What should one consider before placing their temperature/humidity sensor? Location, Location, Location!
In order to even set up your thresholds for your Temperature@lert device, one must study the space of their server room and consider the components within it. This process is what we had previously dubbed as "baselining," which should be done so that you can determine the proper ranges for temperature and humidity. So what spots are the most critical for consideration when it comes to sensor placement?
1. Hot Spots
At the bare minimum, place at least one sensor in a central location in the room. Note that every room has its own mini weather pattern and conditions from one part to another can vary based on what the room contains and where vents/returns are located. The simplest rule of thumb is that heat rises. So, the higher the sensor placement, the warmer the temperature. Locating sensors near walk-in doors will also show warmer readings due to the influx of room temperature air when doors are open.
2. Cooling Vent Locations
Whether it is an air conditioner, economized cooler or another chilling device, it will affect the sensor reading depending on proximity of the sensor to the vent. If you want to monitor whether your cooling unit may be going out at different times, place a device in the air duct and you can determine when the cooling unit is off. Too close to the cooling unit will cause the sensor to pick up when your cooling unit is cycling and you'll get false-alerts when it cycles to off.
Besides cooling vents, you need to consider hot vents too from server cabinets or compressors. Placing a sensor near there or in between these areas can help one monitor when it gets too hot before a shut down occurs and causing a loss of data and revenue for your company. High temperatures can also cause damage to hardware.
4. Ancillary Humidification Systems
These systems help control humidity. Too much humidity can cause condensation, which leads to electrical shorts. Not enough humidity causes one to have quite the mini-electrifying experience with static electricity at its peak. Place your humidity sensor in a place that is not too close to the ancillary humidification system in order to prevent the sensor from getting shorted or getting a false overly-humid reading.
By monitoring temperature and humidity, one can have early warning of any pending disasters.
