Why is humidity monitoring important?


 i What is a sensor?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

Hardware needs special protection

Hardware needs special protection

Even in today’s Cloud age, most firms still need an IT infrastructure which includes on-site hardware. And this hardware requires special protection. When setting up such protection, companies must not only worry about unauthorized access to their server room but also environmental factors such as temperature and humidity.

With its tendency to steam up hardware, corrode expensive equipment, and cause electrical malfunctions, humidity can be a nightmare for any system administrator. If humidity levels in your server room are too low or too high, then you may be putting important software and applications, business-related processes, valuable data, and the work of entire departments at risk. The best way to ensure everything stays safe and sound is to implement 24/7 monitoring.

Hygrometer sensors

Hygrometer sensors

With PRTG, you can use the hygrometer sensors of several different manufacturers to measure humidity levels both within and around your hardware. You’ll get a convenient overview of all the current humidity levels, and be alerted by PRTG automatically in the event your threshold values are exceeded.

Prevent costly downtime, and allow partners, coworkers, and clients to work without disruption


An introduction to humidity monitoring with PRTG


How does humidity monitoring work?

Place your humidity-measuring sensors in key locations both inside and outside your server room. Connect the sensors to your network and choose an appropriate transmission technology (such as SNMP or HTTP). Set your threshold values in PRTG, and immediately receive an alert by email, SMS, or push notification in the event of a problem. Eliminate the error before your IT crashes.

PRTG monitors the hardware of suppliers such as:

In addition to humidity, PRTG lets you monitor many other environmental factors in your server room, including temperature, water leaks, fire hazards, smoldering fires, brightness, and windows or doors which have been left open by mistake. Set up your environmental monitoring with PRTG today!
