Smart Window Auto-Close Kit with METAR Reports
ESP32 Smart Window Auto-Close Kit with ICAO METAR Weather Reporting
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 monsoon gusts hit unexpectedly or UV levels soar beyond safe limits, this kit automatically closes your windows and simultaneously posts an ICAO-compliant METAR weather observation to your own web endpoint. Powered by an ESP32 and a solar panel, the system reads local sensors every 30 minutes, encodes the data into the standard METAR format, and logs everything to a microSD card - giving you both protection and a professional-grade weather station in one weatherproof enclosure.
What You'll Build
You'll assemble a fully functional, solar-powered window protector that acts as a self-contained METAR-capable weather node. The unit monitors rain, temperature, humidity, pressure, UV intensity, and magnetic window-position (open/closed) in real time. Whenever rain is detected, pressure drops sharply, or UV exceeds a threshold, the system signals a window-close event and transmits the corresponding METAR code to your web server so you can remotely verify conditions.
What You'll Learn
- Encode raw sensor readings into an ICAO-standard METAR string, including temperature, dew point, pressure, and weather groups
- Interface an ESP32 with DHT22, BMP280, ML8511 UV, Hall effect magnetic sensors, and a rain detector
- Implement solar charging with TP4056, deep-sleep power management, and LM2596 voltage regulation for 24/7 outdoor operation
- Post JSON weather data to a custom web endpoint via WiFi and store CSV logs on a microSD card for later analysis

Who This Kit Is For
This kit is built for final-year B.Tech ECE/EEE students, IoT product developers, and weather enthusiasts who need a reliable, solar-powered METAR station. If you're crafting a Smart India Hackathon prototype for weather-responsive infrastructure, a capstone project on wireless sensor networks, or a deployment scenario at IIT/NIT/VIT/BITS, this kit gives you a high-scoring, real-world prototype without the hassle of sourcing and validating dozens of individual components.
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?
Scan the QR code inside the box to launch the AI companion; it knows every connection and code line for this kit. You can also drop a WhatsApp message and our team will reply within a few hours.
Does the kit include the window motor for auto-close?
The kit provides Hall sensors to detect window open/closed state and control logic outputs (via GPIO) to drive a motor. It does not include a 12V DC motor or motor driver - those are easy to source locally and connect using the provided PCB prototype boards.
Can I view the METAR reports online without coding my own web endpoint?
The ESP32 posts the METAR string to any endpoint you configure; we include a sample script for a simple PHP or Node.js server. You can also use free IoT platforms and view the data on your dashboard. The microSD logs serve as a local backup.
Is the system truly weatherproof for rooftop installation?
The included waterproof enclosure (IP65-rated) and the solar panel's sealed junction box protect all electronics. The sensors are placed with cable glands; the enclosure is large enough to house the battery and all modules, making it suitable for permanent outdoor use in Indian monsoons.
Window Protection - Assembles ICAO METAR coded weather report every 30 min from local sensors. Posts to web endpoint.
