Infrared sensor ? IR sensor | Sensor division knowledge

IR sensors are now widely used in motion detectors, which are used in building services to switch on lamps or in alarm systems to detect unwelcome guests. In a defined angle range, the sensor elements detect the heat radiation (infrared radiation) that changes over time and space due to the movement of people. Such infrared sensors only have to meet relatively low requirements and are low-cost ...

IR (Infrared) Obstacle Detection Sensor Circuit

· An IR sensor consists of an IR LED and an IR Photodiode; together they are called as Photo – Coupler or Opto – Coupler. When the IR transmitter emits radiation, it reaches the object and some of the radiation reflects back to the IR receiver. Based on the intensity of the reception by the IR receiver, the output of the sensor is defined.

Understanding Active & Passive Infrared Sensors (PIR) and ...

· These two sensors sit beside each other, and when the signal differential between the two sensors changes (if a person enters the room, for example), the sensor will engage. That may mean it triggers an alarm, notifies authorities, or maybe turns on a floodlight. IR radiation focuses on each of the two pyroelectric sensors using a series of lenses constructed as the sensor’s housing. These ...

Was ist ein PIR-Bewegungsmelder (Passive Infrared ...

· PIR steht für "passive Infrared" oder auch "Pyroelektrischer Sensor". Ein PIR Sensor kann Temperaturänderungen von bewegten, warmen Objekten in seiner Umgebung wahrnehmen. Diese Temperaturänderung führt zu einer messbaren Änderung der elektrischen Spannung. Der Vorteil eines solchen Sensors ist also der, dass die Fehleralarmquote geringer ist.
