      • 315 – 400 nm (UV-A zone),
      • 280 – 315 nm (UV-B zone),

      • 200 – 280 nm (UV-C zone),

      illumination  or  brightness  in the visible region of the spectrum.

      Execution of work under sanitary and technical supervision in residential and industrial premises, certification of workplaces and other areas of activity.

      Structurally, the sensor is made in the form of a single unit with a cable for power connection and data exchange.

      The principle of operation of the sensor consists in converting optical radiation into an electrical signal by a photodetector with subsequent transmission of the measurement result via a wired interface in the form of a digital code.

      A 2.4 mm wide groove is made in the sensor body along the diameter for attaching the sensor to a tripod mount (optional) or to the equipment available to the consumer.

      For operation, the sensor can be connected to the Information Processing Unit (YUSUK.10.0002 PU “TKA-UFD”, supplied separately) or to any device with appropriate characteristics.

      Data exchange is carried out using the UART protocol. Connection parameters:

      • Baud rate 115200;
      • Data bits 8;
      • Stop bits 1;
      • Parity – none.

      Position of the photometric plane depending on the spectral range of the sensor

      Irradiance sensor Place the
      sensor with the photometric plane at the measuring point towards the object being measured. The photometric plane depends on the spectral range of the irradiance sensor. Make sure that no shadow from the operator taking measurements, as well as the shadow from temporarily located foreign objects, falls on the input diaphragm. The angular dimension of the measured radiation source, visible from the measuring point, should not exceed ± 10 °.

      Light sensor.
      The photometric plane is the outer face of the diffuser, while it coincides with the outer face of the sensor body. The housing design provides an angular cosine response. To take measurements, place the sensor with the photometric plane at the measuring point. Make sure the
      illumination is uniform across the sensor entrance window.

      Brightness sensor.
      This type of sensor is designed to measure the brightness of extended self-luminous objects by the overhead method. To measure, place the sensor close to the object to be
      measured without gaps. In this case, the brightness of the object in the field of view of the device should be uniform.
