Details

MQ-7 sensor has high sensitivity to carbon mono oxide. It is low cost and suitable for various applications.

Using high-quality dual-panel design, with a power indicator and TTL signal output instructions; With a the DOUT switch signal (TTL) output, and AO analog signal output; TTL output valid signal is low level; (When the low level output signal lights, it can be connected directly to the microcontroller or relay module)

TTL output signal can be connected directly to a microcontroller IO port or connect to the relay module, potentiometer is used to adjust the output level transition threshold

FEATURES:

  • Wide detecting scope
  • Stable and long life
  • Fast response and High sensitivity
  • Analog and Digital Outputs
  • Trigger Level configuration Potentiometer

MODULE ASPECTS:

  • Size: 32mm X22mm X27mm
  • Operating voltage: DC 5V
  • Analog Output (AO): 0~5V analog output voltage
  • Digital Outout (DO): 0V or 5V output (the higher the voltage the higher the concentration)
  • Configuration: Through Potentiometer (adjusts the output level transition)
  • Preheat Duration: 20s

PIN LAYOUT:

  1. VCC (+5V)
  2. GND (0V)
  3. DO (Digital Out)
  4. AO (Analog Out)
