— VCC voltage should be consistent with the working voltage of the module, and power filter should be done for operation .

— The antenna has a great influence on the receiving effect of the module. It is better to connect the 1/4 wavelength antenna, which is generally 50 ohm single-core wire. The length of the Antenna is about 575px for 315M and 425px for 433M.

— Antenna position also affects the receiving effect of the module. During installation, the antenna should be as straight as possible, away from the shielding body, high voltage and — Interference source. When using, the receiving frequency and decoding mode should match the transmission.
