+# Sensible
+
+Collect all the sensor data from the Bangle.js 2, display the live readings in menu pages, and broadcast in Bluetooth Low Energy (BLE) advertising packets to any listening devices in range.
+
+
+## Usage
+
+The advertising packets will be recognised by [Pareto Anywhere](https://www.reelyactive.com/pareto/anywhere/) open source middleware and any other program which observes the standard packet types.  Also convenient for testing individual sensors of the Bangle.js 2 via the menu interface.
+
+
+## Features
+
+Currently implements:
+- Accelerometer
+- Barometer
+- GPS
+- Heart Rate Monitor
+- Magnetometer
+
+in the menu display but NOT YET in Bluetooth Low Energy advertising (which will be implemented in a subsequent version).
+
+
+## Controls
+
+Browse and control sensors using the standard Espruino menu interface.
+
+
+## Requests
+
+[Contact reelyActive](https://www.reelyactive.com/contact/) for support/updates.
+
+
+## Creator
+
+Developed by [jeffyactive](https://github.com/jeffyactive) of [reelyActive](https://www.reelyactive.com)
