Manually checking temperature gauges and noting them down on a loose bit of paper temporarily fastened to a clipboard has long been the norm. Those jotted down numbers are then often entered into a spreadsheet or online database and sent on to relevant teams and individuals within a business. This system is better than nothing but it has many problems.

20 or 30 years ago, when spreadsheets were introduced, this was seen as a cutting edge process. But not any more. Now, with the rise of IoT (Internet of Things – internet-connected sensors), there’s a new way and many businesses are taking full advantage to save money, improve safety and ensure compliance. 

Temperature sensor technology has been used in manufacturing, facilities and hospitality for a while. However, it’s impact has become even greater with the addition of IoT which has increased their influence and use cases, offering unprecedented connectivity, automation opportunities and analytics to benefit your processes.

Use Cases

1. Preventing Legionella

As recently as 2018 there was an average of 350 reported Legionnaires disease cases in the UK. Of course it’s formed from an infection when Legionella bacteria is found in soil or water and high risk environments include washrooms, air conditioning units, pipes and cooling towers. To reduce the risk in water systems temperature needs to be controlled and sensors are the solution. With the wireless solution in place, preventative monitoring and reporting is easy and will help protect your businesses. 

Pipe Monitoring: Reduce the need for labour-intensive monitoring by tracking water movement and temperature automatically. All you need to do is connect sensors to taps, boilers, pre- and post-storage tanks and plug in a cloud connector so it all feedback to a central platform. Access reports generated at the click of a button, and ongoing insights which send preventative alerts when temperatures fluctuate unexpectedly. Furthermore, when sensor data is synced with a system such as OpsBase, these alerts can trigger workflow actions so that proper process is followed and documented (for easy auditing).


  • ROI within 6 months
  • Save 600 litres of water per tap
  • Reduce carbon by 2900kg with up-to 12 engineers car trips saved

Smart and Safer Washrooms: Clean only when you should based on usage and customer feedback and know how crowded they are for safer practice. A range of connected sensors in various spots such as urinals and cubicle doors means needless cleaning is eliminated and issues can be reported and solved quickly. Again, syncing data with a digital operations system like OpsBase means that you can automate the task of assigning work actions to the correct team as required – saving unnecessary effort where usage is low.


  • ROI within 6 months 
  • Save £15k on cleaning costs per 10 bathrooms

2. Cold Storage and Transported Goods

Some items are required to be stored in carefully temperature-controlled environments due to their sensitivity to humidity and temperature. The latest critical example of this is with the potential new Coronavirus vaccine which needs to be shipped and stored at -70 Celsius. Other products stored in a standard warehouse can also be affected by corrosion. Freezers and heaters are used to maintain warehouse temperatures ensuring the quality of specific products is optimum. Managers use sensors to monitor temperatures and adjust if they need to, in turn reducing costs for inspections and maintaining the consistency of their products. This is all true for food safety too, where maintaining a stable storage temperature is required for consumer health.


  • ROI within 4 months
  • Improved safety and robust audit trails for compliance
  • Reduced waste and better energy efficiency
  • Perform preventative maintenance to avoid break-downs 

Transported Goods: One of the most crucial aspects of the supply chain is the connection between manufacturers, distributors and consumers. During distribution, temperature margins are critical and can affect products because the environment is constantly changing during the journey. Therefore specially developed cold storage containers are used to ship such goods in the correct environment for the product. With the use of temperature sensors, businesses remotely monitor the environment in real-time and are able to make immediate adjustments to maintain product quality.


  • Continuously monitor goods with no breaks
  • Receive immediate alerts when problems arise
  • Works with your predictive maintenance strategy so equipment is serviced before it breaks
