this kit?
The kit works with any TTN-compatible gateway within range. If you don’t have one, we recommend the TTN Indoor Gateway or using a community gateway mapped on the TTN console.
Can I modify the payload format to send additional sensors?
Yes. The AI companion includes code snippets to add more I2C sensors and adjust the binary payload bytes, along with updated JavaScript decoder scripts for TTN.
Is the waterproof enclosure suitable for outdoor HVAC duct mounting?
Absolutely. The IP65-rated enclosure protects the electronics from dust and water jets. Mount it on an air handling unit, ensuring the antenna is externally routed for optimal LoRa range.
