... in applications that require electrical insulation without the use of opto-insulators or other expensive insulation techniques.003cbr003e.
Perform RC filtering on the output and use the op amp to build a voltage follower circuit to make the output more stable and better match the impedance of the A/D channel of the microcontroller. At the same time, two output pins are taken out (direct output and voltage follower output) for easy selection.003cbr003e.

Mainly used for qualitative detection, suitable for home and environmental gas detection equipment, ozone gas detection, gas sensor test concentration....
The module has level signal output and alarm signal indicator.
The module is with analog signal output, voltage range: 0-5V.
The level signal output is effective at low level, which can drive PNP transistors and can also be connected to the IO port of the microcontroller.
The analog output voltage increases with the increase of ozone concentration, the higher the concentration, the higher the voltage.
