Wireless temperature monitoring sends readings from each logger to the cloud automatically, so you can view them from anywhere and get alerts if anything goes out of range. Use the questions below to choose a system, or call us for help planning one.
Tempcon are the exclusive distributor for HOBO wireless temperature data loggers and transmitters in the UK and Ireland. These research-grade instruments are made in the USA and are known for their long-term performance, accuracy and build quality. Looking for wireless temperature monitoring systems for outdoor use? Select 'Environmental (Outdoor)' under 'Typicial Applications'.
How does wireless monitoring work?
Loggers send readings over Wi-Fi, through a gateway, or over the mobile network to a secure cloud platform. You view live and historic data on a PC or phone, set alarm limits and receive email or text alerts. Data is stored on the logger as well, so nothing is lost if the connection drops.
Wi-Fi, gateway or cellular?
Wi-Fi: each logger connects to your network directly, good where Wi-Fi is strong. Gateway: Bluetooth loggers report through a gateway, often the most cost-effective way to cover many units in one building. Cellular: uses the mobile network, ideal for remote sites, vehicles and places with no Wi-Fi.
Is there an ongoing cost?
Some cloud platforms are free for basic use and others need an annual plan, depending on the number of loggers and features such as text alerts and reports. Cellular loggers also need a data plan. Each product page explains what's needed.
What is the range?
Bluetooth loggers typically reach a gateway or phone up to around 30 metres in open space, less through walls. Wi-Fi depends on your network. Cellular works wherever there's mobile signal. We can help you plan coverage for larger buildings.
Can I use it for compliance records?
Yes. Cloud platforms keep a full history and produce reports for audits. Add a calibration certificate for each logger, and choose software with audit trails for pharmaceutical (21 CFR Part 11) work.
Which system do you recommend?
That depends on the number of locations, the Wi-Fi available and how you want to be alerted. Call us with a short description of your site and we'll suggest the simplest system that does the job.
All About Remote Temperature Monitoring

When it comes to reducing waste and improving quality with temperature monitoring systems, remote temperature monitoring offers clear benefits. Also known as wireless temperature monitoring, with this technology you can eliminate the use of cables over long distances and expand the potential for gathering data.
What You Can Get from a Wireless Temperature Monitoring System
A wireless temperature data logger has a wide range of features you can benefit from. These include:
- Convenient wireless setup
- Retrieve data from hard-to-reach locations
- Time & cost savings from not having to travel to the temperature data logger to manually check or download data
- 24/7 online/app access to view, access, and share your data
- Receive automatic alerts via email or SMS text message to your mobile phone when temperatures reach specified high/low points
- Detailed reports delivered automatically to multiple recipients.
With the best remote temperature monitors, you get the above features and others like long battery life and large data storage capacity.
What to Look for in a Remote Temperature Monitoring System
When you’re looking to buy the best remote temperature monitor in the UK, there are things you can look out for to make the best choice. Here’s a quick list to guide you:
- Check that your wireless temperature monitoring system is of industrial/research quality, so that you can be confident it will perform reliably over time. If the sensors or equipment are faulty, it can lead to false reports and serious consequences depending on your application.
- A remote temperature monitoring system should be user-friendly. Without being an expert user, you should be able to monitor, analyse, and export data from your remote temperature monitoring system.
Data Communication
There are four primary ways that wireless temperature data loggers communicate their data:
Bluetooth temperature data loggers – Bluetooth enabled data loggers to use Bluetooth Low Energy technology to transmit data over a 100-foot range wirelessly to a Bluetooth-enabled device such as a smartphone, or to an Internet Gateway device to enable remote temperature monitoring via the Internet.
Cellular temperature data loggers - Real-time monitoring from anywhere with cellular network coverage. Up to 10-minute connection rates via 4G cellular data plans
Radio signal temperature data loggers - transmit data over a 100-foot range wirelessly. Radio temperature data loggers require a receiver connected to a computer or LAN
Wi-Fi temperature data loggers – Some loggers use Wi-Fi. This results in a shorter range, higher energy consumption device, which will usually only be found on devices that are plugged into mains power. Enable remote temperature monitoring via the Internet.
Applications for Wireless Temperature Monitoring
In 2020, when COVID-19 vaccines were introduced, the Moderna vaccine had to be stored at -20°C while the Pfizer vaccine required a cold storage temperature of -70°C. To maintain these temperatures, industrial wireless temperature monitoring systems had to be used.
This is just a single vital application for temperature monitoring systems. Others include:
- Laboratory and pharmacy fridge temperature monitoring
- Monitoring temperature-sensitive goods in transit
- Air & soil temperatures for farms and greenhouses
- Warehouse management
- Food safety and compliance for restaurants and retail
- Food & beverage production process monitoring.
Benefits of Remote Temperature Monitoring
In the UK and the world at large, remote temperature monitoring is of critical importance across many industries.
Temperature is crucial for many products, such as pharmaceuticals, food, crops, and more. So how do you ensure optimum temperature are maintained if not through the use of temperature monitors? With the option of a Bluetooth temperature logger (wireless temperature monitor), you’re able to do this without the use of connecting wires.
This saves time and space and increases efficiency in getting temperature data.
The best remote monitoring systems also go beyond a basic temperature reading to include optional benefits like monitoring: humidity, CO₂, open/closed doors, ambient light, power outages, pressure differentials, flooding or water leaks, and more.
With your remote temperature monitoring system, you can experience greater efficiency, fewer compliance issues, and make better decisions with your application.
