What is an Infrared Sensor? (with pictures)

An infrared sensor is an electronic device that emits and/or detects infrared radiation in order to sense some aspect of its surroundings. Infrared sensors can measure the heat of an object, as well as detect motion. Many of these types of sensors only measure infrared radiation, rather than emitting it, and thus are known as passive infrared (PIR) sensors. A USB dongle with an infrared sensor ...

Consumer IR - Wikipedia

Consumer IR, consumer infrared, or CIR is a class of devices employing the infrared portion of the electromagnetic spectrum for wireless communications. [citation needed] CIR ports are commonly found in consumer electronics devices such as television remote controls, PDAs, laptops, and functionality of CIR is as broad as the consumer electronics that carry it.

Senzor infraroșu pasiv - Wikipedia

Senzorul infraroșu pasiv (în engleză: PIR sensor) este un dispozitiv electronic care măsoară radiația infraroșie emisă de obiecte aflate în câmpul său vizual. Este mai ales folosit în construcția detectoarelor de mișcare. Detectoare de mișcare. Un detector de mișcare este un dispozitiv de recunoaștere a mișcărilor de corpuri (obiecte, persoane) în vecinătatea lui. Un ...

Infrared Sensor - How it Works, Types, Applications ...

IR sensor is a simple electronic device which emits and detects IR radiation in order to find out certain objects/obstacles in its range. Some of its features are heat and motion sensing. IR sensors use infrared radiation of wavelength between to 1000µm which falls between visible and microwave regions of electromagnetic spectrum. IR region is not visible to human eyes. Infrared spectrum ...

Gassensor – Wikipedia

Problematik chemischer Sensoren. Das Gebiet der chemischen Sensoren ist relativ jung. Während Sensoren zum Messen physikalischer Größen wie beispielsweise Temperatur, Druck und Beschleunigung wasser- und luftdicht verschlossen sind, steht ein chemischer Sensor wie der Gassensor in direkter Wechselwirkung mit seiner Umgebung. Dadurch ist er auch wesentlich …

IR (Infrared) Obstacle Detection Sensor Circuit

· An IR sensor consists of an IR LED and an IR Photodiode; together they are called as Photo – Coupler or Opto – Coupler. When the IR transmitter emits radiation, it reaches the object and some of the radiation reflects back to the IR receiver. Based on the intensity of the reception by the IR receiver, the output of the sensor …

Infrared sensors - Sensor Technology - Metropolia Confluence

Break beam sensors. These types of Active IR sensor have emitter and receiver placed in such a way that the IR emitted by the emitter falls directly in to the receiver. During the operation, IR beam is emitted continuously towards the receiver. The flow of IR can be interrupted by placing an object between the emitter and receiver. If the IR is transmitted but altered then receiver generates ...

CCD-Sensor – Wikipedia

CCD-Sensoren sind lichtempfindliche elektronische Bauelemente, die auf dem inneren Photoeffekt beruhen. „CCD“ ist hierbei die Abkürzung des englischen charge-coupled device (dt. ‚ladungsgekoppeltes Bauteil‘), das im CCD-Sensor verwendet wird.. Ursprünglich wurden 1969 CCDs für die Datenspeicherung entwickelt. Jedoch wurde schnell bemerkt, dass diese Bauelemente …

Typically the spectral range of thermal radiation is from 7 to 14 μm. [61], The first BioFET was the ion-sensitive field-effect transistor (ISFET), invented by Piet Bergveld for electrochemical and biological applications in 1970. So the resistance of the receiving tube is lower; thus, the comparator outputs low and the indicator LED lights up. 7) Power light and indicator of digital signal ...

Infraröd strålning – Wikipedia

Infraröd strålning (IR-strålning) är elektromagnetisk strålning inom våglängdsområdet 700 nm till 1 mm, det vill säga våglängder strax över de för synligt ljus.. Infraröd strålning kallas ofta värmestrålning. All värmeöverföring genom strålning sker dock inte genom infraröd strålning, så det är en missuppfattning att värmestrålning och (IR)strålning skulle vara ...
