Wireless Temperature Sensors

Switch to a wireless temperature monitoring system with WiFi temperature sensors. ETI’s wireless temperature and humidity loggers enable users to automate the temperature monitoring of fridges, freezers, storage facilities, buildings, and much more. 

The ThermaData thermometers will take the readings at programmed intervals and wirelessly transmit the data to a computer or device using WiFi. Users can then view and manage the data remotely and receive real-time alerts when readings fall outside their limits. 

ETI offers different types of remote temperature sensors for a range of applications. This includes temperature data loggers with internal sensors designed for buildings, humidity loggers for storage, and pharmaceutical loggers for vaccines and medicines. Read more below to find out how our WiFi thermometers work and which one is best for you.

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.

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
• Zoos
• Agriculture

• 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

All ETI wireless sensors come with free software and no ongoing subscription costs. Learn more about ThermaData Studio software here. 

What’s the best WiFi temperature sensor for me?

Room Temperature Monitoring

With one internal sensor, the ThermaData TD is great for monitoring the ambient temperature of warehouses, storage facilities, laboratories, offices and public spaces.

Fridges and Freezers

Wireless temperature sensors need to be placed outside of fridges and freezers to maintain signal, so external probes are best. The ThermaData TD2TC has two thermocouple channels for pairing with a variety of probe types. We recommend a Food Simulant probe for fridge monitoring. 


Accuracy-Sensitive Applications

For applications where greater accuracy is a priority, the ThermaData TD1F and TD2F thermistor loggers have a higher system accuracy than the TD2TC thermocouple logger. Their permanently attached general purpose probes make them ideal for a wide range of applications, including fridge/freezer monitoring.

Hospitals and Pharmacies

Medicines and vaccines are slower to respond to temperature changes than the air inside a fridge or freezer. The ThermaData Pharm features a glycol-encased probe which matches the response rate of medicines and vaccines for more accurate readings. 

Humidity and Temperature

Perfect for museums, zoos and grain storage, the ThermaData HTD monitors humidity and temperature simultaneously. Opt-in to receive instant alerts for readings outside your programmed limits — take corrective actions more quickly and prevent costly damage.
