SRWF-1101, 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;

Technical specification of SRWF-1101:
1. Transmit power is 50mw.
2. Transmit distance is 150m in-building range, 700m in open ground.
3. Center frequency is 433MHZ / 315MHZ / 868MHZ.
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. You can choose only one of it when you buy it.
6. Interface baud rate is 1200/2400/4800/9600/19200bps, you can choose them as freedom.
7. Offering a transparent data interface, it is suitable for any standard or non-standard user protocols;
8.Transmitting current ≤80mA,Receiving current ≤20mA,Sleeping current ≤20uA
9.Power supply +3～5VDC
10.Even for semi duplex communication, the user doesn't need to prepare excessive programs, only receiving/transmitting the data from the interface. SRWF-1101  will automatically, complete the other operations, such as transmission/receiving conversion in the air, control, etc.
