HVAC Performance Monitor Kit v7 — Real-Time Climate Alerts with ESP8266, DHT22 & Blynk

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 a server room gets too hot or a greenhouse drops below safe humidity, a delayed alert can mean damaged equipment or wilted crops. This kit puts that alert in your pocket — you’ll build a live environmental monitor that streams temperature, humidity, and light readings to a custom mobile dashboard and instantly notifies you the moment conditions cross a boundary. It’s a real-world IoT tool that teaches the same concepts used in smart buildings and automated climate control.

What You'll Build

By the end of this project, you’ll have a fully soldering-free device that reads temperature and humidity from a precision DHT22 sensor, detects ambient light through two LDRs, displays live values on an OLED screen, and pushes all data to a Blynk dashboard on your phone. The system actively watches for threshold breaches — too hot, too cold, or sudden light changes — and sends an instant push notification. Think of it as a smart thermostat that doesn't just react, but warns you before conditions become critical.

What You'll Learn

• Connect and program an ESP8266 NodeMCU to interface with a DHT22 digital temperature/humidity sensor
• Read analog LDR signals to measure ambient light and translate them into actionable data
• Stream multi-sensor data to the Blynk IoT platform and design a live mobile dashboard
• Code threshold logic to trigger mobile push notifications based on real-time sensor readings

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for intermediate builders aged 15 and above, this kit fits perfectly into CBSE Class 11–12 electronics projects, B.Tech ECE/EEE coursework, and Smart India Hackathon prototypes. ATL Tinkering Lab mentors will find it a ready-to-deploy environmental monitoring module, while IIT, NIT, VIT, and BITS Pilani students can use it to demonstrate cloud-connected sensor systems and threshold-based automation.

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.
