Gas Sensors
AST gas sensors often combine several measuring principles in one sensor. For concentration/quality measurement, thermal and temperature conductivity is often measured, but optical systems are also used to determine gases.
Examples for the application of our gas sensors are leakage and concentration measurement in hydrogen-powered vehicles or the monitoring of stationary fuel cell systems for energy supply. AST sensors are also required in the field of chemical energy storage (Power2Gas).
We are also involved in determining air quality, for example to control ventilation systems (HVAC). In general, our sensors can determine the properties of a variety of different gases.
All AST sensors have a µ-controller and are therefore able to calculate complex algorithms directly on the sensor. An output signal prepared in this way is made available in analog or digital form.

Air Quality Sensor
Air quality sensors constantly monitor the intensity, degree of pollution, and number of odor molecules in the exhaust air. This information can be used as a basis for adjusting fan performance to produce a pleasantly fresh ambient climate.
By continuously measuring air pollution, our sensors intelligently predict when, for example, filters need to be replaced or the next service is due.
