Foursprung: New climate control sensor from Bosch monitoring air quality

Bosch has designed a robust and reliable sensor. This uses a spectroscopic method for measuring the amount of carbon dioxide in the interior compartment of a car Selectively. The Climate Control Sensor provides a demand controlled circulating-air mode of air-conditioning systems. It guarantees a supply of fresh air to the passengers and allows for a more efficient operation of the system. Carbon dioxide (CO2) is a colorless, non flammable and odorless gas which occurs in nature in very low quantities. It is an essential part of the air and plays an important role in the environment – for instance in photosynthesis. If people sit in close proximity, they will deplete the available oxygen, which increases the CO2 content in the air. This results in decreased concentration.

It is possible to identify even small concentrations below 0.02 percent by volume.
In future vehicle air conditioning systems using CO2 as a coolant, the new Bosch sensor can also be used to monitor a leakage in case of malfunction.

The robust and compact two-channel radiation detector enables a reference measurement. The sensor can be easily modified for measuring concentrations of other gases such as carbon monoxide (CO) or natural gas.

The device is not bigger than a cigarette box.
