What is the difference between RF and iR wireless ...


What is the difference between RF and iR wireless technologies? RF (radio frequency) technology uses radio waves to transmit the audio signal. These are susceptible to RF interference. IR (infrared) technology uses infrared light to carry the audio signal thus keeping the signal in the room and eliminating RF interference.

RFID vs Barcode Advantages, Disadvantages Differences


Nov 21, 2019· RFID stands for radiofrequency identification, which uses radio waves to transmit information from RFID tags to an RFID reader. A tag contains a sensor attached to an antenna that enables the transmission of data to the …

UltraWideband Positioning Sensor Technology Inpixon


Ultrawideband, or UWB, is a shortrange RF technology for wireless communication that can be leveraged to detect the location of people, devices, and assets with unrivaled precision. Like other communication protocols including Bluetooth and WiFi, UWB can be used to transmit data between devices through radio waves.

MEMSBased BatteryLess RFID Infrared Sensor Tag with ...


Jan 31, 2019· Abstract: In this paper we demonstrate for the first time, a batteryless radio frequency identification (RFID) infrared (IR) sensor tag capable of detecting and recording the presence of a specific IR signature associated with an event of interest. Unlike existing passive sensor tags that can only perform sensing and recording functions when wirelessly powered …

IR vs. RF Remote Control What''s the Difference? | Inside ...


IR stands for Infared and means the remote must be pointed directly at the receiver. RF stands for Radio Frequency and means the remote is multidirectional. Just about every remote that comes with any piece of A/V equipment these days uses an IR based control system.

Proximity Sensors vs. Industrial RFID: Know When to Upgrade


Whereas a proximity sensor detects the presence of a piece of metal, and knows that the pallet has arrived (or is it just a bolt that fell off the assembly robot and triggered the sensor?), an RFID system detects a data tag, reads its memory containing associated product information, and knows the identity of the part in the process station.

What is an IR sensor? | Fierce Electronics


Jul 29, 2019· 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 ...
