Smoke Detectors are very useful in detecting smoke or fire in
buildings, and so are the important safety parameters. In this project, we are
going to build a Simple Smoke Detector Circuit without using any
Microcontroller.
This circuit triggers the Buzzer whenever it detects Smoke or
fire near it. This circuit mainly uses an MQ6 Smoke/Gas sensor to detect the
level of smoke. MQ6 gas sensor is also sensible to LPG, Alcohol, Methane, etc.
Here we have used Buzzer as a Smoke alarm, which is driven by a BC547 NPN
transistor.
We don't support landscape mode yet. Please go back to Portrait mode for the best experience.
