The Best Server Room Environmental Monitoring Software Systems & Tools (Temp/Humidity)
UPDATED: February 12, 2024
Monitoring the environmental state of a server room or data center is often one of the most overlooked but essential practices to ensure system uptime.
A Forrester Survey report called “The State of IT Resiliency and Preparedness” showed that the top five leading causes for downtime are power outages, Hardware/Software/Network failures, human error, hurricanes, and floods. The same report revealed that downtime hurts the most critical areas in a business. It can hurt productivity, loss of opportunities, the employee’s morale, and a big loss in transactional revenue.

In the following Server Room Environmental Monitoring Tools & Software article, we will take a closer look into the most popular tools to monitor internal components and external environmental factors in a server room.
Why is Important to Monitor The Server Room?
A handful of blade servers can produce large amounts of heat, which can affect the overall temperature of the server room. It is essential to keep track of their temperature. A simple failure in a Heating, Ventilation and Air Conditioning System (HVAC) or voltage systems can lead to a disaster in a data center.
Unfortunately, the temperature is not the only environmental factor that can impact servers in a data center. Other conditions such as humidity, water leaks, smoke, lack of airflow, peaks/drops in voltage, and theft can also impact the server room.
The Conditions That Could Affect a Server Room
How can temperature and humidity impact the server room?
- When the temperature is too high, it can damage servers. Overheating can lead to permanent damage.
- Although low temperature should be pursued to maintain server’s uptime, it can get costly in terms of energy consumption. Rapid changes in temperature (from hot to cold, or vice-versa) should also be avoided because they can cause condensation. Extreme cold can also lead to dry air, which leads to static electricity.
- When the humidity is too high, it can lead to water condensation, which creates hardware corrosion and failure in electronic components.
- When the humidity is too low, it can cause electrostatic discharge (ESD), which may damage sensitive electronic components.
Without a doubt, water leaks are also one of the leading causes of downtime. They can be caused by weather intrusion, cracked pipes, or clogged drain or drain pan from HVAC systems. Peaks or drops in voltage can also disrupt equipment and create power outages. It is critical to monitor power to avoid outages, failure, and over-consumption.
Maintaining the recommended environmental levels such as temperature, humidity, power, and avoiding water leaks at all costs within the data center can ensure overall reliability and uptime.
Server rooms can be monitored through internal or external sensors. An internal sensor, monitors component within a single device, it could be its fan speed, temperature, voltage, etc. Almost all computers and processors come with an integrated internal sensor which helps collect information.
External sensors, on the other hand, collect information from the server room environment. They can be located on the cabinets, rack-mounts, and their job is to keep an eye on the entire room. External sensors range from smoke detectors, thermal and humidity sensors, airflow, water leakage, etc.
Some of the following tools and software showed next can monitor single devices with internal sensors, while others can monitor entire rooms through external sensing.

1. tempCube – EDITOR’S CHOICE
Not every server room has available power points all around and you will need to trail extension cords around the room to get temperature sensors in strategic locations. You can solve this problem with tempCube, which is a range of wireless, rechargeable environment sensors.
The standard unit comes with a holder that can be fixed to the wall. The unit slots into this but you can also remove it to take it to a charger – removing the need to trail extension cords around the room. The sensor can also be placed on top of cabinets or on table tops.
Each unit has a display screen but you probably won’t want to have to sit in the server room and watch them. The tool sends out a constant stream of readings over WiFi, so you can collect the data and channel it through to your workstation.
The tempCube system comes with a free mobile app for iOS and Android. You can get data sent to that app as well as to your desktop computer. The creator of tempCube, Nimble Wireless, also provides management software that collects the data sent out by multiple sensors. The dashboard will send out an alert by SMS or email if pre-defined temperature thresholds are crossed. Visit tempCube – this device has been reduced and is now offered at $49
EDITOR'S CHOICE
tempCube is our top pick for a server room environmental monitoring system because it provides the constant recording of both temperature and humidity in its immediate vicinity. This is a portable unit that is rechargeable, so you don’t need to limit the location of each sensor to the vicinity of a power socket. You also don’t need to run an ethernet cable to the unit because it connects to your WiFi system. Place several sensors around the server room to get a comprehensive report of room temperature. The package includes a software tool that interprets readings from multiple monitors and sends out an alert by SMS or email if acceptable temperature or humidity levels are crossed. The supplier also offers a free mobile app for iOS and Android.

Summary
Electrical outages, floods, failures in hardware, broken HVAC systems, human errors, are downtime accidents that are difficult to prevent. Although some high-end data centers can reach 99% of uptime, there is still the 1% that hurts the business.
System admins often forget it, but the server room and data center environment are one of the critical factors for successful uptimes. Monitoring temperature, humidity, and other climate factors can lead to less downtime and higher reliability.
Some of the server room monitoring tools showed above can help you keep track of the heat and fan speed within a single server. Others can monitor the entire temperature for every device on the network. And other tools with the help of external sensors can watch the whole server room.
