What are Data Loggers?
To keep it simple, a data logger is an electronic device that monitors the conditions of an environment or an event. This device is used to record and store data over periods of time. Data loggers let you analyze the readings they have collected either via software accessed by plugging a logger into a PC or Mac, or by sending results straight to a Cloud-based storage account so you can access your data anytime, anywhere.
What do data loggers measure?
Data loggers can measure a lot of different information for various purposes. The most common data it collects is temperature and relative humidity. With that being said, they can also record:
- Voltage and/or Current
- Carbon Monoxide
- Carbon Dioxide
- Event, count & state
- Particulate matter pollution
- VOC’s (Volatile organic compounds)
Between the very large amount of data that these devices have the capacity to capture, coupled with all of the different platforms the data can be recorded in analyzed on shows the incredible versatility of data loggers.
USB and WiFi data loggers
Two of the most common connectivity types are USB data loggers and WiFi data loggers. Each type of logger comes with their own benefits, but it very much depends on the needs of the individual as to which type appeals most. Here at Supply Link, we offer both types of data loggers to our customers.
USB loggers, for example, are small scale and easy to operate. Some come with LCD displays so their readings can be seen immediately. Other USB loggers are so simple that they are activated by the push of a single button. Data storage on a USB logger can range from around 30,000 readings to over 1,000,000. Some of them are rugged and weather-proof, allowing for the use in farm outbuildings and won’t be damaged by water ingress or if subject to rough handling.
WiFi loggers, on the other hand, are designed to make life easier by the fact they can be remotely accessed. They have a ‘fit-and-forget’ nature to them which means you can place one or more of them in the desired location, and essentially leave them to it. They can continue to log if the WiFi connection drops out (and catch up the data later on), and alerts can be delivered to your phone or inbox so you never miss a critical parameter breach. Unlimited data readings can be accessed and downloaded via the Cloud.
Data logger applications
As mentioned previously in this article, data loggers are extremely versatile and have a high potential for applications. Here is a short list of a few of them:
- Protection of vaccines in storage
- Food transport safety
- Monitoring indoor and outdoor air quality
- Food processes such as baking or pasteurizing
- Automated temperature checks at medical offices and hospitals
- Keeping dwellings safe from toxic mold.
