MQ-131 (Ozone Gas Detection Sensor Module)

Description

1. With signal output indicator light; 2. Dual signal output (analog output and TTL level output); 3. TTL output effective signal is low level; (the signal light is on when the output is low level, and can be connected to the IO port of the single-chip microcomputer) 4. The analog output increases as the concentration increases, the concentration Y is high and the voltage Y is high; 5. High sensitivity to ozone gas, (detection concentration range 10PPB-2PPM) Size: 32mm X22mm X27mm length X width X height Main chip: LM393, MQ-131 gas sensor Working voltage: DC 5V It has a long service life and reliable stability of KE; Fast response and recovery characteristics; With mounting holes, convenient for fixed installation; The probe can be plugged and unplugged, which is convenient for testing. Application:Ozone gas detection devices used in homes and atmospheric environments, Material:Plastic, metal colour:Blue Package Contents: 1 x ozone sensor module Only the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
