Infrared Receiver is used to receive infrared signals and can also be used for remote control and detection. There is a |R detector on the Infrared Receiver, which is used to obtain the infrared rays emitted by the infrared transmitter. There is a demodulator inside the IR detector, looking for a 38 KHz signal. InfraredReceiver can receive signals within 10 meters. If it exceeds 10 meters, the receiver may not be able to receive the signal. We often use two Groves Lnfrared Receivers and Grove Infrared Emitters to work together.
