The Senzor app is useful and simple application which collect data from five sensors in your device:
• Accelerometer,
• User Accelerometer,
• Gyroscope,
• GPS,
• Barometer.
You can see actual data from sensor on dashboard in a time interval of your choice.
The biggest advantage of this app is the fact, that you can sending data from sensors in real time to your web server over the HTTP (using POST request) or Web Socket protocol. I prepared Raspberry Pi web server demo for better understanding how can you collect data from sensors on server-side. You find these examples for Tornado and Flask microframework on address: https://stanislavrevay.com/sensorsUserGuide.html
This app really helps me during my study while I creating server for collecting data from sensors and I hope that app will helpful also for you.
Please write me your experience as an app review.
