<DIV> We are successfully using Websensors (<A href="http://www.eesensors.com/websensor.html">http://www.eesensors.com/websensor.html</A>). These models can monitor temp, humidity and illumination, and with add-on pieces, they can monitor for the presence of water, and electrical power voltage.</DIV>
<DIV> </DIV>
<DIV> One of the nice things about these components is that they come with Nagios check plugins and instructions on how to install/setup Nagios monitoring. They provide the monitored details over IP (not SNMP), and you can see the details at any time by using a browser to access the webpage (<A href="http://<ip">http://<ip</A> address>.<BR><BR></DIV>
