HVAC Performance Monitor Kit v12
HVAC Performance Monitor Kit v12 – Build a Self-Sustaining LoRa Sensor 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.
Create a fully autonomous HVAC monitoring node that wakes from a 10µA deep sleep every 15 minutes, captures temperature, humidity, and pressure data, transmits it via LoRa over several kilometers, and returns to sleep — achieving up to two years of battery life. Ideal for energy audits, smart buildings, and predictive maintenance in India’s growing commercial infrastructure.
What You'll Build
A weatherproof, solar-rechargeable remote sensor station that continuously logs environmental conditions and sends them wirelessly to a central gateway. You’ll leave behind wiring, frequent battery swaps, and unreliable sensor data — and gain a deploy-and-forget tool for monitoring HVAC health and building efficiency.
What You'll Learn
- Implementing deep-sleep modes on the Arduino Portenta C33 to achieve microamp sleep currents
- Interfacing temperature, humidity, and pressure sensors over I2C and one-wire buses
- Configuring and range-testing LoRa SX1278 modules for long-distance data transmission
- Designing solar charging circuits with TP4056 and 18650 Li-Ion cells for continuous outdoor operation

Who This Kit Is For
This advanced IoT kit is built for B.Tech ECE/EEE final-year students working on low-power wireless sensor networks, participants in Smart India Hackathon tackling smart building or energy challenges, and IoT engineers prototyping long-life remote monitoring for HVAC systems in Indian commercial buildings. If you need to prove energy savings or detect faults before they become failures, this kit delivers a production-grade proof of concept.
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 provides real-time, context-aware guidance, and you can also reach our team on WhatsApp for human assistance within hours.
How do I achieve the advertised 2-year battery life?
The kit includes pre-calculated sleep/wake cycles and power-optimized code; follow the AI companion’s calibration steps and use the supplied solar panel for trickle charging, and you’ll routinely see decades of deep-sleep endurance.
Can I increase the transmission interval or range?
Yes, the LoRa module can be configured for different spreading factors; the AI companion can help you adjust settings for up to 5 km line-of-sight without compromising the power budget.
Is the enclosure truly weatherproof for outdoor installation?
The included IP65-rated enclosure protects against dust and rain; ensure cable glands are properly sealed per the build guide, and the node will survive monsoons and heatwaves.
HVAC — C33 deep-sleep node wakes every 15 min, reads sensors, transmits LoRa and returns to 10µA sleep. 2-year battery life.
