2019 Hot Sale High Quality As62-dtu30 8km 433mhz Rf Wireless M-bus 868mhz 433 500mw Lora Module
Products Description
AS62-DTU30 is a 433MHz,1W industrial-grade wireless data transmission unit with high stability. The DTU uses SX1278 main chip, LORA spread spectrum transmission, RS232/485 level output. The DTU adopts the efficient cyclic interleaving error correction coding algorithm, which has high coding efficiency and good error correction ability. In the case of sudden interference, the DTU can correct the interrupted data packets, and the maximum continuous error correction is 64bit, which greatly improves the DTU"s Anti-jamming ability and transmission distance, and in the absence of error correction algorithm, this error packet can only be discarded. Using LORA spread spectrum technology makes the module have a longer communication distance.
