OLED Dual Core Task Monitor Kit with ESP32 + LED
ESP32 Dual Core Task Monitor Kit – Visualize CPU Load, Free Heap & WiFi RSSI in Real Time
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
You'll build a compact, performance dashboard that reads the ESP32's internal diagnostics — CPU load on both cores, free heap memory, and WiFi signal strength (RSSI) — and updates them on a crisp OLED display 10 times per second. It’s the perfect way to understand dual-core task management in FreeRTOS or to embed system-monitoring logic into your own IoT projects.
What You'll Build
A fully functional ESP32-based monitor that displays dual-core CPU usage, available memory, and WiFi connectivity on a 0.96-inch OLED. The code samples internal performance counters and draws live graphs and numeric readouts at 10 Hz, giving you smooth, real-time feedback. Included in the kit is a DHT22 temperature and humidity sensor — once you’ve mastered the core project, you can extend the dashboard to show environmental data as well, turning it into a complete IoT monitoring station.
What You'll Learn
- Reading ESP32 internal performance counters to measure dual-core CPU load
- Displaying real-time data on an I2C OLED with live graphs and numeric overlays
- Managing FreeRTOS tasks to run independent sampling and updating loops simultaneously
- Interpreting WiFi signal quality (RSSI) and free heap memory to debug IoT reliability

Who This Kit Is For
Designed for intermediate makers ready to go beyond blinking LEDs. CBSE Class 11-12 students exploring IoT and embedded systems, B.Tech ECE/EEE students building data-acquisition projects, and Smart India Hackathon participants who need a real-time system monitor. Also a natural fit for ATL Tinkering Lab sessions on performance analytics and dual-core programming.
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 gives interactive, step-by-step help for this exact kit. You can also send a WhatsApp message for live support from our team.
Can I display other metrics besides CPU load and WiFi RSSI?
Absolutely. The ESP32 exposes many internal variables (like task watermarks, uptime, core temperature). The companion will guide you through modifying the code to show custom metrics on the OLED.
Is the DHT22 sensor used in the base project?
It’s optional. The core monitor runs without it. If you want to add temperature and humidity readings later, the companion provides an extended tutorial to integrate the DHT22 seamlessly.
How clear is the OLED display for a lab desk?
The 0.96-inch I2C OLED delivers high contrast and a wide viewing angle. It’s perfectly readable indoors, even in well-lit classrooms or workshops.
ESP32 shows CPU load of both cores, free heap and WiFi RSSI on OLED updated 10 times per second.
