Displaying Sensor Data with Bluetooth

Pick Your Display Method

For this tutorial, you are able to choose how you would like to display your data from the KX132 Triple Axis Accelerometer.

Option 1: Display Data on an OLED

Following the instructions for Option 1 will teach you how to view accelerometer data on an OLED attached to the client ESP32 board. You will need two ESP32 Thing Plus C boards, a KX132 Triple Axis Accelerometer, a Micro OLED Breakout(Qwiic), a USB A to USB C cable, and a power supply. Again, we recommend using the Lithium Ion Battery with JST-PH Connector for the server ESP32 board’s power supply. However, there are a variety of power sources that will work with this application.

Option 2: Displaying Data With a Python Graph

Running this Python script with the sensor connected via Bluetooth generates live-updating graphs, providing a visual representation of the accelerometer's data. Although this is a basic template, the live updating plot offers an excellent way to simulate a dashboard experience without needing to purchase a license, while also allowing for personal customization.

Option 3: Display Data on your Mobile Device

Following the directions for Option 3 will show you how to display accelerometer data on your mobile device through a BLE app. For this section of the tutorial, you will need an ESP32 Thing Plus C board, a KX132 Triple Axis Accelerometer, and a USB A to USB C cable.
