About This

• Input voltage : DC5V Power consumption ( current ): 150mA
• DO output : TTL digital 0 and 1 ( 0.1 and 5V); AO output :0.1-0 .3 V ( relative to pollution ) , the maximum concentration of a voltage of about 4V
• Special note: After the sensor is powered , needs to warm up around 20S, measured data was stable , heat sensor is a normal phenomenon , because the internal heating wire , if hot is not normal .
• Size: 32(L)x20(W)x22(H)mm
• MQ-4 Methane gas sensor of high sensitivity, propane, butane and has a good sensitivity. The sensor can detect a variety of combustible gases, especially natural gas, it is a low-cost sensor suitable for a variety of applications.
