Real-Time HVAC Digital Twin Monitor Kit with ESP32 Nodes & Raspberry Pi 5

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

When an HVAC system fails in a server room, pharmaceutical cold chain, or industrial cleanroom, the results can be catastrophic. This kit lets you build a complete monitoring solution - five wireless sensor nodes track temperature, humidity, and vibration on critical HVAC equipment, streaming data to a Raspberry Pi 5 that maintains a live digital twin. If the twin detects an anomaly, it triggers a physical alert, giving you time to act before a real failure occurs.

What You'll Build

You will assemble five ESP32-based sensor nodes, each equipped with a DHT22 for temperature/humidity and an ADXL345 accelerometer for vibration. These nodes communicate over Wi-Fi to a central Raspberry Pi 5, which stores a 3D digital twin model of your HVAC system in real time. A web dashboard displays live metrics, and an onboard alert system (buzzer or LED) activates when the twin detects an abnormal pattern, such as rising vibration or unexpected temperature swings. The entire system is modular - add more nodes later to monitor additional air handlers or duct sections.

What You'll Learn

• Configure ESP32 microcontrollers to read DHT22 and ADXL345 sensors over I2C and one-wire protocols
• Stream real-time sensor data to a Raspberry Pi via MQTT, building a scalable IoT data pipeline
• Create a digital twin using Python on the Pi that models the HVAC operating envelope and detects anomalies with threshold rules
• Set up persistent storage with NVMe SSD and the Pi 5 M.2 HAT+ for data logging and replay
