MQ4 MQ-4 metángáz-érzékelő természetes szén Co-metán detektor modul Arduino

MQ4 MQ-4 Methane Gas Sensor Natural Coal Co Methane Detector Module For Arduino
100% brand new and high quality
FeaturesSize: 32X20X22mm/1.25*0.78*0.86”
The main chip: MQ-4 gas sensing probe
Operating voltage: DC 5V
Power (current) : 150mA
DO Output: 0.1V/5V
AO Output: 0.1-0.3V
Indication of the signal output
Dual signal output (analog output, and TTL level output)
TTL output signal is low. (When low output signal light, and can be connected directly to the microcontroller)
0 ~ 5V analog output voltage, the higher the concentration, the higher the voltage.
Of methane gas, the natural gas has better sensitivity
Applications:
Suitable for home or factory methane gas, natural gas, and other monitoring devicesPackage Included:1 x MQ-4 Methane Gas Sensor Natural Coal Co Methane Detector Module For Arduino
