Product Summary:
The wireless transmission module W1 of Miran Sensor is a high-performance, low-power, long-distance micro-power RF wireless data transceiver radio. It has internal automatic spread spectrum calculation and leading CRC error correction processing, does not change any data and protocol of the user, and adopts a half-duplex transparent transmission mechanism to realize the function of wireless replacement. The RF chip of the wireless data transmission radio is based on spread spectrum frequency hopping technology, which surpasses the existing GFSK radio in stability, anti-interference ability and receiving sensitivity. Equipped with a low-power high-speed processor, the data processing capability and computing speed are improved. Users can flexibly configure the radio's operating frequency, serial port rate, spread spectrum factor, effective data ratio and spread spectrum bandwidth according to actual needs through the upper computer software configured by our company. The operation is simple and easy to use. The software and hardware of the wireless data transmission radio are all industrial-grade design standards with strong protection measures. It is guaranteed to work stably and reliably under special environments. The radio is designed with a variety of interfaces, including industrial-grade 485, industrial-grade TTL and standard DB9 serial port 232, and DC6~35V wide voltage input. It is a data transmission radio that is completely suitable for industrial applications.
