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.

Small digital Combi Sensor for light, movement and presence. The Motion Sensor works with HF technology and consists of 4 internal, separately adjustable sensor units. The 16-bit Light Sensor measures the visible spectrum (V-lambda) and is perfectly suited for exact daylight-dependent control.

BUS combi-sensor for light, motion, presence in a small mini design for a wide range of installation options. The PIR motion sensor is perfect for detecting presence and motion in workplaces or small to medium-sized rooms. An integrated 16-bit light sensor measures the visible spectrum (V-lambda) of light and is perfect for daylight-dependent control.

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