Tip: The Importance Of Baselining For Setting Up Your Device

Written by TempAlert

Often we receive inquiries about our recommendations for the appropriate temperature thresholds to set. However, at TempAlert we know that every room or refrigerator has its own microclimate (even sensors inches apart can read different values). Although similar applications might share the same temperature threshold range, every location is unique. So how does one figure out the correct range?

Essentially in order to determine the right thresholds for your environment, you need to acquire adequate baseline knowledge. This process is called "baselining", which involves monitoring the room or refrigerator first to establish a history of normal conditions.

To begin, set up your TempAlert device to start recording temperatures. Next, determine the amount of time needed for temperature collection. Depending on your application, this could vary significantly. For instance, server rooms, refrigerators and freezers change temperature very quickly. Running the baseline for a few hours is usually sufficient. Whereas items with large thermal mass, such as a house, change temperature much more slowly and base lining may require 12-24 hours. By adjusting the time of the base lining activity your device can pick up any deviations from the norm caused by compressors, sunlight, air conditioners and other environmental factors. After reviewing this data set, you'll see the natural highs and lows of the environment. Using this data, you can then setup appropriate thresholds to more accurately reflect real world conditions and reducing false alarms

By following this method, you will achieve the proper range for your TempAlert devices. If you have any questions please e-mail us at [email protected], we're always here to help!
