Product Name: ozone gas detection sensor module
[semiconductor heating — — qualitative detection]
[analog and TTL level signal output]
[Analog output voltage and concentration is not linear relationship, the analog voltage needs to be converted into resistance ratio, and then the specific concentration value can be calculated through the logarithmic relationship. ]
Size: 35mm X40mm X28mm long * width * high
Two. Main components: ozone gas sensor
Three, working voltage: DC 5V
1, module with level signal output, with alarm signal indicator.
2, sensor module with analog signal output, voltage range: 0-5V;
3, level signal output low level effective, can drive PNP transistor, also can connect microcontroller IO port;
4, the analog output voltage increases with the increase of ozone concentration, the higher the concentration, the higher the voltage.
5, high sensitivity to low concentration ozone gas.
6. It has long service life and reliable stability.
7, preheating has fast response recovery characteristics.
8, with installation holes, convenient fixed installation;
9, the probe can be plugged out for easy trial.
