Description:

The HC-05 Bluetooth Module will be integrated with the Arduino processor to transmit raw data from the biometric sensors to the officer’s phone.

We have established successful communications between Matlab and a webpage we created. Matlab sends processed data from the Bluetooth to this webpage, where the data is visualized graphically in real time. This allows for all of our data to be visualized and serves as a redundant alarm mechanism in dispatch being able to constantly monitor officer conditions. A snapshot of the webpage is shown below.

Building off the capability to communicate between platforms, we have developed a way to send text messages to a cell phone when our algorithm thresholds have been breached by one or more sensors. This is highly encouraging, as it allows for reliable, real-time alerting of dispatch if an officer is in a dangerous situation. It also shows proof-of-concept for our algorithm processing within Matlab. A sample text alert is shown below.

March 4

We have successfully demonstrated contact between the HC-05 Bluetooth Module and a computer-based Matlab program. The Bluetooth is capable of sending signals received from our other sensors to Matlab, where data processing and analysis will occur.

February 15

Initial efforts have focused on proof of concept and the establishment of a reliable connection between the phone and Arduino to accomplish a simple action: turn on and off an LED (setup shown below).

Development will continue with the goal of transmitting physiologically relevant signals to a phone or computer using data obtained from the biometric sensors for further processing.
