Sensitive material MQ-6 gas sensors used in clean air, low conductivity Tin Oxide (SnO2).
When there is an environment in which a combustible gas sensor, the conductivity sensor increases with increasing concentration of combustible gases in the air.
Using a simple circuit can convert the change in the conductivity of the gas concentration corresponding to the output signal.
MQ-6 gas sensor for propane, butane, LPG high sensitivity, natural gas and has good sensitivity.
The sensor can detect various flammable gases, it is an inexpensive sensor suitable for various applications.
Using a high-quality two-panel design, with a power indicator and TTL signal output instructions.
Switching signal with DO (TTL) output and AO analog output.
TTL The output signal is low. (Low signal when the output light can be directly connected to the microcontroller or relay module)
Analog output voltage with higher concentration of higher voltage
There are four screw holes for easy positioning.
It has a long service life and reliable stability.
Quick Response and Recovery Feature
Special note: after turning on the sensor, it is necessary to warm up for about 20 s, the measured data were stable, a thermal sensor is normal, because the internal heating wire, if hot is not normal.
- Input voltage: 5VDC
- Operating Current: 150 mA
- Output: TTL digital 0 and 1
- AO Output Range: 0.1 to 0. 3V
- Suitable for home or industrial devices for the detection of liquefied petroleum gas, butane, propane, LNG (liquefied natural gas).
- Excellent resistance to ethanol vapor, fog noise.
