Visitor Counting in Recycling Centers with Universal Retro-Reflex Sensors
At recycling centers, the daily number of visitors must be recorded in order to optimally plan the staff capacities at the centers. For this purpose, two universal retro-reflex sensors with laser light are installed at the entrance and exit gates. Depending on the signal sequence, both the number and the direction of travel can be detected. Thanks to their long range of up to 20 meters and their insensitivity to interference such as rain, snow, ambient light or dust, the light barriers are ideal for outdoor use.
Universal Retro-Reflex Sensors
Universal retro-reflex sensors are suitable for the detection of glossy, chrome-plated or reflective surfaces thanks to the polarization filter. They work with red light or laser light. Objects are detected by interrupting the light beam between the sensor and the reflector.
