Air conditioners

Highest comfort with maximum energy efficiency

Ensuring optimal function and energy efficiency

Using temperature and humidity sensors in air conditioning systems precisely controls different modes of operation, such as humidifying and dehumidifying. In doing so, the sensors ensure optimal functioning and improved energy efficiency.

Demand-driven control of air exchange

Sensor-based monitoring of air quality enables demand-based control of fresh air supply in air conditioning systems. This ensures optimum indoor air quality.

Air quality monitoring using PM2.5 and HCHO sensors

Pollutants such as particulate matter or formaldehyde have a significant impact on air quality and can have negative effects on health and well-being. With the help of environmental sensors, indoor pollutants can be visualized.

Reliable filter monitoring

Differential pressure sensors can be used to precisely monitor the condition of the filter in an air conditioning system. This prevents premature failure of the system and ensures optimum energy efficiency and cooling performance.

Market leader in air conditioning

Millions of air conditioners worldwide are equipped with Sensirion's sensor solutions every year.

Miniaturized CO₂ sensor

Based on a photoacoustic measurement principle, the CO₂ sensor technology could be miniaturized. The new compact design of the sensor allows easy and flexible integration into air conditioning systems.

The future of improving indoor air quality

When we think of air quality, we tend to think of air pollution in the regions surrounding our homes. We rely on measures such as the Air Quality Index to let us know when airborne pollutants in our towns or cities reach levels that may cause or exacerbate health issues.
