Infrared transmitter module
This is their specific physical map
This time we want to introduce infrared transmitter and receiver modules, in fact, they are now in our daily life. They play an important role in lots of household appliances and are used in devices such as air conditioning, TV, DVD, etc., It is based on wireless sensing, but also can be a remote control, very easy to use.
Products
Infrared emitter converts electrical energy into near-infrared light. It is also known as infrared emitting diode. Its structure is similar with a general light emitting diode, but made of a different semiconductor material.
The infrared receiver is set to receive, amplify, and demodulate the near-infrared light into a digital signal.
The principle of infrared communication Let's look at the structure of the infrared receiver: there are two important elements insaide an infrared receiver, named the IC and PD. IC is the receiver processing element, mainly composed of silicon crystals and circuits, is a highly integrated device, its main function is to filter, shape, decode. Photodiode PD's main function is to receive the optical signal Number.
The following is a brief schematic work The modulated infrared emitting diode emittes a signal, infrared receiver, after receiving decodes, filteres, and a series of operations.
