WSN-03 RS232 RS485 TTL Wireless Data Communication Module
WSN-03 wireless data transmission module is a wireless micro-power transparent data transceiver module with high stability, high cost performance and low power consumption. Compared with the general module, the module has the characteristics of small size, high sensitivity, long transmission distance, high communication rate, internal automatic completion of communication protocol conversion and data transceiver control. The module uses multi-band and multi-channel to reduce interference in transmission process in order to improve transmission performance. The module adopts interleaved whitening algorithm, forward error correction and cyclic redundancy check method, which greatly improves anti-interference and sensitivity. Users can set parameters such as serial rate, working channel, transmission power and wireless communication rate via PC serial port
Working frequency: 433/470/868/915 MHz, standard 470 MHz, batch can be adjusted for other bands.
GFSK modulation mode, half duplex communication, air receive / send conversion, connection and control automatic completion.
Receiving sensitivity up to -120dBm, transmission distance of 3500-4000 meters.
Receiving current <30 mA Normancy current <5uA.
Communication protocol conversion and RF transceiver automatic switching complete, simple and convenient to use.
Serial port 1200/2400/4800/9600/19200/38400/57600/115200, which can be configured by software.
