The leakage of liquefied petroleum gas may pose a threat to life, even if the concentration is low, it can make people suffocate; and when the concentration is high enough, it can also cause fire or explosion.

The other is that higher concentrations of carbon dioxide can cause respiratory problems, and long-term exposure to it can lead to death.

So, useGas sensormonitoring and early warning of liquefied petroleum gas and carbon dioxide concentration is very important.

All sensing systems consist of these two parts: a sensing element for measuring one or more electrical parameters such as resistance and capacitance, and a circuit for measuring changes in these parameters. Most of these sensors can operate on batteries, so they can work continuously for several years. Therefore, reducing their operating power consumption is the general trend.
