This sensor module is made using MQ7, a low cost semiconductor sensor which can detect the presence of carbon monoxide gas at concentrations from 20 to 2000 ppm. The sensitive material used for this sensor is SnO2, whose conductivity is lower in clean air. MQ7 Carbon monoxide gas sensor can be easily interfaced with Microcontrollers,Arduino Boards, Raspberry Pi etc using an Analog to Digital Converter (ADC).
Features
- Low Cost
- High Sensitivity to Carbon monoxide
- Stable and Long Life
- Both digital and analog outputs
- On-board LED indicator
Technical Data
- Operating Voltage : 5V ±0.1
- Operating Temperature : -20°C ~ 50°C
- Detection Range : 20 ~ 2000 ppm of carbon monoxide
Applications
- Domestic gas leakage detector
- Industrial CO detector
- Portable gas detector
