Humidity Sensors are suited for building controls.

Press Release Summary:

Relative humidity sensors are available as room relative humidity sensor and combination temperature/relative humidity sensor for those applications requiring local indication of temperature and humidity in single device. Temperature-compensated and factory-calibrated units utilize A3 technology, which eliminates problem of interference from other RF sources. Powered by two 1.5 V lithium AA batteries, they are accurate to ±2% RH.

Original Press Release:

Spinwave Systems Expands its Line of Wireless Devices with the Release of Humidity Sensors

Versions Available for Measuring Room Relative Humidity and Combination Temperature/Relative Humidity

Westford, MA - May 15, 2007 - Spinwave Systems, a leading provider of wireless sensing products for the commercial building controls and industrial automation markets, announces the availability of its new line of wireless relative humidity sensors. Spinwave's relative humidity sensors are an important addition to the company's product line as they expand the ability of Spinwave's wireless sensor networks to measure different environmental variables.

The new sensors utilize Spinwave's A3 technology, a patent pending method and system which eliminates the problem of interference from other RF sources while minimizing power consumption. The result is a highly reliable, easy to use and easy to maintain wireless sensor network.

The sensors, which are temperature compensated and factory calibrated, are available in two models - a room relative humidity sensor and a combination temperature/relative humidity sensor for those applications requiring local indication of temperature and humidity in a single device.

The units are accurate to ± 2% RH and are powered by two 1.5V Lithium AA batteries (a line powered option is available.) Estimated battery life is 3 to 8 years, depending on the selected transmission interval rate.

Sensors Easily Interface to Any Building Automation System

Spinwave's wireless relative humidity sensors can be easily interfaced to any building automation system by simply mapping a sensor's values to analog outputs on Spinwave's Direct I/O Interface board or, alternatively, mapping sensor data to preconfigured protocol objects (e.g. BACnet objects, LON SNVTs or Modbus registers) on Spinwave's BMS Protocol gateways.

Spinwave Wireless Solutions Meets the Needs of the Building Controls Market

Spinwave's wireless solutions are specifically designed with building owners, operators, and systems integrators in mind. The network is easy to install and use, requires little maintenance and provides solutions that are cost effective and ultra-reliable.
