Spinwave Systems, Inc.

Wireless Zone Temperature Sensor, SWS-T
Type:  Sensor
Description:  Spinwave's wireless temperature sensors can be easily interfaced to any building automation system, by either: Mapping sensor's temperature and/or set point to analog outputs and override button status to digital outputs on Spinwave's DDC I/O interface (SWRF-IO), or Mapping sensor data to pre-configured Modbus registers or other industry protocol objects on Spinwave's wireless protocol gateways. The wireless sensor network (based on IEEE 802.15.4) outsmarts changing RF interferences with self-adapting frequency agility (patent pending). Sophisticated power management results in long battery life; 3 to 8 years, depending on transmission intervals. Battery health is continuously monitored.
Connectivity:  Modbus, Modbus TCP
Features:  Sensors can be battery-operated or line-powered; sensor parameters can be easily changed wirelessly; wide range of mounting options; long battery life; interfaces to virtually any automation system
Specifications:  Radio Characteristics: 2.4GHz, IEEE 802.15.4, Receiver Sensitivity -95dBm, Receiver Adjacent Channel Rejection +/-5MHz, 46/39 dB, Receiver Alternate Channel Rejection +/-10MHz, 58/55 dB; Open field Range: Receiver/Router: up to 3500 ft. (1 km), Receiver/Sensor: up to 700 ft. (230 m) In-building Range per hop (Sensor to Repeater or Repeater to Repeater) 120 ft. (40 m) in typical commercial office building; transmission interval: 21 seconds, user configurable; Power: 2 AA Lithium batteries, optional power supply: 110VAC/5VDC
