HVAC Performance Monitor Kit with Arduino Uno – Combine Heat Index and Wind Chill

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Ever wondered why a 30°C day feels like 35°C when it's humid, or why a breeze makes a hot day bearable? This kit lets you build a device that calculates apparent temperature—the temperature your body actually perceives—by combining the DHT22 sensor’s humidity and temperature data with wind speed input. Perfect for understanding HVAC system efficiency, weather science, or just satisfying curiosity about the climate around you.

What You'll Build

You'll assemble a compact monitor with a 16×2 LCD that reads temperature and humidity from the DHT22 sensor, computes the heat index using a well-known algorithm, and optionally accepts a wind speed signal to display wind chill. The final device becomes a practical desktop weather station you can use indoors or even mount outside (with protection) to track real-time apparent temperature.

What You'll Learn

• Wire and read the DHT22 digital temperature/humidity sensor with Arduino Uno.
• Display real-time data on a 16×2 character LCD using an I2C backpack for simpler wiring.
• Program the NOAA heat index formula in Arduino C++ to calculate how humidity affects perceived temperature.
• Understand the wind chill effect and how wind speed modifies apparent temperature (extendable with an external anemometer).
