Elec-F
Project Background
As factories transition toward Fourth Industrial Revolution technologies, ensuring worker safety in specialized environments like large industrial freezers remains a critical priority. The ELEC-F safety system was developed to prevent hazardous incidents such as freezer entrapment, where efficiency and protection must coexist. Utilizing M5Stack technology, this project provides an automated monitoring solution that tracks personnel presence and door status to ensure that no worker is left at risk. By providing real-time alerts and time-based monitoring, the system offers a robust layer of protection for industrial employees working in high-risk, low-temperature zones.
Design Process
The design process began with identifying the core safety features required to mitigate entrapment risks, specifically focused on detecting both the physical state of the freezer door and human presence. We utilized a hardware-driven planning approach, selecting an M5Stack Fire controller as the central hub to manage inputs from a Time-of-Flight (ToF) sensor for door status and a Passive Infrared (PIR) sensor for motion detection.
To ensure a logical and error-free operation, we utilized a comprehensive flowchart to map the system's behavior. The logic begins with a variable reset followed by a continuous check of the door and interior occupancy. If the system detects a closed door with a person inside, a stopwatch timer starts. If the occupancy exceeds the user-defined time limit, the system triggers a "Warning" state, activating an RGB unit to flash red lights and sounding an M5Stack buzzer to alert nearby personnel.
Role & Impact
As a core member of the development team, I was responsible for translating the conceptual design into a functional hardware model through hands-on prototype fabrication and system assembly. I managed the hardware configuration of the M5Stack controller and sensor modules, ensuring the technical integrity of the system through rigorous debugging and code optimization. To guarantee safety and reliability, I performed extensive testing on the integration of ToF and PIR sensors while leading the documentation process to detail the system architecture and operational workflows for future reference.
