Wireless modules for sending and receiving bring the possibility of centralized control for various household appliances, due to the comprehensive wiring method used in home design for the connection of many appliances. Six parallel channels are used in common.
The receiving module is directly connected to the decoder, and then the decoder is connected to the microcontroller. Through data processing and control of electronic components such as relays, the switch of each light is controlled, ultimately achieving the requirements of six-way asynchronous control, and achieving good control effect. Do you know how to use wireless modules for sending and receiving?
And it must be a multi-point star topology structure, as some extraordinary places require wireless communication.
On the one hand, this kind of transmitter and receiver module is inexpensive, and the cost of forming a star topology structure is relatively low; on the other hand, this kind of transmitter and receiver module can adopt modular design, with small size, convenient use, and easy integration.
For wireless networks with less demanding communication speeds and relatively short distances, this kind of transmitter and receiver module is very practical.
For example, for complex remote-controlled robots, certain places require multi-channel (parallel) control.
One method is to directly connect the receiving module to the decoder, and then connect it to electronic components such as relays to drive the subsequent controlled objects; another method is to connect the receiving module to the microcontroller, process the data, and then use the microcontroller to connect to electronic components such as relays to drive the subsequent controlled objects.
Usually, a pair of wireless modules for transmitting and receiving can achieve up to six parallel wireless controls. If the required channel number exceeds six, multiple pairs of transmitter and receiver modules can be used to work at the same time to meet practical needs.
Usually, many control instruments and devices use serial ports, and communication with these devices must meet serial port requirements. In some extraordinary places, such as industrial control sites, when wireless transmission is required, the transmitter and receiver modules mentioned in this article can be naturally selected.
But it must be noted that to adopt this communication method, corresponding software implementation files for format conversion must be prepared separately on the transmitter and receiver sides to achieve wireless communication. If the communication system is full-duplex, two pairs of transmitter and receiver modules can also be used to work at the same time to achieve it.
The wireless modules for sending and receiving currently available on the market have been packaged and designed, and can be directly connected to the microcontroller through the asynchronous serial port. The wireless working mode is controlled by the internal microcontroller of the module. The connection between the user's microcontroller and the module generally only has power supply and several wires for receiving and transmitting, which is very convenient to use.
