Project Budget

Hello,
This post is just going to be the breakdown of the costs of the project.

Arduino

This category consisted of only the Arduino Uno board which we are using to record and analyze data from the sensors

Sensors

The sensor used was a small pulse sensor that clips onto the user's ear. More details on this sensor can be seen on our week six blog post. We also tested out a sensor that strapped onto the user's arms and legs. Each of the sensors cost about $25, but only one was used in the final design so only one's cost was factored into the budget. 

Connectivity

We used a HC-06 Bluetooth module to allow the device to connect to smartphones and computers wirelessly. 

Peripherals

Since the main purpose of the project was to notify users of heart rate abnormalities, we needed a way to convey an alert message to a user. We used a LCD display module and a simple speaker for this. 

Miscellaneous

This category included all the wires and the breadboard used to connect all of the components. We also bought a pack of switches for the kill-switch function on the device. Since the device is meant to be carried around, we needed a rechargeable battery pack to keep the device wireless. We also got antistatic bags to protect the device when the user is wearing it. Mike's dad was kind enough to give our group a waist pack (fanny pack) to carry our device around in.
