Gas sensor MQ-131

Gas sensor MQ-131 fast response characteristics, Mounting holes to facilitate fixed installation. The probe can plug design for easy testing.
Signal light indicates the output,Dual signal output (analog output, and TTL-level output)
TTL output valid signal is low; (low output signal light, can be accessed by the microcontroller IO port)
Analog output increases with the concentration, the higher the voltage the higher the concentration.
The ozone gas with high sensitivity (detection concentration range 10PPB-2PPM Ozone). Long life and reliable stability.
