Description

This is a complete wireless transmitting and receiving kit, which can be applied to simple data wireless transmission, wireless remote control, anti-theft alarm system, etc. The kit has a simple structure and flexible application, and can be directly applied to the design and experimental development of various products.

The popular link is like this: MCU -> Encoder -> Transmitter ------ Receiver -> Decoder -> MCU.You can use this kit to build a system with other main control equipment, such as Arduino,Seeeduino XIAO, to implement applications such as wireless security alarms, remote control tools, and so on.

The following is the introduction of the transmitter and receiver respectively.

[Transmitter]

In the wireless transceiver kit, the wireless transmitter module model is APF03, and its working voltage range is 3-12v.It adopts OOK modulation mode, which has the advantages of fast modulation rate and long transmission rate.

OOK (on-off keying) is binary switching keying. The modulation principle is to control the passage of the carrier by controlling the opening and closing of the switching device through the binary sequence, so as to load the binary signal onto the carrier. It is a low-cost and most easily implemented modulation method, which is widely used in various occasions.

[Receiver ]

In addition, the model of the decoding wireless receiving module is RXB28, and the working frequency is 315MHz or 433.92MHz. The recommended power supply input is 5V. At this time, when the operating frequency is 315MHz, the current can be as low as 4.2mA, and the power consumption is very low.

The receiving structure of this module is a superheterodyne method, receiving OOK

wireless signal. After receiving the signal, it will directly output the COMS signal to the external IC for decoding. It has good local oscillator radiation suppression capability and can work with multiple receiving modules.
