The 38kHz Digital Infrared Transmitter Receiver Sensor Module With Remote Control for Arduino is commonly used to control electronic devices wirelessly mainly through the remote.
The infrared Transmitter Module emits infrared light, meaning that it emits light in the range of Infrared frequency. We cannot see Infrared light through our eyes, they are invisible to human eyes. The wavelength of Infrared (700nm – 1mm) is just beyond the normal visible light. Everything which produce heat, emits infrared like our human body. Infrared have the same properties as visible light, like it can be focused, reflected and polarised like visible light. Other than emitting invisible infrared light, infrared Transmitter looks like a normal LED and also operates like a normal LED
Infrared Receiver Module can receive a standard 38KHz modulation remote control signal. You can decode the remote control signal through Arduino programming. You can design a variety of remote control robots and interactive works.
The mini slim infrared remote control with 21 function keys. Its transmit distances up to 8 meters. Ideal for handling a variety of equipment indoors.
