Détecteur Monoxyde de carbone MQ-9

Détecteur Monoxyde de carbone MQ-9


  • 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
  • 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 ): 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 phenomen,because the internal heating wire,if hot is not normal .


Wiring:


  • VCC: positive power supply (5V)
  • GND: power supply is negative
  • DO: TTL switching signal output
  • AO: analog signal output
