Mining Safety Collar Tag Kit with ESP32 & LoRa
Build a Mining Safety Collar Tag with ESP32 & LoRa - Classify Movement, Send Alerts
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
In underground mining, knowing a worker's activity state can prevent accidents. This kit lets you build a battery-powered collar tag that uses an ADXL345 accelerometer to classify movements like grazing, walking, resting, and running, then transmits event counts via long-range LoRa to a gateway. Perfect for industrial safety projects, hackathons, and electronics labs.
What You'll Build
A functional mining safety collar tag that monitors movement patterns, logs data to a microSD card, and transmits real-time activity summaries over LoRa. You'll prototype the complete sensor node that could be deployed in a mine to track worker behaviour, integrating motion sensing, wireless communication, and low-power design.
What You'll Learn
- Interfacing an ADXL345 accelerometer and reading raw acceleration data
- Implementing activity classification algorithms (resting, walking, running, grazing) on ESP32
- Setting up LoRa communication with RA-02 SX1278 and 433MHz antenna
- Designing a low-power wearable system with LiPo battery and charging module

Who This Kit Is For
This kit is ideal for B.Tech ECE/EEE students working on IoT-based safety systems, Smart India Hackathon teams building mining solutions, and CBSE Class 11-12 students exploring wearable electronics. ATL Tinkering Labs can use it for advanced sensor projects, and hobbyists interested in LoRa communication will find it a hands-on learning tool.
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 - it's trained on this exact project and can troubleshoot common wiring or code issues. You can also reach us on WhatsApp for direct guidance.
How does the collar tag detect different activities like grazing or running?
The ADXL345 accelerometer captures motion data; we provide sample code that classifies patterns based on acceleration magnitude and orientation changes, distinguishing resting, walking, running, and grazing (low bending movements).
Can I modify this kit for other LoRa applications?
Absolutely. The ESP32-S3 and RA-02 module form a flexible LoRa node that you can reprogram for environmental monitoring, wireless data logging, or any long-range IoT project.
What range can I expect from the LoRa communication?
With the included 433MHz antenna and proper line-of-sight, the RA-02 module can achieve several hundred meters indoors and up to a few kilometers outdoors in open areas. The gateway setup guide helps you extend range further.
Mining Safety - ADXL345 collar tag classifies grazing, walking, resting, running. LoRa transmits event counts to gateway.
