ESP32 Roof Leak Detection Kit: Transmit SYNOP Weather Data via LoRa
ESP32 Roof Leak Detection Kit: Transmit WMO SYNOP Weather Data via LoRa
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
For facility managers tired of surprise roof damage, this kit delivers a purpose-built environmental monitor that speaks the language of professional meteorology. Using an ESP32 as the brain, you'll assemble a station that captures temperature, humidity, pressure, light, rainfall, and magnetic door/window states-then encodes everything into WMO-standard SYNOP bulletins and shoots them across kilometres via LoRa. No cloud subscriptions, no proprietary dashboards, just a direct line from your roof to a remote receiver.
What You'll Build
You'll build a compact, weatherproof sensor array that bolts onto roof parapets or gutter edges. Once powered, it reads all environmental inputs every few minutes, timestamps them with the DS3231 RTC, formats a SYNOP message, and transmits it over the RA-02 LoRa module. A companion receiver (not included, but source code provided) can log these messages on a MicroSD card or feed them into existing building management dashboards. The result is early warning of moisture ingress before a leak stains the ceiling, all grounded in meteorological precision.
What You'll Learn
- Interfacing multiple I2C sensors (DHT22, BMP280, BH1750) with ESP32 and managing power-efficient polling
- Encoding environmental observations into WMO FM 12 SYNOP format with proper station identifiers and time groups
- Configuring and transmitting data packets over LoRa using the RA-02 module, including antenna matching and range optimisation
- Deploying a soldered, weatherproofed PCB prototype board inside an enclosure rated for outdoor use

Who This Kit Is For
This kit is built for B.Tech ECE/EEE graduates and M.Tech researchers tackling IoT-enabled infrastructure projects-perfect for Smart India Hackathon teams designing municipal weather monitoring grids. Facility engineers at IIT/NIT campuses or corporate parks will value the SY NOP output for integration with existing BMS platforms, while independent building maintenance contractors can deploy it across multiple client sites without recurring costs.
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 to launch the AI companion-it's trained on this kit's wiring, code, and SYNOP format. For trickier hiccups, WhatsApp support is included.
Can I integrate this with existing building management systems?
Yes. The LoRa receiver output can be parsed into JSON or MQTT on a Raspberry Pi or gateway; we provide Python scripts to forward SYNOP data to common BMS APIs.
What range does the LoRa transmission cover?
In urban environments with the supplied antenna, expect 1-2 km line-of-sight. With an external high-gain antenna and rural clearance, tests have reached 5 km.
Is this kit suitable for outdoor installation?
Absolutely. The waterproof enclosure (IP65) and soldered PCB boards are rated for monsoon exposure. The rain sensor is heated to prevent false readings from condensation.
Building Maintenance - Collects WMO-standard meteorological parameters and formats them as SYNOP coded messages transmitted via LoRa gateway.
