Even though the technology has been in use for decades, IR blasters are a key part of today's smart TVs and will be for years to come. Here's why.

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.

Recently, the progress of uncooled infrared (IR) sensors has been remarkable due to microelectronic systems (MEMS)-based pixel structure, in which free standing thermal isolation structures are ...

Developed as an alternative to passive infrared (PIR) sensors, STMicroelectronics has launched its ultra-low-power STHS34PF80 IR sensor for human-presence and motion detection in alarm and security ...
