SRM651/652 Middle Power Wireless Data Transmitter Module

SRM651/652 MiddlePower Wireless Data Transmitter Module

SRM651/652 middle power wireless data transmittermodule comes with high sensitivity of -121dBm and industry-leading transmittedpower of 500mW. This makes sure the module has a transmission distance between 3000m and 3500m at 1.2Kbps, and improved link performance.

The multi-channel wireless data transmitter module can work at 433 MHz or 470 MHz. This design, coupled with network ID, helpsimprove the module’s anti-interference capability thus improving itstransmission performance. Users can change and set the serial portconfiguration and RF parameters online or via PC software.

Each of our wireless data transmitter modules comes with a 4-byte network IDand a 2-byte network node ID which can be set via software. The antenna matcheswith the module automatically and controls both the receiving and sending ofdata.
