IR receivers (infrared receivers) are devices designed to send and receive a coded infrared signal from one device to another. The receiver outputs the unique identified code the other receiver can decode, understand and turn into the desired action. ...
The infrared signal is invisible to human eye. For a proper operation, both receivers need to physically see each other. Ideally, they should be positioned in a straight line but as the light waves, the same as all other waves can be reflected from the wall or glass.Features & BenefitsMany types of IR receivers are available on the market but generally, they can be categorised by features such as: Supply Voltage Carrier Frequency Transmission Distance Power Dissipation Package TypeTo choose the right receiver you need to consider your project requirements. For some users, the transmission distance isnt as necessary as for example the power consumption. From the wide range of IR receiver available on the market, the user is going to be able to find the one that meets all needs.
IR transceivers (infrared transceivers) are transmitters and receivers combined into a single circuit unit. Some transceivers can transmit and receive signals at the same time, while others can only do one at a time. Depending on the type of transceiver, the device may have a broad light beam, or a focused beam that requires more precise positioning in order to function properly....
Types of IR transceivers
IR transceivers can be categorised by size, speed, supply and voltage. The maximum idle current available is 10A, while the most common size for an IR transceiver is 1 metre with some being as small-scale as 875nm (nanometre) or as wide-ranging as 6.5 metres.
What are IR transceivers used for?
IR transceivers are generally used in communications devices, such as mobile phones. They can also be used for entering and collecting data in the field. A researcher using a handheld IR transceiver, for instance, can collect data on their portable device and then send it to a PC using an infrared transceiver.
