How Do Motion Sensors Work? As their name indicates, motion detectors are special types of sensors that alert you if they detect any movement in the spaces they’re set to monitor. There are actually ...

Radar sensors, for instance, can be designed as simple Doppler-based motion detectors, using a straightforward algorithm to determine if an object is approaching or moving away from the sensor.

Enters STHS34PF80, an infrared (IR) sensor that contains thermal transistors to detect stationary objects. Moreover, unlike PIR sensors needing a Fresnel lens to sense moving objects, this motion ...

Designed specifically to address the limitations of existing passive infrared (PIR) sensors that miss the mark when detecting stationary objects, the STHS34PF80 is an economical, ultra-low power ...

STMicro STHS34PF80 is a new IR sensor designed for IoT and Smart Home devices requiring motion and/or presence detection that offers an alternative to traditional passive infrared (PIR) sensors and is ...

Passive InfraRed sensors (PIRs) are electronic devices which are used in some security alarm systems to detect motion of an infrared emitting source, usually a human body.

Passive Infrared (PIR) sensors are commonly used in indoor applications to detect human presence. PIR sensors detect human presence by detecting the change in infrared radiation across the polarity of ...
