Getting IR signal from remote controller
According to this FCC test report for the LXZK-TX1021 remote control, this remote uses HF at 433.92MHz.
In other words: it is not an IR remote; it uses radio, so it does not send any IR you can receive.
It did pass the test, though.
Apart from that, you should put a &gt;20kΩ pull-up resistor in between 5V and Out, and a small cap in parallel with the 100μF, both as described in the datasheet, if you want to wire the receiver up correctly.
