MQ7 Carbon Monoxide Gas Sensor

HUABAN 2枚 MQ-7 MQ7一酸化炭素ガス検出アラームセンサーモジュール MQ-7 Carbon Monoxide Gas Sensor 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/1.26"x0.79"x0.76" Package Include: 2PCS MQ-7 Sensor Module 説明 MQ-7 gas sensor is sensitive material used in clean air, low conductivity tin dioxide (SnO2). Detection method using low temperature cycling (1.5V heating) detect carbon monoxide, airborne sensor conductivity increases with the increase of the concentration of carbon monoxide gas, high temperature (5.0V heating) cleaning stray gas adsorption at low temperature. Using a simple circuit can be changes in the conductivity, concentration of the gas is converted to the corresponding output signal. MQ-7 gas sensor with high sensitivity for carbon monoxide, this sensor can detect a variety of gases containing carbon monoxide, is a low-cost sensors for a variety of applications, 商品コード57070144709商品名HUABAN 2枚 MQ-7 MQ7一酸化炭素ガス検出アラームセンサーモジュール型番JP-MW-Sensor-Gas-MQ-7-2PCS
