  • It adopts high quality double panel design with power indication and TTL signal output indication;
  • It has DO switch signal (TTL) output and AO analog signal output;
  • The TTL output valid signal is low. (When the output is low, the signal light is on, it can be directly connected to the MCU or relay module)
  • The voltage of the analog output, the higher the concentration, the higher the voltage.
  • It has good sensitivity to gas and natural gas detection.
  • there are four screw holes for easy positioning;
  • product dimensions: 32 (L) * 20 (W) * 22 (H)
  • has a long service life and reliable stability
  • fast response recovery characteristics
