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)
Long life and reliable stability;
Quick response and resume;
Probe can plug design for easy testing.
Package includes:
1 X MQ-131 Ozone Gas Detection Module O3 Concentration Gas Sensor Module
