ETI Wireless Temperature Monitoring Systems

Wireless temperature monitoring allows users to automate temperature and humidity measurements and review data on a computer or device.

There are two types of data loggers:

USB data loggers

Record temperature or humidity measurements at timed intervals. Readings can be downloaded manually to a computer afterwards for review. Ideal for processes such as cold chain logistics or cook-chill, where readings don’t need to be accessed until the process is complete.

WiFi data loggers

Record measurements at timed intervals and regularly send readings to software via WiFi. Users can stay updated on the logger’s readings 24/7 from anywhere. Ideal for monitoring fridges and freezers for HACP compliance, laboratories, storage rooms and other temperature-sensitive environments.

Whichever process you are monitoring, we have a range of data loggers to suit your application.

Frequently Asked Questions

What is a WiFi temperature sensor?

Wireless temperature sensors are instruments that collect data at programmed intervals and transmit it to a computer using WiFi. This means that instead of manually measuring, recording and storing readings, the entire process is automated. It also allows users to access and analyse the collected data remotely.

What can wireless sensors be used for?

WiFi temperature sensors are designed to be set in place and left to monitor the temperature at programmed intervals. Therefore, they’re best used for room and storage temperatures or humidity.

Common applications include:
• Fridges and freezers
• Food processing, restaurants and supermarkets
• Medical and pharmaceutical applications
• Museums, art galleries and archives
• Zoos and breeding programmes
• Agriculture, livestock and horticulture

Can I receive alerts if temperatures go out of range?

ETI’s WiFi loggers, paired with the ThermaData Hub or ETI Cloud software, will send a notification if temperatures go out of range.

Alerts can be sent to multiple devices. Notifications are triggered at your chosen transmission interval, so you’ll be alerted the next time the logger sends its data.

What are the benefits of wireless temperature monitoring?

• Accurate temperature readings automatically taken on time
• View and manage data remotely from anywhere in the world
• Avoid costly damage with real-time alerts for out-of-range readings
• Validate historical data quickly with an accessible digital archive
• Save time and money on manual labour
• Protect your reputation with a robust and reliable system

How does remote monitoring support HACCP compliance?

Remote systems automatically record temperature data at critical control points. This creates clear, auditable records and helps demonstrate compliance with HACCP requirements.

Do I need to pay for software?

All ETI wireless sensors come with free ThermaData Hub software and no ongoing subscription costs.

Looking for cloud-based monitoring? Our data loggers are also compatible with ETI Cloud software, available from £0 per month.

What’s the best wireless temperature monitor for fridges and freezers?

The ETI Fridge Freezer Wireless Temperature Monitoring Kit is the best choice for cold storage.

High-quality data logger — The ThermaData 2-Channel WiFi Data Logger is designed and made in Britain and built for accurate, long-lasting measurements.
Dual monitoring — Two probes for tracking two fridges or freezers at once. Slow-response probes mimic food temperature for more accurate results.
Free software — Monitor readings remotely, build reports, and get push notifications when limits are exceeded.

Can I monitor multiple locations or fridges at once?

Yes, remote systems allow you to monitor multiple units, locations, or sites from a single platform. This makes it easier to manage large operations and maintain consistent standards.
