Wireless temperature loggers measure and transmit temperature over Bluetooth Low Energy. You can use a free mobile application to configure the device and read the data from its memory. If you add Efento Gateway, you can build a remote temperature monitoring system for objects which need supervision such as medical refrigerators or pharmaceutical warehouses. The logger is equipped with an external, waterproof probe.
