1PCS MQ-2 MQ2 Rauch Gas LPG Butan Wasserstoff Gas Sensor Detektor Modul Für Arduino
Smart Electronics 1pcs MQ2 MQ 2 MQ-2 Smoke Liquefied Flammable Methane Gas Sensor Module for Arduino Diy Starter Kit
Gas may be used in homes and factories leakage monitoring device suitable for the detection of gas, butane , propane , methane , smoke , etc.
Using 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 stability
Rapid response and recovery characteristic
Input 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 negative
DO: TTL switching signal output
AO: analog signal output
