Our eibabo catalogs of motion sensors offers a wide range of motion detectors and sensors for surface mounting and flush mounting. In addition to motion detector sensors, we also provide add-on automatic switches and automatic switches, surface switches, motion detectors, ceiling detectors and ceiling presence detectors, BLC and IR switches, Busch-detectors, wireless motion-brightness sensors, wireless detectors and wireless alarm panels, IR motion detectors, presence sensor modules and sensor modules with switches and detector sensors. Motion detector sensors are electronic sensors that detect movements in the immediate vicinity and can be used as electric switch. Thus, you can use motion detectors to turn on your lights or to trigger an alarm system. To detect movement, motion detector sensors either work actively with electromagnetic waves (high frequency or Doppler radar) or ultrasound (ultrasonic motion detector) or they operate passively by means of the infrared radiation of the environment. Some motion sensors are also available as a combination of active and passive design. Power consumption of most commercially available motion sensors is typically less than 1 W. Note that there is a reactive power of the capacitor power supply. Infrared motion detector sensors are the most common types of motion detectors. These sensors respond to changes in the ambient temperature, for example, people who pass close to the sensor. Motion detectors that work with Doppler radar or high frequency sensors respond well if the distance of moving objects to the sensor changes.
