Automated SYNOP Report Generator
ESP32 SYNOP Report Generator Kit – Automate WMO-Standard Weather Reporting with 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.
Imagine a weather station that not only measures temperature, humidity, pressure, light, and rainfall but also automatically encodes reports in the global WMO SYNOP format and transmits them via LoRa—ready for integration into meteorological networks. Whether you're building for research, disaster monitoring, or a Smart India Hackathon project, this kit delivers.
What You'll Build
A fully autonomous outdoor weather station that captures temperature, humidity, barometric pressure, ambient light, rainfall, and wind speed (via Hall sensors), then generates SYNOP coded messages containing these observations. The system timestamps data with an RTC and logs to a microSD, while a LoRa module sends the report to a gateway up to several kilometres away. The waterproof enclosure ensures deployment in real field conditions.
What You'll Learn
- Interfacing multiple I²C sensors on the ESP32
- Implementing the WMO SYNOP message format in embedded C++
- Configuring and testing the LoRa RA-02 module for long-range transmission
- Designing robust data logging with microSD card and RTC

Who This Kit Is For
This kit is designed for advanced makers and engineers: B.Tech ECE/EEE students tackling final‑year projects, researchers deploying field weather stations, Smart India Hackathon teams working on disaster management, and professionals in meteorological or agricultural IoT. It assumes familiarity with Arduino IDE and basic soldering.
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 on the kit box to access the AI build companion, which can guide you step-by-step. You can also reach us via WhatsApp for direct assistance.
Can I modify the code to add more sensors?
Yes. The firmware is open-source and structured for easy extension. The I²C bus on the ESP32 can accommodate many additional sensors.
Does this kit work with the Indian LoRa frequency plan?
Absolutely. The included RA-02 module operates on 865-867 MHz, the ISM band authorised for LoRa in India. You can configure the frequency in software.
Do I need a separate LoRa gateway, or can I see data directly?
The kit transmits SYNOP reports via LoRa; you’ll need a gateway (such as another ESP32 with a receiver or a commercial LoRa gateway) to receive and display data. The onboard microSD also stores all reports locally.
Collects WMO-standard meteorological parameters and formats them as SYNOP coded messages transmitted via LoRa gateway.
