Aquarium Temperature Monitor Kit v2
Build a LoRa Soil Frost Monitoring System with Arduino Nano & ESP32 — Aquarium Temperature Monitor Kit v2
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit empowers researchers, agricultural engineers, and advanced makers to deploy six waterproof DS18B20 temperature sensors at varying soil depths, communicating wirelessly over LoRa to a central ESP32 gateway. By monitoring temperature gradients, you can track frost layer progression precisely — ideal for precision agriculture, permafrost studies, or winter crop management. Unlike individually sourced parts, this kit delivers every component in one box, pre-validated for seamless integration.
What You'll Build
You'll assemble six remote sensing nodes—each built around an Arduino Nano and RA-02 LoRa module—and one ESP32-based gateway that collects and logs temperature readings. The waterproof DS18B20 sensors can be buried at depths from surface to 1 meter, transmitting data every few minutes. The resulting dashboard or serial output shows a real-time temperature profile, enabling you to visualize frost layer advance and retreat over days or weeks.
What You'll Learn
- Circuit design and assembly of low-power LoRa sensor nodes
- OneWire communication protocol for multiple DS18B20 sensors on a single bus
- Configuring RA-02 LoRa modules for long-range wireless data transmission
- Analyzing soil temperature datasets to identify frost line dynamics

Who This Kit Is For
This kit is designed for agricultural researchers, B.Tech ECE/EEE students working on Smart India Hackathon projects, and professionals in precision farming. It's ideal for CBSE Class 11-12 students preparing for ATL Tinkering Lab exhibitions, or IIT/NIT teams developing IoT-based soil monitoring prototypes. The advanced soldering and networking tasks suit experienced makers aged 25+ who are comfortable with PCB assembly and firmware debugging.
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?

How far can the LoRa nodes transmit in typical Indian soil conditions?
The RA-02 modules reliably cover 500 meters in open fields; soil attenuation may reduce range to 200–300 meters. The kit includes 433MHz antennas optimized for ground penetration.
Can I log data directly to a cloud platform?
The ESP32 gateway can be programmed to push data to ThingSpeak or Blynk via WiFi. Sample code for cloud connectivity is included in the AI companion.
Is the DS18B20 sensor truly waterproof for long-term burial?
Yes, each DS18B20 comes in a stainless steel probe with sealed cable jacket, rated for continuous immersion or soil contact over multiple seasons.
