IR Transmitter Infrared Remote Hat Expansion Board 38KHz Transceiver Shield for Raspberry Pi RPi B+/2B/3B

hi in this lesson we'll learn about the ir sensor the ir sensor is a little module that uses ir signal in order to receive data to it there is ir receiver and ir transmitter this sensor particularly is an ir receiver not an ir transmitter it's important to understand the difference usually we use remote as transmitter module and this module is able to receive the remote controller codes which we call it ir receiver for example if we are an air conditioner and then we have a controller for the air conditioner the air conditioner itself has an ir receiver module into it but the air conditioner remote is the ir transmitter so later on we will use a transmitter device such as remote to set the signal to the ir receiver and see if we can get it the ir receiver have three pins first one is signal then we have vcc and gnd vcc mgnd provide power to the module and signal used to read the informa
