Characterization of RGB LEDs as Emitter and Photodetector for LED-to-LED Communication [PDF]
2020 12th International Symposium on Communication Systems, Networks and Digital Signal Processing (CSNDSP), 2020 Visible Light Communication (VLC) has rapidly grown over the last decade. However, unlike RF technologies, VLC has a simplex channel since two different devices are used for transmitting and receiving. This increases the cost and complexity of the transceiver circuit when a bidirectional link is required.

LED-to-LED based VLC systems [PDF]
Proceedings of the Workshop on Internet of Lights, 2021 Visible light communication (VLC) is an emerging short-range wireless communication technology using the unlicensed light spectrum. Light Emitting Diode (LED) is used as VLC transmitter, while photodiodes or image sensors are used as receiver, depending on the applications and hardware constraints.

Experimental Characterization of RGB LED Transceiver in Low-Complexity LED-to-LED Link [PDF]
Sensors, 2020 This paper proposes a low-complexity and energy-efficient light emitting diode (LED)-to-LED communication system for Internet of Things (IoT) devices with data rates up to 200 kbps over an error-free transmission distance up to 7 cm. The system is based on off-the-shelf red-green-blue (RGB) LEDs, of which the red sub-LED is employed as photodetector in

TSEG - The Low Countries Journal of Social and Economic History, 2022 The Dutch Drankwet (hereinafter: Liquor Act) of 1881, the result of decades of temperance activism, was met with much criticism — little had come of the national legislation’s aim to reduce the consumption of alcohol. Even so, did this also mean that little changed in the sale of alcohol? This article examines how the Liquor Act was implemented locally

LED–LED portable oxygen gas sensor [PDF]
Analytical and Bioanalytical Chemistry, 2012 A portable instrument for oxygen determination, based on the quenching of phosphorescent octaethylporphyrin by gaseous O(2), has been developed using the fluorimetric paired emitter-detector diode technique (FPEDD). The instrument configuration consists of two light-emitting diodes (LEDs) facing each other, with an interchangeable support containing a ...

LED Receiver Impedance and Its Effects on LED-LED Visible Light Communications [PDF]
2018 IEEE International Conference on Communications Workshops (ICC Workshops), 2018 This paper experimentally demonstrates that the AC impedance spectrum of the LED as a photodetector heavily depends on the received optical power, which may cause the impedance mismatch between the LED and the post trans-impedance amplifier. The optical power dependent impedance of the LED is well fitted by a modified dispersive carrier transport model

The role of far-red light (FR) in photomorphogenesis and its use in greenhouse plant production
Acta Agriculturae Slovenica, 2020 Light energy is one of the most important factors regulating the growth and development of plants. In greenhouses and other controlled- environments in which the natural radiation intensities are often low, plant production relies on supplementary ...
