Unlike infrared optical sensors that use an LED transmitter and IR receiver, the PIR emits nothing. As its “passive” name suggests, it responds only to infrared energy radiated by the object being ...

Geneva, Switzerland, July 24, 2023 – STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, is launching a novel ...

Researchers have developed a highly sensitive method for detecting hotspots in the environment, such as bushfires or military ...

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. All objects, living or not, ...

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 ...
