MQ-2 MQ2 Gas Sensor Module For LPG Propane Hydrogen Arduino Raspberry Pi

£3.25

MQ-2 Smoke methane gas liquefied flammable gas sensor module for Arduino Raspberry Pi

This sensor is used for the detection of any leakage in gas. The sensor is suitable for the detection of methane, butane, propane.  The sensor is sensitive for flammable and combustible gasses.

1. the heating voltage : 5 + 0.2V (AC . DC)
2. Working current : 150mA
3. the circuit voltage : < DC15V (Max DC15V)
4. the load resistance : 1K ( adjustable )
5. the detection concentration range :100-20000ppm ( concentration range of different gases differ )
6. clean air voltage : < 1.5V
7. Sensitivity : > 3%
8. response time : < 1S (preheat 3-5 minute  )
9. response time : < 30S
10. the component power consumption : < 0.9W
11. Working temperature : -10 ~ 50 C ( nominal temperature 20 C)
12. Humidity : 95% RH ( nominal humidity 65% RH)
13. size : 35mm × 22mm × 25mm
14. weight Size : 7g
15. dual signal output ; ( analogue output , and TTL level output )
16 .TTL output valid signal is low , which can be accessed directly connected to the micro controller IO port
17. 0 ~ 5V analogue output voltage , the higher the concentration the higher the voltage 
18. the gas, butane , methane , smoke, etc. have better sensitivity 
10. long life , good stability 
20. with fast response and recovery characteristics
