MQ-131 ozone sensor

Description : MQ131 Ozone O3 Gas Sensor Sensing Module Detection Concentration Range 10PPB-2PPM Size: 32mm X22mm X30mm The main chip: MQ131, Gas sensing probe Working voltage: DC 5V Features: * with the signal light indicates the output; *Dual signal output (analog output, and TTL-level output) *TTL output valid signal is low. (When output low signal light can be directly connected to the microcontroller IO port) *Analog output increases with the concentration, the higher concentration the higher voltage . *Ozone O3 has a high sensitivity and good selectivity； (detection concentration range 10PPB-2PPM) *Has a long life and reliable stability; *Quick response and resume; *Probe can plug design for easy testing.
