Greenhouse Rain Logger Kit - WMO SYNOP Weather Station via LoRa
Greenhouse Rain Logger Kit - Build a WMO-Standard SYNOP Weather Station with ESP32 and 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.
Transform your greenhouse into a professional meteorological monitoring station that generates WMO-standard SYNOP coded messages. This advanced kit lets you measure rainfall, temperature, humidity, pressure, and light, then format and transmit observation codes over a LoRa gateway - exactly as national weather bureaus do for synoptic data exchange.
What You'll Build
A rugged, self-contained weather station that logs rainfall events, ambient conditions, and even magnetic door states. It encodes all data into FM 12 SYNOP bulletins and sends them via long-range LoRa radio. The system runs autonomously with a real-time clock and logs to microSD for backup, making it ideal for precision agriculture and greenhouse automation where standards-compliant data matters.
What You'll Learn
- Assemble and calibrate a multi-sensor meteorological payload including rain gauge, temperature/humidity, barometric pressure, and light sensors
- Encode sensor readings into WMO FM 12 SYNOP format with correct code figures, groups, and station identification
- Configure and transmit data packets using the RA-02 LoRa module and a 433MHz antenna for long-range, low-power communication
- Use a real-time clock (DS3231) and microSD module to create a time-stamped, autonomous weather archive with zero data loss

Who This Kit Is For
Ideal for advanced makers, agricultural engineering students, and researchers who need a standards-compliant weather data pipeline. This kit directly supports B.Tech ECE/EEE capstone projects on precision farming, Smart India Hackathon participants building agri-tech prototypes, and ATL Tinkering Lab mentors designing demonstration weather networks. Basic embedded programming experience is assumed.
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?
The AI companion offers a full walkthrough; you can also send a WhatsApp message with photos of your setup. We respond within hours to help debug specific issues like sensor calibration or SYNOP group formatting.
Do I need prior experience with LoRa or SYNOP encoding?
Familiarity with Arduino IDE and basic electronics is assumed. The AI companion explains SYNOP encoding step-by-step, and you'll configure the RA-02 module using pre-built libraries-no prior LoRa experience required.
Can I use this kit with an existing LoRaWAN gateway?
The RA-02 can be configured for LoRaWAN, but the included firmware demonstrates point-to-point LoRa to a custom receiver. You can adapt the code for TTN or ChirpStack-the AI companion provides guidance on gateway integration.
Is the rain sensor calibrated to WMO standards?
The included tipping-bucket sensor provides per-tip data; the firmware converts tip counts to mm following WMO methods for rainfall measurement. A calibration guide inside the kit ensures accuracy for meteorological reporting.
Greenhouse - Collects WMO-standard meteorological parameters and formats them as SYNOP coded messages transmitted via LoRa gateway.
