Not only temperature affects systems performance but also humidity can cause rapid deterioration of systems. Monitoring humidity in a data center is as important as monitoring temperature! Too low humidity may result in ESD causing immediate permant equipment damage. Too high humidity could create corrosion on components, a slow and often irrevirsible process. 

ServersCheck offers a low cost PoE & SNMP ethernet based sensor for monitoring not only humidity but also temperature 24x7. This sensor measures the relative humidity (0 and 100 % RH) and temperature (-40 C and +75 C, -40 F to +167 F) with improved resolution. This sensor is designed to monitor conditions in server rooms and other sensitive area's. 

All ServersCheck sensors connected through the SensorGateway are SNMP enabled. This means that one can query any sensor using any Network Management System such as Tivoli, OpenView, Nagios, MRTG, ... 

The sensor can alert you autonomously through email or SNMP Traps. Need SMS alerting? Then this is possible by using the ServersCheck Monitoring Software/Appliance which monitors centrally all different sensors running in your network.
