Product details of MQ4 Natural Gas Sensor For Arduino
- 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
