Engineers Patrick Slade, Mykel J. Kochenderfer, Scott L. Delp and Steven H. Collins Stanford University Published a paper this week detailing their raspberry pieBased on fitness tracking items. Using Raspberry Pi 3 B+, the team developed a more accurate method to track how many calories your exercise actually burned in real time.
According to the team, their Pi-based system can provide more accurate output than commercial smartwatches at a lower cost.This The best Raspberry Pi project You can make it yourself, and engineers open source this project to any manufacturer interested in recreating their work.
When it comes to the Raspberry Pi project, the hardware used is very basic, totaling about $100.
The engineer chose 3 B+ with one help Adafruit Perma-Proto HAT Provide power for operation. A battery is required to move the device. These components are mounted on the belt around the user’s hips.
In addition, two sensors are connected to one leg and provide the real-time input required by the Pi. The leg sensor is an inertial measurement unit connected to the TCA9548A multiplexer mounted on the Perma-Proto HAT. The user wears one on the thigh and the other on the calf. Together they measure the acceleration and rotation of the leg as it moves.
The data is compiled to determine things such as whether the user is resting and how much energy they consume.
