Server Room Temperature Monitor Kit v3
Server Room Temperature Monitor Kit v3 — Decode RS41 Radiosonde Signals from the Upper Atmosphere
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
What if your server room climate control could anticipate shifts in external temperature and humidity by analysing data from the upper atmosphere? This kit transforms a set of sensors, an Arduino Mega, and a directional Yagi antenna into a deployable radiosonde decoding system. Capture 433 MHz RS41 transmissions from weather balloons, extract GPS-synced profiles of temperature, pressure, humidity, and wind, and use that knowledge to fine-tune data centre environmental management around the clock.
What You'll Build
You will assemble a portable field receiver that locks onto radiosonde telemetry, decodes the RS41 data stream through the Arduino, and correlates it with precise location and timestamp from the NEO-6M GPS and DS3231 RTC. Live readings and decoded profiles appear on the 0.96-inch OLED, while every data packet saves to a microSD card for later analysis. The directional Yagi antenna gives you the gain needed to follow a balloon from launch to burst, mapping the atmospheric layers above your site.
What You'll Learn
- How to aim a directional Yagi antenna and maximize signal-to-noise ratio for 433 MHz data links
- The RS41 digital protocol structure and real-time decoding on Arduino Mega
- Synchronising sensor readings with GPS position and RTC timestamps for accurate profiling
- Logging and visualising radio-silence gaps to reconstruct wind vectors between GPS fixes

Who This Kit Is For
B.Tech ECE and EEE students crafting atmospheric monitoring entries for Smart India Hackathon, meteorology hobbyists who want to learn radiosonde decoding, and IoT engineers building custom environmental profilers. If you are working from a NIT, VIT, BITS, or IIT lab and need a ready-to-assemble kit that reduces RF project setup time, this version three kit eliminates the guesswork.
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?
Open the AI companion from the QR code on the box, or drop us a WhatsApp message. It knows your kit’s wiring, scripts, and common mishaps — including how to orient the Yagi for first signal lock.
Do I need an RTL-SDR dongle or Raspberry Pi to decode radiosonde signals?
The kit includes all sensors, data logging, and the directional antenna. Radiosonde signal reception requires an additional RTL-SDR dongle and a Raspberry Pi (or laptop) running decoder software. The AI companion walks you through integrating them with the Arduino logger.
Can this kit work as a standalone weather station without radiosonde tracking?
Absolutely. Disconnect the antenna and the Arduino will log GPS-timestamped temperature, humidity, and pressure from the BMP280 and DHT22 to the microSD card, with live readings on the OLED. Perfect for long-term site climate recording.
What is the effective range of the directional Yagi antenna for radiosonde signals?
With line-of-sight to a high-altitude balloon, the antenna can lock onto signals from over 300 km. Its forward gain and narrow beamwidth help reject ground noise, making it ideal for chasing a descending sonde.
Data Centre — RTL-SDR dongle + Raspberry Pi + Arduino receive and decode RS41 radiosonde signals to reconstruct upper atmosphere profiles.
