BLE-RSensor Bluetooth tag for resistance based sensors

Logos-t battery assisted passive temperature sensor


The BLE-RSensor can be considered as a Bluetooth sensor development platform for resistance based sensors such as thermistors – for temperature sensors – or light dependent resistors (LDRs) – for ambient light sensors. You can monitor resistance values from 10Ω to 10MΩ with the Bluetooth resistance sensor, with accuracies of ±1% in the 100Ω to 1MΩ range and ±15% in the 10Ω to 100Ω and 1MΩ to 10MΩ ranges. The BLE-RSensor works with Bluetooth 4 devices. You can download the free demo application to monitor resistance and/or log resistance values. Get the Bluetooth RSensor demo app for:

  • Windows (Windows 8 onwards) Icon with SW
  • Android (Android 4.3 onwards) Icon with SW

This Bluetooth based sensor development platform features a button/LED manual interface and can easily be reset. It works on a standard CR-2032 button cell lithium battery with a battery level monitor that alerts the user through both the Windows and Android apps and the board itself.
