Review on Acxico Transceiver Infrared Transmitter Receiver by Tricia Grundmeier
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 $20 for a good product, not $6 for a useless paperweight.
- 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.
- Safety
