Electronic – arduino – Can Mq4 sensor be used for smoke detection

arduinogas-sensorsensor

I wanted to ask if Mq4 can be used for fire smoke detection?

I read it have small sensitivity to smoke in the data sheet, but I wanted to know what is the least value in ppm for it to detect smoke ?

MQ-4 datasheet

Thanks in advance.

No. This sensor is designed to be primarily sensitive to the components of compressed natural gas -- primarily methane. It is not designed as a smoke detector, and will not reliably respond to the presence of smoke or fire.

If you want to detect smoke, use a smoke detector.
