The Infrared Emitter is based on the infrared emission infrared emission control module 940, the infrared signal emitted by the transmitter tube 940nm wavelength, the signal can be acquired infrared receiver module is a few meters away and demodulation, encoding and decoding process can be achieved with the remote control function.
The Infrared Receiver is based on HL-A838 integrated infrared receiver modules, IR transmitter module can receive incoming 38KHz modulated infrared signal, and demodulated into logic level, When it receives the modulated infrared signal then output low level, otherwise output high level. IR remote control can be completed by using application of codec.
The infrared receiver module and transmitter module can complete the infrared remote control with the codec program.The transmitting angle is about 45 degrees and the receiving angle is about 90 degrees.
The transmitter module:power supply can be 5V or 3.3V.You can manually adjust the direction of the launch tube according to the actual application requirements.The infrared receiver module:power supply voltage can be 3.3V ~ 5.5V.Low-power, wide-angle and long distance reception;Output matching TTL, CMOS level.
Note: there is no modulation circuit in the transmitting module. When used on mega2560 motherboard: the program does not need to be modified. The transmitting module is connected to pin 9 of mega2560 motherboard and the receiving module is connected to pin 2 of another motherboard.
