What can BLE Sensor Beacon be used for?

In previous embedded development, sensors often required cables to be connected to the controller. If you want to place sensors in locations that are a little far apart, the wiring becomes a little more difficult.
With BLE Sensor Beacon, you can think of it as a small controller that can connect numerical/analogue/I2C sensors. And connect it with your Bluetooth mobile phone or Bluetooth controller (e.g. ESP32) to design your own sensor node.
