Smart Home Liquefied Petroleum Gas (LPG) Cylinder Monitor

LPG cylinders can be very dangerous and even fatal if they explode so monitoring for gas cylinder leakage is critical. Renesas' LPG is a heavier-than-air gas, and the smart LPG stand placed under the cylinder can easily detect gas leaks. In addition, weight detection is performed using a load cell, indicating when a refill is needed. Users can even access the cylinder usage data or enable automatic reordering by accessing the optional Bluetooth® Low Energy (BLE) functionality.

Features and Benefits
