Function and Applications
All-in-One Sensor for wireless data acquisition via Bluetooth 4. Suitable for tablets (iOS and Android) and Smartphones (Android) in combination with the free App PHYWE measure.

This sensor enables real-time temperature measurement with graphical progression for the investigation of temperature-dependent processes, which can also continue over a longer period of time. The water resistance ensures the longevity of the sensor even in experiments with liquids.


  • All-in-One device, no interface needed
  • Plug & Play: Just switch on and start to measure
  • Latest technology: Bluetooth 4
  • Perfectly tuned to PHYWE student experiments
  • Automatic sensor recognition
  • Excellent price-performance ratio
