HVAC Performance Monitor Kit – Detect Temperature Anomalies with ESP32 & Z-Score

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

Heating, ventilation, and air conditioning (HVAC) systems hum in the background until something drifts—a clogged filter, a refrigerant leak, or a failing compressor. This kit puts you in control. You’ll build a wireless monitor that continuously samples temperature from a DHT22 sensor, computes a running Z-score baseline, and fires an MQTT alert the moment readings slip beyond three standard deviations—long before equipment damage or energy waste sets in.

What You'll Build

An ESP32-powered HVAC performance monitor that mounts near a vent or chiller line. Green LEDs glow when temperature stays within normal statistical bounds; red LEDs flash and an MQTT publish triggers when the Z-score crosses a configurable threshold. You’ll see exactly how machine-like anomaly detection flags subtle, real-world faults without constant manual checking.

What You'll Learn

• Read DHT22 humidity and temperature data on an ESP32 using Arduino IDE libraries
• Implement a rolling Z-score anomaly detection algorithm in C++ on the ESP32
• Set up a local MQTT broker (Mosquitto) and publish sensor state alerts
• Use bi-colour LED status indicators for in-situ fault signalling

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for CBSE Class 11-12 students tackling IoT in their Skill Subject, ATL Tinkering Lab innovators prototyping predictive maintenance ideas, and B.Tech ECE freshers who want a hands-on sensor analytics project. No prior statistics knowledge is required—the Z-score logic is explained step-by-step in the build companion.

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.
