Detailed Product Description
Wireless transmitter module
Short range wireless data transmission
Wireless data collection
Features
1).micro-power launch, with the transmit and receive status indicator,transmit power is 20mW, Transmiting state, the light is red, Receiving state, the light is green.
2).ISM frequency band, without the need for frequency
Carrier frequency 433MHz, if there are special requirements are also available for 315/868/915MHz carrier frequency.
3). High anti-interference ability and low error rate
Based on FSK modulation, high-efficiency forward error correction channel coding technology to improve the data of anti-burst interference and random interference.
4). Excellent transmission performance In the line of sight case, the antenna position "3 meters away, the reliable transmission distance can up to 300m (BER = 10-6/1200Bit/S).
5). Transparent data transmissionTo provide transparent data interface, interface baud rate is 1200/2400/4800/9600/19200Bit/s,format is 8N1/8E1/8O1,users can set it. Air baud rate is 1200/2400/4800/9600/19200Bit/s . users can set it
6). Multichannel
Standard module provides four channels to meet customers a variety of communication combinations.
7). Three kinds of interface mode
Module provides three kinds of interface modes, according to the user's requirements,it can be defined as a standard RS-232 / TTL / RS-485 interface.
8). Large data buffer
In the data transmission times of at least one transfusion of more than 120BYTE data frame, when the air is greater than the baud rate serial port baud rate, at least more than one data frame transmission 200K.
9).Intelligent Data Control
Communicate without the need for other controls, as long as from the interface to send / receive data,Other operations such as air / receive conversion, control, the module can be done automatically.
10).Low Power
When receiving current <18mA, firing current ≤ 50mA
11).High reliability, small size, light weight,
A single chip radio frequency integrated circuit and chip MCU, a small external circuit, high reliability. Provides two kinds of packages: (1) metal casing. (2) bare board.
