Hot selling E95M-DTU(400SL30-485) LoRa spread spectrum AT command, serial port online upgrade, 433MHz global free frequency band

Product Descriptions

E95M-DTU (400 SLxx-xxx) is a wireless digital radio station using military grade LoRa modulation technology, with multiple transmission modes, working in (410.125MHz~493.125MHz) band (default 433.125MHz), the station provides transparent RS485 

/ RS232 / TTL interface, plastic case, rail installation structure, support 8~28V (DC) wide voltage, voltage input. LoRa spread frequency technology will bring further communication distance, and have the advantage of strong anti-interference ability. 

Wireless digital radio as a kind of communication media, and optical fiber, microwave, open line, have certain scope of application: it provides some special conditions of private network monitoring signal of real-time and reliable data transmission, with 

low cost, convenient installation and maintenance, shooting ability, flexible network structure, far coverage characteristics, suitable for point and scattered, complex geographical environment, and PLC, RTU, rainfall gauge, liquid level meter data terminal.
