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 hospitals, cell banks or pharmaceutical warehouses. The logger is equipped with a waterproof probe with a Pt1000 sensor which has a very high accuracy in low temperatures.

• Temperature: -200 to +200°C, accuracy: up to 0.5°C in +200°C and 1.3°C in -200°C
• Measurement period: 1 minute – 10 days (configurable by the user)
• The device stores 40,000 measurements in its memory, when the memory is full, the oldest measurements are overwritten
• Battery ensures up to 5 years of maintenance-free operation
• Add Efento Gateway and Efento Cloud to build a real time monitoring system.  The maximum distance between the sensor and the Gateway is 100 m in the open space and 20 – 30 m in the buildings
• Use a free mobile application to configure the logger, read the data from its memory, generate reports and set alert thresholds
