商品情報商品の説明MQ-3 gas sensor is sensitive material used in clean air, low conductivity tin dioxide (SnO2). When the sensor is present in the environment in which the alcohol vapor, the sensor's conductivity increases with the concentration of alcohol gas in the air increases. Using a simple circuit can be converted to the change in conductivity of the gas concentration with the corresponding output signal. MQ-3 gas sensor with high sensitivity to alcohol, gasoline can resist, smoke, water vapor interference. This sensor can detect various concentrations of alcohol atmosphere, is a low-cost sensors for a variety of applications主な仕様 MQ-3 Alcohol, Ethanol Gas SensorbrInput 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 4VbrSpecial 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 .brSize: 32(L)x20(W)x16(H)mm/1.26"x0.79"x0.63"brPackage Include: 2PCS MQ-3 Sensor Module
