ESP32 HVAC Monitor Kit: Dual-Core FreeRTOS Project for Teens
Master ESP32 Dual-Core with a Professional HVAC Monitor 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.
Turn a bare ESP32 into a split-brain HVAC sentry. Core 0 runs a relentless sensor loop, grabbing humidity, temperature, and vibration data with microsecond precision. Core 1 stays locked on WiFi and MQTT, shovelling telemetry to your broker without ever interrupting the readings below. You end up with a device that behaves like a real industrial monitor - a perfect project for anyone who wants to understand how modern embedded systems truly multitask.
What You'll Build
A self-contained environmental monitor that logs room climate and equipment vibration on a bright OLED while publishing wirelessly to an MQTT broker you control. You will assemble the circuit on a breadboard, flash the firmware, and then watch the two ESP32 cores operate independently - one handling the DHT22 and MPU6050 sensors, the other managing network connectivity. By the end, you hold a ready-to-deploy prototype for energy audits, server-room monitoring, or just proving to your professor that RTOS concepts aren't just textbook theory.
What You'll Learn
- Create independent FreeRTOS tasks to separate sensor reading from WiFi/MQTT communication on a dual-core ESP32
- Interface DHT22 and MPU6050 sensors and read temperature, humidity, and vibration data inside Core 0's loop
- Publish real-time HVAC telemetry to an MQTT broker from Core 1 without clocking the main sensor cycle
- Drive a 0.96-inch OLED display over I2C to show live environmental stats with zero lag

Who This Kit Is For
CBSE Class 12 students who need a standout IoT project for their final evaluation, first-year B.Tech ECE/EEE learners encountering RTOS for the first time, and Smart India Hackathon teams that want a reliable dual-core sensor gateway without breadboarding from scratch. If you have spent an afternoon blinking an LED and are ready to see how a real-time operating system splits a microcontroller's brain, this kit meets you exactly where you are.
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.
Do I need prior experience with FreeRTOS or dual-core programming?
No. The AI companion walks you through task creation, pin assignments, and MQTT configuration step by step. If you prefer a human touch, our WhatsApp support team can clarify concepts within minutes.
Can I run this project entirely on the Arduino IDE?
Absolutely. The provided code compiles under the Arduino framework with the ESP32 board package. The AI assistant will help you configure the correct board settings and required libraries.
What happens if my WiFi goes down while the HVAC monitor is running?
Core 0 continues reading sensors and updating the OLED without interruption. Core 1 will attempt automatic reconnection and resume MQTT publishing once the network returns - a self-healing pattern you can study and reuse in your own designs.
Can I log the sensor data without running my own MQTT broker?
Yes. The AI companion includes instructions for connecting to free public brokers during prototyping, and the code can be adapted to services like ThingSpeak or Adafruit IO with minor changes.
HVAC - Core 0 runs sensor reading loop. Core 1 handles WiFi and MQTT publish independently using FreeRTOS tasks.
