Specifications
Product Model:MQ-9
Product Type:Semiconduct-gassensitive element
Gas Detected:Carbon monoxide,Combustible gas
Detectable Concentration:10-1000ppmCO, 100-10000PPM gas

Instructions;
DO switching signal(TTL) output and AO analog signal output
TTL output valid signal is low. (When the output low signal light is on, it can be directly connected microcontroller or relay module)
Analog output voltage:the higher the concentration,the higher the voltage
Have better sensitivity to carbon monoxide detector
Four screw holes,easy positioning
Product Dimensions: 32 (L) * 20 (W) * 22 (H)
Long life and stability
Quick response and resume

Electrical Performance:
Input voltage: DC5V
Power (current): 150mA
DO output: TTL digital 0 and 1 (0.1 and 5V)
AO Output: 0.1-0.3V (relatively clean), the highest concentration voltage is about 4V

Special Note:
When the sensor is powered, it needs to be warmed up about 20S, so the measured data becomes stable, the heat sensor is a normal phenomenon, because its inside is with an electric wire, if not, unnomal.

Package Include:
1x MQ9 Module

Electrical Parameters
Voltage DC 5V
Current 150mA
Physical Parameters
Size 32mm x 20mm x 22mm
