Visible light communication receiving circuit diagram
Source: InternetPublisher:containsmachine Keywords: Optical communication wireless communication receiving circuit diagram Updated: 2021/05/27
A simple visible light communication receiving circuit diagram. This circuit can provide a maximum output of 500mW to a 15Ω speaker when the photocell is illuminated by light from a sound-modulated LED from an appropriate infrared light transmitter (transmission distance is 137.2m). This system is suitable for situations where it is inconvenient to set up wires and lines, and is used under the condition that the wavelength is about 0.9μm. The main circuit is shown in the figure below.
