Smart Home LPG Cylinder Monitor

Liquefied petroleum gas (LPG) cylinders are widely used in home kitchens but can be extremely dangerous and even fatal in the event of an explosion. Monitoring gas cylinder leaks and knowing when to order a refill are critical for safety and convenience. The smart LPG stand, placed under the cylinder, detects leaks from the heavier-than-air LPG gas. It also uses a load cell to measure cylinder weight, indicating when a refill is needed. Additionally, users can access cylinder usage data or enable automatic reordering via optional Bluetooth^® Low Energy (LE) functionality.

System Benefits​:

• Features a low-cost RA2A1 MCU with a built-in op amp, high-resolution ADC (16-bit), and SDADC (24-bit) for precise weight detection. The Arm^® Cortex^®-M23 core MCU and UART option enable seamless data transfer.
• Operates efficiently with a 7.5V battery or isolated AC flyback supply, ensuring long-lasting performance.
• Includes a buzzer for immediate alerts in case of gas leaks, ensuring user safety and security.
