What is an IR sensor? | FierceElectronics

2019-07-29· An infrared (IR) sensor is an electronic device that measures and detects infrared radiation in its surrounding environment. Infrared radiation was accidentally discovered by an astronomer named William Herchel in 1800. While measuring the temperature of each color of light (separated by a prism), he noticed that the temperature just beyond the red light was highest. IR is invisible to the ...

OSEPP - Arduino Compatible Products - IR Detector

Much like an IR Remote, the IR light is oscillated at a defined frequency and detected at that same frequency; this enables the sensor to work in noisy environments. You can adjust the frequency to avoid interference with other detectors or other IR sources. You can set the distance the sensor is triggered from by adjusting the Distance potentiometer. Notice the LED will light up when it is ...

How UV, IR and Imaging Detectors Work - Sensor Technology

An IR detector is a pyroelectric sensor that is capable of detecting thermal radiation and is rather sensitive to variations of the received light signal. A tantalum/lithium crystal is associated with an OP amp or a field-effect transistor. An optical filter (a spectral gate) chooses a specific spectral band or wavelength ( µm, µm, 4 to 5 µm…). The crystal perceives the random ...
