MQ-131 MQ131 Ozone Gas Detection Sensor Module

Size:32mm X22mm X30mmLong*Width*High
Main chip: MQ131 Gas sensing probe
Working voltage : DC5V
Features:
1With signal output indicator ;
2, Dual signal output ( analog output and TTL level output ) ;
3, TTLOutput valid signal is low ; ( output low signal light, which can be accessed microcontroller IO port )
4, Analog output increases with the concentration, the higher the concentration the higher the voltage ;
