As a communication medium, wireless data transmission radio has a certain scope of application like optical fiber, microwave and open wire: it provides real-time and reliable data transmission of monitoring signals in the private network under certain special conditions, and has the characteristics of low cost, convenient installation and maintenance, strong diffraction ability, flexible networking structure and long coverage, suitable for many points and scattered, complex geographical environment and other occasions, and can be connected with PLC, RTU, rain gauge, liquid level gauge and other data terminals.
E95-DTU(433Cxx-485)-V2.0 is a continuous transmission 433M wireless data transmission module data transmission radio with built-in high-performance single-chip microcomputer and wireless transceiver chip. It works in the frequency band of 410~441MHz (default 433MHz), and the transmit power is 20/30dBm. It has the characteristics of high-speed continuous transmission, relay networking, ultra-low power consumption, multi-level adjustable transmission power, online firmware upgrade, and long-distance communication.
High-speed continuous transmission
In continuous transmission mode, the module can perform continuous uninterrupted transmission at different serial port baud rates, and the data output delay at the receiving end is low, which is suitable for scenarios that require rapid transmission of large amounts of data. Ultra-low power consumption, 12V power supply waiting current is only 16mA.
Automatic relay networking
In general mode, automatic relay networking is supported, and multi-level relay is suitable for ultra-long-distance communication, and multiple networks run in the same area at the same time.
17 levels of rate adjustable
It supports the data transmission rate of 0.5k~470kbps, and the transmission power is multi-level adjustable to meet the needs of more applications. With powerful software functions, all parameters can be programmed: such as power, frequency, air rate, address ID, etc.
The communication distance is long
E95-DTU(433C30-485)-V2.0 has built-in PA+LNA+SAW, and the communication distance can reach 10km under ideal conditions, and E95-DTU(433C20-485)-V2.0 has built-in LNA+SAW, and the communication distance can reach 6km under ideal conditions.
The parameters are saved when the power is off
It is equipped with multiple protection functions such as power reverse connection protection, over-connection protection, antenna surge protection, etc., which greatly increases the reliability of the radio. With a built-in watchdog and precise time layout, the radio will automatically restart in the event of an abnormality and continue to work according to the previous parameter settings.
RSSI signal strength indication
Supports RSSI signal strength indication function for signal quality evaluation, communication network improvement, and ranging.
The communication key can be set by the user and cannot be read, which greatly improves the confidentiality of user data.
Upgrade the firmware online
Through the upgrade firmware provided by Yibaite, users can use the host computer to upgrade or replace the current firmware.
Multiple application scenarios
The equipment can be widely used in smart wearables, home automation, home security, personal health care, accessories and remote controls, automobiles, lighting, industrial Internet, intelligent data collection, intelligent control and other fields.
