New Light Sensor Bracket from Onset Simplifies Climate Change Studies, Agricultural Research.
BOURNE Bourne, town (1990 pop. 16,064), Barnstable co., SE Mass., crossed by Cape Cod Canal; settled 1627, inc. 1884. Bourne Bridge (1935), across the canal, made the town an entry point to Cape Cod and a resort and commercial center. , Mass. -- Onset (http://www.onsetcomp.com), the world's leading supplier of data loggers, today introduced a new bracket that makes it fast and convenient to mount the company's light sensors in order to calculate Normalized Difference Vegetation Index The Normalized Difference Vegetation Index (NDVI) is a simple numerical indicator that can be used to analyze remote sensing measurements, typically but not necessarily from a space platform, and assess whether the target being observed contains live green vegetation or not. (NDVI NDVI Normalized Difference Vegetation Index ) values. NDVI is the standard measure of the density of green vegetation in an area.
Ideal for a range of monitoring applications - from climate change studies to agricultural research - the NDVI Light Sensor Bracket ensures accurate sensor positioning to provide ground-truth verification of satellite NDVI measurements, and ground-based data when satellites are not available. It also provides NDVI values at a finer resolution than is possible with satellite NDVI, which is useful for monitoring vegetation in test plots or sites.
The NDVI Light Sensor Bracket can be configured with Onset's line of research-grade weather stations, including the company's web-based HOBO([R]) U30 Remote Monitoring (protocol) remote monitoring - (RMON) A network management protocol that allows network information to be gathered at a single computer. Whereas SNMP gathers network data from a single type of Management Information Base (MIB), RMON 1 defines nine additional MIBs that provide a Systems, 4-channel HOBO Micro Stations, and 15-channel HOBO Weather Stations. The systems offer plug-and-play operation, and can be equipped with a range of sensors for measuring air temperature, relative humidity relative humidity

The NDVI Light Sensor Bracket is priced at $18 and will be available from Onset on July 15, 2009.
Onset Computer Corporation has been producing small, inexpensive, battery-powered HOBO data loggers since 1981, and has sold over 1,000,000 loggers that are used throughout the world by over 50,000 customers. The company manufactures a broad range of data logger and weather station products that are used to measure temperature, humidity, light intensity, voltage, and a broad range of other parameters. Onset data loggers are used in a wide range of research, commercial, industrial, and renewable energy applications.
