ACEIRMC 5pcs MQ-6 LPG Gas Sensor Module Liquefied Propane Iso-Butane Butane Combustible Gas Detection Sensor for Arduino Raspberry Pi ESP8266 MQ2 5V DC (MQ-6)
ACEIRMC 5pcs MQ-6 LPG Gas Sensor Module Liquefied Propane Iso-Butane Butane Combustible Gas Detection Sensor for Arduino Raspberry Pi ESP8266 MQ2 5V DC (MQ-6)
Detectionsing high-quality dual-panel design, with power indicator and TTL signal output instructions;The switching signal having a DO (TTL) output and analog output AO ;TTL output valid signal is low . ( Low-level signal when the output light can be directly connected to the microcontroller or relay module )Analog output voltage with the higher concentration of higher voltage.A gas, natural gas, city gas , smoke better sensitivity.There are four screw holes for easy positioning ;Has a long life and reliable stabilityRapid response and recovery characteristicInput voltage : DC5V Power consumption ( current ): 150mADO 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 4VSpecial 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 .VCC: positive power supply (5V)GND: power supply is negativeDO: TTL switching signal outputAO: analog signal outputPackage included:5 x MQ-6 LPG Gas Sensor Module Liquefied Propane Iso-Butane Butane Combustible Gas Detection Sensor
