Learn ESP32 Dual Core & FreeRTOS with DHT22 MPU6050 Project Kit
Master FreeRTOS and Dual-Core Programming with DHT22 & MPU6050
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 an IoT environmental monitor that reads temperature, humidity, and motion data on one core while the other core maintains a WiFi connection and pushes data to the cloud via MQTT-all without blocking or delays. This project demonstrates the real difference between single-threaded sketches and true parallel task execution, unlocking the full potential of the ESP32.
What You'll Build
Assemble a breadboard circuit with DHT22 and MPU6050 sensors connected to an ESP32 Dev Board. Program both cores using Arduino IDE and FreeRTOS APIs: Core 0 runs a sensor acquisition loop for temperature, humidity, and accelerometer/gyroscope readings, while Core 1 handles WiFi connectivity and publishes JSON payloads to an MQTT broker. A 0.96-inch OLED displays real-time readings alongside network status, proving that heavy sensor processing never interferes with communication tasks.
What You'll Learn
- Create FreeRTOS tasks and pin them to specific ESP32 cores for parallel execution
- Read DHT22 temperature/humidity and MPU6050 6-axis motion data using I2C protocols
- Implement WiFi and MQTT communication on a dedicated core without blocking sensor loops
- Display live sensor values on a 0.96-inch OLED using the SSD1306 library

Who This Kit Is For
Designed for CBSE Class 11-12 students diving into computer science or electronics, B.Tech ECE/EEE undergraduates prototyping IoT coursework, and participants in Smart India Hackathon or ATL Tinkering Labs who need a reliable dual-core demonstration. If you have programmed an ESP32 before and want to move beyond single-threaded loops to true multi-tasking with FreeRTOS, this kit is built for you.
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 offers immediate diagnostic help for every step; if you need a human hand, WhatsApp support from our Bengaluru team is included.
Can I run this project without a WiFi network for testing?
Yes, the provided code can fall back to a local-only mode where Core 0 displays sensor data on the OLED without MQTT publishing, so you still learn dual-core task assignment.
Do I need prior FreeRTOS experience?
No. The AI companion includes a step-by-step guide that explains FreeRTOS tasks, vTaskDelay, and core pinning from scratch-you'll learn by building.
What can I build beyond the demo project?
Once you've mastered dual-core task handling, expand this kit into a smart home sensor, a drone flight controller with real-time stabilization, or an industrial condition-monitoring node-all on the same ESP32 architecture.
Core 0 runs sensor reading loop. Core 1 handles WiFi and MQTT publish independently using FreeRTOS tasks.
