HVAC Performance Monitor Kit v17
Monitor Every Breath Your AC Takes — Build a Live HVAC Dashboard with This ESP8266, DHT22 & BMP280 Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
When the air feels stuffy or your power bill climbs, it’s hard to know if your HVAC is working right. This kit lets you build a Wi‑Fi monitor that captures temperature, humidity, and barometric pressure — then shows everything on a web page you open from any device at home. In a couple of hours you’ll have hard data to judge your air conditioner, heater, or dehumidifier’s real output, and you can tweak settings for comfort and savings.
What You'll Build
You’ll wire a DHT22 temperature/humidity sensor and a BMP280 pressure sensor to an ESP8266 NodeMCU. The ESP runs a tiny web server you access over your home Wi‑Fi. Every reading appears as a live numeric display and a chart — temperature in °C, humidity in %, and pressure in hPa. Place the monitor near an air vent or in a room you want to track; within minutes you’ll spot patterns like overcooling, poor circulation, or humidity spikes.
What You'll Learn
- Connecting multiple I²C and one‑wire sensors to a microcontroller
- Reading temperature and humidity from a DHT22 with a 4.7kΩ pull‑up resistor
- Fetching barometric pressure and altitude‑derived data from a BMP280
- Hosting a responsive web dashboard on the ESP8266 without external hosting

Who This Kit Is For
Young innovators from age 5 (with adult help) up to CBSE Class 11‑12 students working on physics or computer science projects will find this kit a perfect match. ATL Tinkering Lab participants building IoT‑based climate monitors and B.Tech ECE/EEE freshers who want a gentle introduction to ESP8266 web servers will also love the guided experience. No prior soldering or coding background is needed — the hardware plugs together on a breadboard, and the AI companion explains every step in plain language.
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 will walk you through the exact wiring and code step by step; you can also send a photo on WhatsApp and our team will guide you personally.
Do I need to know programming?
Not at all. The ESP8266 comes with pre‑loaded code, and the wiring is fully documented. The AI companion explains what each line does so you learn as you build.
Can I see the readings when I’m not at home?
The default web dashboard works only on your local Wi‑Fi. If you want remote access later, you can extend the project with a free cloud service like ThingSpeak — the kit gives you a solid foundation to start.
Is the kit safe for a 5‑year‑old?
All connections use 3.3V or 5V from a standard USB power source — there’s no mains electricity. Adult supervision is recommended for children under 10, but everything is plug‑and‑play with no sharp tools required.
HVAC — ESP8266 reads DHT22 and BMP280 and displays live readings on local web page.
