Ⅰ. Product Description

 

The wireless transceiver module adopts ASK modulation to reduce power consumption. When the data signal stops, the emission current drops to zero. The data signal and the input terminal of the transmitting module can be connected with resistance or directly instead of capacitive coupling, otherwise the transmitting module will not work normally. The data level should be close to the actual working voltage of the data module to obtain a higher modulation effect.

 

The wireless receiving module is widely used in wireless remote control, remote control toys, anti-theft alarm, garage doors, rolling gates, barriers, retractable doors and other door control industries, wireless 232 data communication, wireless 485/422 data communication, digital audio, digital image transmission And other fields.

Ⅲ. RF Receiver and Transmitter Working Principle

 

Three ways to use 12V rf receiver module

1. It can be used for wireless data transmission via serial port. Generally, many control instruments and devices use serial ports. And the communication of these devices must meet the requirements of the serial port. And some special places and industrial control scenes will choose the wireless receiving module when using the wireless transmission method.

 

2. Can be used for wireless multi-channel control. In general, a pair of transmitting and receiving modules can realize up to six parallel wireless controls. If the required number of channels is greater than six, multiple pairs of transmitting and receiving modules can be used to work at the same time to meet the needs of users.

 

3. It can be used to build a multi-point star topology wireless communication network. The choice of wireless transceiver module is cost-effective, small in size, easy to use, and easy to integrate. For wireless networks with low communication speed requirements and relatively close distances, this transmitter and receiver module is very practical.

Ⅴ. Some Tips about Using RF Remote Receiver Module

 

The use of the wireless transceiver module is selected according to the effect to be achieved by the actual development. There are still some tips in the process of use.

  • The transmission interval of the wireless transmitter module will be affected by the frequency and amplitude of the modulation signal, voltage, battery capacity, antenna placement direction, and the receiving and sending environment.

 

  • It is best to install the wireless transmitter module vertically on the edge of the motherboard, and separate the surrounding components by more than 5mm to avoid the influence of the scattering parameters.

  • Generally, the maximum transmission interval in an open area is about 800 meters. In the case of obstacles, the interval will be extended. Due to the refraction and reflection in the process of radio signal transmission, some dead zones and non-fluctuating areas will be formed, and different transceiver environments will be different. Transceiving interval.

  • The data level should be close to the practical task voltage of the wireless transmitting module in order to obtain a higher modulation effect.
