Is the sensor of natural gas alarm good for semiconductor gas sensor or catalytic sensor?

Semiconductor gas sensors are gas sensors that utilize semiconductor gas sensors as the sensitive element, and they are the most common gas sensors, widely used in combustible gas leakage detection devices in homes and factories for detecting methane, liquefied petroleum gases, hydrogen, etc. The catalytic combustion sensor principle is one of the most widely used principles for detecting combustible gases.

The catalytic combustion sensor principle is one of the most widely used principles for detecting combustible gases, featuring good output signal linearity, reliable index, low price, and no cross-interference with other non-combustible gases.
