Wireless temperature monitoring set - Bluetooth Low Energy

The system consists of a base station (a smartphone with Android 4.4 or newer and equipped with Bluetooth 4.0) with a display, and wireless sensor that communicate with the station. The application installed on the base station stores temperature measurements and sends SMS/email notifications on exceeding temperature thresholds that define the safe temperature range.

  • Temperature: -35 to +70°C, accuracy: up to 0.4°C in the range from -20°C to +70°C and up to 0.5°C in the range -35 to -20°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
