Hardware components we have assembled
Prototype with Arduino No. 1
This prototype uses an Arduino Mega 2560 that powers and controlls the LoRa transmitter to send the location data and concussion data.
The gyroscope we are using
MPU-6050 gyroscope has six degrees of freedom, and we can implement Kalman filter on chip, which will give us very stable and accurate data.
A picture of LoRa chip
LoRaWAN provides a solution for low power, long range, and low bandwidth communication, which is exactly what we need for our application.
The second prototype as a transceiver
Another Arduino that collects data before we purchase the LoRa Gateway. LoRa Gateway will be used to communicate with our LoRa chips, and act as a medium to the Internet. It will significantly improve our signal range.
PCB we have made
We are trying to build our first beta prototype that can actually be installed on a helmet.
