Data Loggers

Data loggers record measurements over time, from any kind of sensor - temperature, humidity, pressure, electrical power etc.

Temperature / Humidity Loggers

Data loggers for measuring and recording temperature and/or humidity only

Electrical Power Loggers

Data loggers for measuring and recording electrical power: AC voltage, current, kW, power-factor etc

General Purpose Data Loggers

Data loggers designed for general purpose use, supporting multiple different sensor types

Specific Purpose Data Loggers

Data loggers designed for specific purposes, including mains power monitoring, pressure, time-of-use, etc

A data logger is a battery-powered, compact device that records measurements over time. It contains an internal microprocessor, one or more sensors or sensor ports, and data storage. You’ll find a broad range of quality data loggers at Esis, and they’re excellent for personal or business use. You can deploy your USB data logger in a range of environments to record your measurements at set times for years without having to attend to them.

Depending on the type of data logger, your measurements can include relative humidity, temperature, differential pressure, AC/DC  currents and voltage, kWh energy usage, light intensity, water temperature, time-of-use for motors or lights, water level, soil moisture, dissolved oxygen, wind speed, rainfall, wind direction, pulse signals, leaf wetness, plug load, room occupancy and much more.

Data loggers can be small single channel units, multi-channel data collection units or a stand-alone device that fits neatly into the palm of your hand. They all use some type of sensor, either external or built in. While most data loggers are designed for long term repeated use, some small temperature data loggers are single use or single trip, suitable for monitoring sensitive shipments. Single trip loggers can be helpful as the receiver does not need to ship the logger back to the sender each time goods are received.

How Do You Use a Data Logger?

No matter the type of data logger you choose to get, almost all function much the same way. You’ll use accompanying configuration and graphing software to connect to your data logger. The software lets you configure settings such as how and when to start it, which sensors to use, and how often to take measurements. Then, you deploy your USB data logger to the location you want to monitor. The logger will start recording every time-stamped measurement you set and store it so you can look back at it later.

After your data logger works for your desired length of time, you can connect it to your computer and use the software to download and analyse your data. You’ll get a readout with data and display measurements in graphs that give you the area’s profile over your set time frame. You can check tabular data and export everything out into spreadsheets as well.

Hence the six steps for using a data logger are:

  1. Download the logger software and install it into your laptop or device. 
  2. Connect your USB data logger and set your chosen parameters. 
  3. Take your data logger out to your desired location and set it up to record your data. 
  4. Leave the data logger to record for the desired amount of time.
  5. Reconnect your data logger to your device either through USB or a mobile device. 
  6. Download your data and analyse it with the included software. 

Another style of data logger becoming more popular is the wireless data logger. These data loggers can eliminate the manual steps of bringing the data logger to the PC to unload the data regularly. Instead the data logger stays connected wirelessly all the time, sending its recorded data to your PC or to a cloud service. In addition to saving the effort of manually unloading the data, wireless data loggers have the amazing benefit that they can instantly send you alerts of unexpected conditions. For example if your data logger is monitoring fridge temperature, and the fridge temperature starts to go higher and higher indicating a fault, you will be notified immediately. This means you can save your refrigerated stock from being ruined. Much better than having to throw out stock because you only discovered the problem 1 week later when you downloaded the data from your logger!

What do I need to consider when choosing a Data Logger?

There are so many different types of data logger on the market, it can be confusing to figure out which one is best for your application. Options to consider include: Built-in or External Sensors, USB / Serial / Ethernet Connections, Wireless via Zigbee / WiFi / 4G / Cat.M1, Battery / Mains / Solar power, LCD / LED Displays, Waterproof IP Ratings, Memory capacity, Math calculations, Single Use or Multi-Use, Alarms, Calibration Certificates, etc.

To make it easy for you to choose, simply contact Esis and tell us what you want to achieve. We’ll ask you some questions, and figure out which products are the best options for you.

Questions we’ll ask include:

  • What are you trying to achieve once the data logger is up and running, ie. what is the overall goal?
  • What do you need to measure, e.g. temperature, humidity, electric power, electric energy usage (kWh), pressure, water flow, etc
  • What range of measurement do the sensors need to cover? eg. temperature -20 to +60C
  • What accuracy do you require? (Note that high accuracy sensors and loggers are often much more expensive)
  • What environment will the sensors and data logger be in?
  • How often do you need to take measurements? (ie. sampling interval)
  • How often would you want to download data from the data logger? Or do you want it connected up all the time for real time results?
  • Do you need remote access to the data without having to visit the site?
  • How will you power the data logger? (mains, existing DC, battery, solar etc)
  • Is a specific calibration certificate required?

Expert Support Can Be Critical
