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. PIR sensors are commonly used in security alarms and automatic lighting applications. PIR sensors detect general movement, but do not give ...
Comparison of S.M.A.R.T. tools. This is an incomplete list of software that reads S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) data from hard drives. Also shows temperature of CPU, GPU, CPU core speed, Intel Turbo Boost status, CPU power consumption, system load and system fan speeds. Can control speed of GPU and system fans.
The Windows Hardware Lab Kit (Windows HLK) is a test automation framework provided by Microsoft to certify devices for Windows. Earlier similarly released frameworks were called Windows Hardware Certification Kit (Windows HCK) and Windows Logo Kit (WLK). It provides automated scheduling and execution of the driver tests that hardware vendors ...
Infrared spectroscopy (IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms. It can be used to characterize new materials or identify ...
The generalised chemical structure of polyisocyanurate showing the isocyanurate group. The polyols are abbreviated as R-groups.. Polyisocyanurate (/ ˌ p ɒ l ɪ ˌ aɪ s oʊ s aɪ ˈ æ nj ʊər eɪ t /), also referred to as PIR, polyol, or ISO, is a thermoset plastic [1] typically produced as a foam and used as rigid thermal insulation.
A barcode reader or barcode scanner is an optical scanner that can read printed barcodes and send the data they contain to computer. [1] Like a flatbed scanner, it consists of a light source, a lens, and a light sensor for translating optical impulses into electrical signals. Additionally, nearly all barcode readers contain decoder circuitry ...

An occupancy sensor is an indoor device used to detect the presence of a person. Applications include automatic adjustment of lights or temperature or ventilation systems in response to the quantity of people present. The sensors typically use infrared, ultrasonic, microwave, or other technology. The term encompasses devices as different as PIR ...
