The BUS Light Control Sensor is used for the exact control of artificial light and daylight. The measured light spectrum corresponds to the lux value V-Lambda curve V(λ). It is available with and without integrated motion sensor and can also control according to presence. It is mounted on the ceiling as standard, the sensor measures the reflection of the surface below.

The calibratable Light Sensor for the ISYGLT system can be used as an outdoor Light Sensor, twilight switch or as a lux meter for monitoring and controlling indoors.

The calibratable Light Colour/Brightness Sensor for the ISYGLT system can be used as an outdoor or indoor light sensor. Many different curves and value queries are available to use the sensor for a wide range of applications. A special application is the regulation of light exactly to the desired light colour, e.g. in offices, schools, industry (e.g. control room) or museums. Due to the direct measurement, daylight is also included. Another interesting application for biologically effective lighting control is the measurement of outside light and the transfer of the exact value to the indoor.

The Daylight Sensor ZTLS-04 uses 4 light sensors to determine the light values of the points of the compass.

The digital Light Sensor with high-frequency Motion Sensor is especially suitable for indoor applications. The Motion Sensor consists of 4 internal, separately adjustable sensor units.

The digital Light Sensor with PIR Motion Sensor is suitable for implementing daylight controls, regulations and switching thresholds indoors.
