Cloud connection

Do you want to check the temperature when you are not at home or in the office or simply not in range of your WiFi network?
That's also possible with WiSpherT°!!!.

Our sensors don't only send temperature within your WLAN but can also upload it to the Internet cloud (server). You can easy access last measurements with your mobile application at any time when you are connected to Internet.

Power supply

Since WiFi communication is quite power consuming, the WiSpherT° doesn't work permanently (to save battery) but makes temperature measurements only in selected time periods, broadcasts results and then goes sleep until next period. The update / broadcast period can be selected in range from 2min. up to 60min. With the two normal AA batteries and update period set to 15min. the sensor can run over 6 months without a need to replace batteries. In case you need temperatures updated often than every 10min. you can connect your sensor to any USB host or power supply and remove batteries. For more details please visit WiSpherT° Technical Specification.

Mobile application

With the WiSpherT° mobile application for Android™ you can easily control all your sensors.
Temperatures can be presented on different widgets together with the measurement time and battery status of the sensor.
The app allows changing following properties of the sensor:

  • temperature units C°/F°
  • sensor name
  • update/measurement period
  • select network connection type to be active for update temperature
The app has access to temperature data from one of our test sensors, so you can fully test it before you decide to buy the sensor.
WiSpherT° app is available at Get it on Google Play


The configuration of the sensor is fast and straightforward. Connect your sensor to your PC using USB cable and run our small configuration software tool. Enter your wireless network name (SSID) and password or key in case the network is secured. That's all!!!.
The sensor will automatically connect to your WiFi network and the mobile app will automatically detect it.
