What is a Data Logger?

what is a data logger and how can it be used in a data logger suite?

Data loggers are devices which instantly keep track of, as well as record, ecological parameters over time, allowing conditions to be measured, recorded, evaluated as well as validated. The data logger contains a sensor (or sensors) to obtain the data and an ultra-energy-efficient system on a chip to process, save, and transmit the collected data. The information recorded in the data logger can then be accessed directly or wirelessly sent through 4G mobile networks or utilising satellite.

Most commonly data loggers are designed as a stand-alone device that can read various kinds of sensors and store the data in internal memory for manual retrieval. This can prove problematic due to many factors such as the man-hours required and accessibility to remote sites. However, Ontoto’s data loggers transfer autonomously by design, with onboard data storage as a redundancy measure. All of our data is accessible via our Ontoto Web Portal; emailed; linked CSV files and our easy to use API.

The advantage of Ontoto’s data loggers is they can run individually for up to 5 years on a single, easily replaceable battery pack. Our range of loggers retrofit into any standard site monument, and are compatible with a wide range of sensors, with support for multiple sensors on one data logger device.

Where are data loggers used?

what is a data logger & what are they used for

Data loggers are used for a vast array of applications in a wide variety of sectors worldwide. These consist of, for instance:

  • Ecological and Environmental Research: environment change, climate patterns, seasonal changes, wild animal habitats, waterways, and oceanic studies.
  • Buildings and Facilities: monitoring power usage, heating, and ventilation conditioning systems in buildings, storage facilities, commercial facilities, etc.
  • Food Industry: the preparation, storage, transport, and display of food.
  • Laboratories: sterilisation procedures, cryogenic applications, environmental protection. transportation of medical supplies and clinical equipment,  clinical refrigeration.
  • Logistics Sector: monitoring temperature and moisture levels during storage and transport, monitoring hazard analysis, and critical control points (HACCP).
  • Agriculture and Horticulture Industries: monitoring growing conditions, storage facilities, transportation, animal health, and wellness conditions, .
  • Production: procedure applications, environment monitoring, power supply, facility monitoring.
  • Museums and Galleries: screening and transportation of delicate items, artifacts, and archival storage and monitoring.

Why are data loggers needed?

Many industries are governed by government regulations and industry standards that stipulate certain criteria that must be monitored and reported. Data loggers are a tool that can provide this monitoring and reporting.

An example of this is the food industry.  From the preparation of food items to the storage and transportation, temperature and moisture levels must be recorded throughout the processes and that data made easily available.  Data logging provides overall traceability and reporting to ensure a company maintains compliance.

Data loggers can also help organisations become more efficient and economically viable.  Gathering the data on the heating and cooling of buildings can highlight the inefficiencies of heating, ventilation, and air conditioning systems and provide a way to improve the systems.  This in turn would lead to better environmental outcomes as well as financial.

There is a wide variety of parameters a data logger can measure: energy, temperature, humidity, CO2, solar radiation, wind speed, vibrations, water levels, to name just a few.  The industries in which they can be used are endless.

 A small device can provide significant data to achieve big results.
