How does the 433mhz transmitter and receiver antenna enhance the signal?

1. The antenna must be impedance matched.

2. Increase the transmission gain, but the higher the gain, the narrower the lobe.

3. Increase transmission power.

The principle of antenna transmission and reception: using the antenna’s resonance principle is basically the principle of electromagnetic induction.

The high-frequency current that changes during transmission is converted into an electromagnetic field by the antenna and emitted, and the electromagnetic wave received by the antenna is converted into a high-frequency current into the machine for processing during the reception.

433 wireless module antenna installation precautions

1. Module and spring antenna connection:

Hook the hook-like part of the spring antenna to the ANT pin of the module, and weld it to complete the connection with the spring antenna.

2. Module and rubber duck antenna connection:

Solder the end of the SMA extension cord to the ANT and GND pins of the wireless module, and then connect the other end of the SMA extension cord to the rod antenna.

3. Connect the module to the suction cup magnetic antenna:

First, solder the end of the SMA extension cord to the ANT and GND pins of the wireless module, and connect it to the suction cup antenna through the other end of the SMA extension cord.

Precautions:

In order to ensure the best communication distance of the module, the antenna should not be close to the ground surface as much as possible during the use of the antenna, and the surrounding area should be kept away from obstacles;

If you use a suction cup antenna, the lead wire should be as straight as possible, and the suction cup base should be attached to a metal object.

The 433 wireless modules should use antennas with the same frequency band. The higher the antenna gain, the longer the communication distance.

The user can follow the above connection method to connect the module and the antenna. To ensure the best communication distance, please refer to the precautions.

 

How to strengthen the stability of 433MHz wireless module communication?

1. Remove obstacles.

In the city, there are obstacles such as tall buildings and metal objects, which will cause poor signal transmission. When in use, you should try to avoid obstacles, and prevent the module and antenna from high places.

2. Use matching high-gain directional antennas.

If you want the module to be in the best working condition, you must choose a matching high-gain antenna. Choosing a directional antenna with high gain can significantly increase the power density in the communication direction, thereby increasing the communication distance.

3. Proper receiving sensitivity.

Whether the module communication is reliable and whether the communication distance is far enough is related to the receiving sensitivity. Due to electromagnetic interference, industrial pollution, and the inherent noise of electronic components, appropriately increasing the receiving sensitivity can increase the communication distance.

4. Output power.

The greater the transmission power, the longer the communication distance. If conditions permit, an appropriate increase in the transmission power will help increase the communication distance.
