Server Room Temp Monitor Kit - ESP32 LoRa Long-Range IoT
1km-Range Server Room Temperature Monitor Kit v10 (ESP32 LoRa IoT)
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 monitoring your server room's temperature from a kilometre away, without relying on WiFi or cellular data. This kit turns that idea into a working prototype, guiding you to build a LoRa-based sensor node that sends real-time readings to a gateway. It's a ready-made answer for school data centre projects, Smart India Hackathon challenges, or any long-range IoT deployment.
What You'll Build
You'll assemble a compact sensor transmitter using the ESP32, DHT22 temperature-humidity sensor, and RA-02 LoRa SX1278 module. The node reads ambient conditions, packs the data into a LoRa packet, and transmits it on 433 MHz. At the other end, you'll build or configure a receiver gateway that decodes the signal and displays the temperature - exactly the kind of system a real data centre uses to prevent overheating before servers crash.
What You'll Learn
- Interface a DHT22 digital sensor with an ESP32 microcontroller
- Configure and use the RA-02 LoRa SX1278 module for long-range communication
- Program data packet encoding and transmission in Arduino IDE
- Set up a LoRa receiver gateway to decode and display sensor readings

Who This Kit Is For
This kit fits CBSE Class 11-12 students exploring IoT in their computer science elective, B.Tech ECE/EEE undergraduates working on final-year projects, and ATL Tinkering Lab mentors preparing teams for Smart India Hackathon. The wireless sensor network skills you build here map directly onto real-world data centre monitoring, making it a strong addition to any IIT, NIT, VIT, or BITS portfolio.
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 box to launch the AI companion, which walks you through every connection and line of code. If you need a human, reach out via WhatsApp - we'll help you debug.
How far can the temperature data be transmitted?
In open air, up to 1 kilometre. Inside a building with walls and electrical equipment, expect a reliable range of 200-400 metres. The AI companion explains how to optimise antenna placement.
Do I need two kits to set up a complete monitoring system?
This kit contains one transmitter node. To receive data, you'll need an additional ESP32 and RA-02 module as a gateway. The AI companion includes full instructions and code for building the gateway, so you can source a second microcontroller and follow along.
Can this kit be used for Smart India Hackathon or school curriculum projects?
Absolutely. The project aligns with CBSE Class 12 IoT and wireless communication topics, and the long-range temperature alert concept is a common prototype format in hackathons. The skills you learn - LoRa packet handling, sensor integration, and gateway setup - transfer directly to your own IoT innovations.
Data Centre - RA-02 LoRa module on ESP32 sends sensor data to a gateway 1km away without WiFi or cellular.
