9pcs Gas Detection Sensor Module MQ-2 MQ-3 MQ-4 MQ-5 MQ-6 MQ-7 MQ-8 MQ-9 MQ-135 Sensor Module Gas Sensor Starter Kit
NOTA:- POSIBILIDAD DE ENVIO CON ASM URGENTE (ASM SOLO PARA ESPAÑA).
- ASM TRANSPORTE NO ENVIO A BALEARES, CANARIAS, CEUTA Y MELILLA!
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 characteristics
- 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 .
- VCC: positive power supply (5V)
- GND: power supply is negative
- DO: TTL switching signal output
- AO: analog signal output
