Huntington Botanical Gardens - Sensor Web 3.1
Building on the successful deployments of Sensor Web 2 in 2000 and Sensor
Web 3.0 in 2001, Sensor Web 3.1 represents even more sophistication in
system design. The individual sensor pods are more environmentally robust
and consume less power than their predecessors.
The Sensor Web 3.1 system deployed at the
Huntington Botanical Gardens
covers a large area and, for the first time, the pods can be viewed
operating in public areas. Most of the pods are low to the ground and not
easy to spot without a map. Each pod measures light levels, air
temperature and humidity, with optional measurements of soil temperature
and soil moisture. For example, Pod 6, measures soil conditions in a patch of Day Lilies. By
correlating the soil conditions with the local light and temperature
conditions, it is possible to deduce the effects of rain in this specific area.
This Sensor Web system ran continuously for 2.5 years,
maintenance-free, until it was replaced by the new technology of
Sensor Web 5.0. It is the longest lived Sensor Web to date.
