Features:<\/strong>\n
\u2013 For home or factory gas leakage monitoring devices, suitable for carbon monoxide and other combustible gases and monitoring devices
\n\u2013 High-quality, dual-panel design, with power indicator and TTL signal output instructions;
\n\u2013 DO switching signal(TTL) output and AO analog signal output
\n\u2013 TTL output valid signal is low. (When the output low signal light is on, it can be directly connected microcontroller or relay module)
\n\u2013 Analog output voltage:the higher the concentration,the higher the voltage
\n\u2013 Have better sensitivity to carbon monoxide detector
\n\u2013 Four screw holes,easy positioning
\n\u2013 Product Dimensions: 32 (L) * 20 (W) * 22 (H)
\n\u2013 Long life and stability
\n\u2013 Quick response and resume<\/p>\n
\u2013 Electrical performance:
\n\u2013 Input voltage: DC5V
\n\u2013 Power (current): 150mA
\n\u2013 DO output: TTL digital 0 and 1 (0.1 and 5V)
\n\u2013 AO Output: 0.1-0.3V (relatively clean), the highest concentration voltage is about 4V
\n\u2013 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.<\/p>\n
Specifications<\/strong><\/p>\n
\u2013 Product Model:MQ-9
\n\u2013 Product Type:Semiconduct-gassensitive element
\n\u2013 Gas Detected:Carbon monoxide,Combustible gas
