Ⅰ Product Overview
1.1 Product Description
E95-DTU(433Cxx-485)-V2.0 is a continuous transmission type 433M wireless digital transmission module,
built-in high-performance microcontroller and wireless transceiver chip, working in 410 to 441MHz band (default
433MHz), transmitting power 20/30dBm. It works in 410-441MHz frequency band (default 433MHz), with 20/30dBm
transmit power, the main function is that when the module is in continuous transmission mode, it can perform
continuous uninterrupted transmission under different serial port baud rates, and the data output delay at the
receiving end is low, which is suitable for the need of rapid transmission of large data volume scenarios.
Wireless digital transmission radio as a communication medium, and optical fiber, microwave, open-wire, has
a certain scope of application: it provides some special conditions in the dedicated network of real-time monitoring
signals, reliable data transmission, has a low cost, easy installation and maintenance, strong ability to bypass
the shot, the network structure is flexible, the coverage range of the characteristics of the long distance,
suitable for the point of much more dispersed, geographically complex and other occasions, can be combined with
PLC, RTU, rain gauge, liquid level meter, etc., and can be used to transmit the data to and from the network.
It can be connected with PLC, RTU, rain gauge, liquid level meter and other data terminals.
