New here, looking for some help

[mgenin14]

Hi there! I am relatively new to this world and I need some help with a simple project.

I'd like to develop a wearable prototype that measures the plumb alignment of the human sternum in real time. The device would be worn in something similar to a chest strap located at the bottom of the sternum. The goal is to help users maintain safe body positioning by detecting misalignment and providing alerts via bluetooth and/or built-in speakers.

As someone new to coding and hardware development, i'm seeking guidance in what could be the ideal hardware components for this.

I have the following components:

- Adafruit 9-DOF Accel/Mag/Gyro+Temp Breakout Board (LSM9DS1) sensor
- Arduino Nano 33 BLE Sense Rev2
- ESP32
- 3.7V 400mAh rechargeable Li battery

And my first question is - Should I be starting with components more suitable for the goal? Is there a way I can simplify this? I really just need something that indicates angle of sternum to horizontal and can send alerts via bluetooth and/or built in speaker.

Thanks so much for any insights, thoughts, advice !

I'd start prototyping with the Adafruit Glasses. It has BLE and a triple access LIS3DH accelerometer. It is also small and takes a battery. You can immediately link up with Adafruits Bluefruit LE Connect app and be sending alignment data. You can also plug in a small Lipo. I like the 350mA Lipo due to default charge rates, cable length, size and weight.

If you really need a 9-DOF with gyro then use the Adafruit Sense.
