ESP32 HVAC Performance Monitor Kit: Real-Time Data & System Health Dashboard

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

Imagine a monitoring panel that displays not only your room’s temperature and humidity but also the internal health of the microcontroller running the show — updated ten times every second. With this kit, you’ll build exactly that, using an ESP32’s dual-core processor to handle sensor readings and screen refresh simultaneously, all while tracking available memory and WiFi signal strength. It’s a hands-on way to see how a professional HVAC controller manages its own resources while checking the environment.

What You’ll Build

You’ll assemble a compact system that reads the DHT22 sensor for ambient temperature and humidity, then displays these alongside the ESP32’s core utilization (both cores), free heap memory, and WiFi RSSI on a crisp OLED screen. The display updates at 10 Hz, giving you live feedback on both environmental conditions and system load — a practical dashboard for understanding how your HVAC system is performing and how the controller manages its resources.

What You’ll Learn

• Reading digital sensors (DHT22) and parsing environmental data in real time
• Querying ESP32 internal metrics: CPU core usage, heap allocation, and WiFi signal strength
• Driving an OLED display via I2C and updating it at high refresh rates
• Designing a responsive dashboard that juggles sensor acquisition, computation, and display without lag
