Sensor Design

The infrared reflectance sensor is a small rectangular device that contains a phototransistor (sensitive to infrared light) and an infrared emitter. The amount of light reflected from the emitter into the phototransistor yields a measurement of a surface's …

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

Sep 11, 2018· Passive infrared (PIR) sensors use a pair of pyroelectric sensors to detect heat energy in the surrounding environment. 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 ...

Motion Sensor Light Switch using CD4017 & IR sensor with ...

Dec 24, 2020· How the Motion Sensor Circuit works. The IR emitter LED continuously emits infrared. When any object comes within the range, some amount of infrared reflects from the object surface and that reflected infrared can be detected by the IR receiver LED. The LM358 compares the voltage across the IR receiver LED with the predefined value.
