GasVisor: Smart IoT Solution for Gas Cylinder Monitoring

GasVisor, an IoT device on the nRF9160 platform, monitors gas cylinders in real-time, tracking weight, temperature, humidity, and CO2 with remote updates.

Designing: THE MACHINE’S
Unique
Architecture

The design and development encapsulates following process

  • Embedded System Architecture
  • 4 Different Sensors Integration
  • Communication Modules Implemented
  • RTC Wake & Duty Cycles
  • Energy-efficient E-Ink display
  • Two-point Factory Calibration
  • Firmware Development Phase
  • Secure Transmission & OTA Updates
  • Remote Monitoring & Control
  • Voltage Monitoring & Sleep Schedules
  • Audible Alerts & Safety Features
  • Rugged Chanical Design

Engineering Challenges:
How We Overcame Them?

Overcame design, power, and integration challenges with
innovative solutions and optimized engineering.

Power Optimization
Implemented deep sleep and RTC-based wakeup routines for extended battery life.
Network Connectivity
Adapted signal strength configurations dynamically for optimal LTE communication.
Accurate Measurement
Fine-tuned calibration routines and tare mechanisms to improve precision.
Menu Navigation Usability
Developed an intuitive button-based interface with timeout mechanisms to simplify user interaction.

Prototype Development

The GasVisor was meticulously developed to bring the conceptual design to life while ensuring practical functionality and performance.

Integration Phase

This phase ensured seamless communication between embedded firmware and sensors, validating accurate data acquisition. Connectivity tests for NB-IoT/CAT-M, GNSS, and MQTT were conducted to guarantee stable network performance and real-time cloud communication.

Testing Phase

Power consumption was analyzed by optimizing sleep cycles and RTC wake mechanisms for extended battery life. The user interface was tested for intuitive menu navigation, while security testing focused on encryption and authentication for secure OTA updates and data transmission.

Innovative Directions:
Possible Future Enhancements
