[Introduction]：E90-DTU (400SL47) is a truly high-quality industrial-grade wireless data transmission radio.The shell adopts three-proof coating, which is Anti-Fungal, Anti-Humidity, and Anti-Salt Spray. The DTU uses LORA spread spectrum technology, and its strong anti-interference ability allows wireless communications to be used in industrial sites. More stable and reliable. The radio has a data encryption function. The data transmitted by the radio in the air is random. Through strict encryption and decryption algorithms, data interception is meaningless. It supports packet length setting and supports different real-time properties and data packets.
