Description:
The MQ-4 Methane Gas Detection Sensor Module detects Methane gas in the surrounding air. The concentration of methane is output as an analogue voltage reading. This sensor can detect concentrations between 300 – 10000ppm and is suitable for portable gas detectors and home safety automation systems.

The module requires two (2) different voltage inputs to operate. Heater voltage should be 5V (AC or DC) and Loop Voltage should be less than 24VDC.

Specifications:
Size: 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
Gas Detected: Methane
Concentration Sensitivity: 300-10000ppm
Voltage Inputs:
Heater: 5.0V AC or DC, Tolerance: ±0.2V
Loop Voltage: ≤24V DC

Applications:
Suitable for home or factory methane gas, natural gas, and other monitoring devices

Package included:
1 x MQ-4 MQ4 Methane Gas Detection Sensor Module Natural Coal Co for Arduino
