    Module Applications:

  For carbon monoxide detection device family, the environment. Suitable for the detection of carbon monoxide gas and the like.

  Module Features:

  1, using high-quality dual-panel design, with power indicator and TTL signal output instructions;

  2, with a DO switch signal (TTL) output and analog output AO;

  3, TTL output valid signal is low. (When the output low signal light can be directly connected microcontroller or relay module)

  4, analog output voltage, the higher the concentration, the higher voltage.

  5, carbon monoxide detector has a good sensitivity.

  6, there are four screw holes for easy positioning;

  7. Product dimensions: 32 (L) * 20 (W) * 22 (H)

  8, with a long life and reliable stability

  9, rapid response recovery characteristics

  Electrical performance:

  Input voltage: DC5V Power (current): 150mA

  DO output: TTL digital 0 and 1 (0.1 and 5V)

  AO output: about 0.1-0.3V (relatively clean), the highest concentration voltage 4V
