Remark
1. VCC voltage: module operating voltage and good power filtering;
2. The antenna greatly influences module reception; preferably connect to a 1/4 wavelength antenna, typically 50 ohm single conductor, the length of the antenna for 433 MHz is about 17 cm;
3. Antenna position also affects module reception. During installation, position the antenna as straight as possible, away from shielding, high-pressure, and interference sources; the frequency used for receiving, decoding, and oscillation resistor should match the transmitter.
