Week’s Accomplishments:

 

This week we started to develop our mobile application for our project. We’re using a backend framework  and cloud storage called Firebase (www.firebase.com). This will save us a lot of time because we will not need to develop our own backend REST API.

 

We are also using a project management system called Trello( www.trello.com). Using this tool we can keep track of our work and schedule our next steps.

 

We finally bought all the hardware that we will need for our prototype, it included:

• Arduino pro Mini 328 – $10,00
• Accelerometer ADXL 335 – $15,00
• Bluetooth device – $25,00

 

Problems:

We were planning to use a pulse sensor, but we figure out that most of them just works when you put the device on the tip of the finger or the device required a really precise position at the wrist to work.

Due to this problem we decided to change the pulse sensor for an accelerometer to detect falls. We are planning to detect when someone falls and stay on the floor for more than 10 seconds, if it happens we will send an alert e-mail at the same way as if someone had pressed the button.

 

Next week:

We are planning to finish the basic features from the mobile application and if the hardware arrives we will test if everything is working fine making sure that we can do everything that we want.
