Description of Acxico Transceiver Infrared Transmitter Receiver

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.

WRONG PICTURES. You don't get what you thought you bought.

The transmitter is specifically marked as having an NE555 timer chip on board. The pictures show a black chip with the correct capacitors and resistors on it. I received my item, it's just a fancy LED on a blue circuit board. This is a good LED but there are hundreds of ads on Revain for the same. I bought this whole set just for a finished 38kHz signal generator. One thing is clearly visible in the photos. I received a completely different circuit board than the transmitter shown. I would pay…

Pros
  • The infrared transmitter is based on the 940 infrared control module, the infrared signal is emitted by the transmitter tube with a wavelength of 940nm, the signal can be received by the infrared receiver module at a distance of several meters, and the process of demodulation, coding and decoding can be achieved. with remote control function.
Cons
  • Safety
