MQ135 Air Quality Sensor Hazardous gas Detector

The
main chip: LM393, MQ135 gas sensing probe

Operating voltage: DC 5V

Signal output indicator instructions;

Dual signal output (analog output, and TTL level output)

TTL output valid signal is low; (output low signal light, which can be
accessed microcontroller IO port)

Analog output with increasing concentration, the higher the
concentration, the higher the voltage.

Sulfide, benzene Department of steam, smoke and other harmful gases with
high sensitivity

Has a long life and reliable stability

Rapid response recovery characteristics

gas-sensitive element test concentration range: 10 to 1000ppm
