Product Name: Ozone gas detection sensor module

【Semiconductor heating type - qualitative detection】

[With analog and TTL level signal output]
[Analog output voltage and concentration of a linear relationship between the need to convert the analog voltage into the resistance ratio, and then logarithmic relationship to calculate the specific concentration value. To
First, the size: 35mm X40mm X28mm long * wide * high
Second, the main components: ozone gas sensor
Third, the working voltage: DC 5V
 
Four characteristics
1, the module with a level signal output, with alarm signal indicator;
2, the sensor module with analog signal output, the voltage range: 0-5V;
3, the level of the signal output is low, can drive PNP transistor, but also access the microcontroller IO port;
4, the analog output voltage increases with the increase of ozone concentration, the higher the concentration the higher the voltage;
5, the low concentration of ozone gas has a high sensitivity;
6, with long service life and reliable stability;
7, after the warm-up with a rapid response to recovery characteristics;
8, with a mounting hole, easy to install;
9, the probe can be plug design, easy to test;
10, the module with temperature compensation, adaptability and more reliable.
 
Fifth, application:
Mainly used for qualitative testing, suitable for home, environmental gas detection equipment, suitable for ozone gas detection, gas-sensitive components Test concentration range: 10 to 1000ppb, see the data description; provide sensor product brochures.
