Industrial & household gas tragedy safety system
An AC powered standalone system with smart connectivity using Bluetooth® Low Energy (LE) 5.1 communication to detect the leakage of flammable gas can be a very useful system for industrial and household applications. In this system, a single microcontroller (MCU) with built-in Bluetooth LE communication, DC/DC block and 10-bit ADC aids in quick and easy implementation of a safe system. Additionally, a 1200V built-in bipolar junction transistor (BJT) based AC/DC system can be used for any industrial power line system.
Benefits
- Very high AC operating range with the iW1821 switched-mode power supply (SMPS) IC
- Single MCU + Bluetooth LE 5.1 chip is used for detection and connectivity
- Stand alone, wall mounted system, very small in size and low component count
- Built-in 900V BJT, isolated flyback AC/DC
- LED indication is given for Bluetooth LE connectivity indication
- Buzzer indication for safety/security risk from gas leak
Applications
- Liquefied petroleum gas (LPG) leak detection
- Industrial gas leak detection
