Remark

The VCC voltage should be consistent with the working voltage of the module, and the power supply is filter;
The antenna has a great impact on the receiving effect of the module. It is best to connect the 1/4 wavelength antenna. Generally, the 50 ohm single -core wire is used. The length of the antenna is about 23cm with a length of 315m.

The antenna location also affects the module receiving effect. During installation, the antenna is straightened as possible, away from the shielding body, high pressure, and interference sources; the receiving frequency, decoding method and oscillation resistance should match when using.
