Description: SRWF-505, the low-power wireless transceiver data module is used as the wireless data transceiver in short-ranges, with the small size, weight and power consumption and good stability and reliability. Narrowband low power UHF wireless data transmitters and receivers with channel spacings as low as 25 kHz:
it is mainly used as following show:
*orienting the steel wheel
*Queue management system
*intellectual over-weight detecting system
*home automation system
* AMR  Automatic Meter Reading
* Wireless alarm and security systems
* 433 / 868 and 915 MHz ISM/SRD band systems
* Data radio can be used for Wireless conference voting system;
* Radio modem can be used for Sports training & competition;
* Wireless sensor Industrial wireless remote control and air conditioning remote controller;
* Observation and predication of oil well and hydrological information;
* Wireless RS232/RS485 conversion/connector;
* Point to multi-point wireless network, wireless on-the-spot bus and automatic data collection system;

Condition: Technical specification of SRWF-505:
1. Transmission power is 20dbm (100mW)
2. Transmit distance is 1500m
3. Center frequency is 433MHZ/868MHz/915MHz.
4. We use GFSK/FSK Modulation mode, Interface format: 8N1/8E1/8o1 user-defined
5. We have three Interface mode : UART TTL / RS-232 / RS-485. The details of how to connect the interface you can read the user manual.
6. Interface baud rate is 1200/2400/4800/9600/19200bps, you can only choose one of it when you buy it.
7. Offering a transparent data interface, it is suitable for any standard or non-standard user protocols;
8.Transmitting current <190mA,Receiving current <32mA,Sleeping current  <30uA
9. Even for semi duplex communication, the user doesn't need to prepare excessive programs, only receiving/transmitting the data from the interface. SRWF-505  will automatically, complete the other operations, such as transmission/receiving conversion in the air, control, etc.
10.Power supply +4.5~5.5VDC
