This is a very easy-to-use, low cost solid gas sensor module with analog and digital outputs. This module uses MQ2 smoke and flammable gas sensors as gas sensing elements. No external parts required. Just plug in the Vcc and ground pin and you're ready to go.
The
digital output threshold can be easily set using the built-in potentiometer.
This module allows you to easily connect MQ2 smoke and flammable gas sensors to any microcontroller, Arduino and even Raspberry Pi.
This gas sensor module is sensitive to smoke and can be used for fire detection. The MQ2 gas sensor is also sensitive to flammable / flammable gases such as LPG, propane and hydrogen.
Specifications:
- Power Supply: 5 Volts
- Interface Type: Analog & Digital
- High Sensitivity to Smoke & combustible gasses like Hydrogen, LPG & Propane.
- Low Cost.
- Stable & Long Life.
- On board Power indication.
