Oxygen Sensor
Oxygen Sensor work with our MDVR, show atmosphere is about 20.7%. When the oxygen concentration is below 19%,
Create alarm, safe people!
- Description
- Parameters
Equipment: Through RS232 to connect with MDVR, it can monitor school bus inside/carriage’s oxygen concentration.
The normal oxygen concentration in a normal atmosphere is about 20.7%. When the oxygen concentration is below 19%,
it will occur alarm. And linkage with IO-output alarm(with external alarm light, driver will know and open window).
Also, it can link with the specified camera on the CMSV6, pop up the screen on CMSV6 automatically.
CMS client：CMSV6 GUI will show oxygen concentration value(like below vehicle information).
