Engineering Requirements

ER1.1.  Use GSR, EMG, pulse sensors and set thresholds from the analog signals that indicate when there is a noticeable change in emotion

ER2.1. LED turns on that is visible on the wearable when all 3 thresholds are passed simultaneously

ER3.1 Place sensor(s) on body parts that give optimal measurements

ER3.2 All sensor data within 5% accuracy

ER4.1 Use cell towers(GSM) to articulate location of device

ER4.2 Microprocessor will determine when all 3 sensor thresholds change, to send data of location to the cloud

ER5.1 Wireless connection through Photon Particle device

ER5.2 Use sim card through a cell-phone carrier to provide wide-range network

ER6.1 Sensor data will be processed in the database to be plotted on the cloud

ER6.2 Plots will show when sensor thresholds are passed and where the user was when these spikes happened

ER7.1 Server has enough storage to store up to 2 years of continuous data on it

ER7.2 After each week, average data points to store in database to make more room for more data

ER8.1 Use Raspberry Pi for server which can be accessed by public

ER8.2 Multiple pages available for each client’s data

ER9.1 Check if authentication is provided before viewing data for each individual

ER10.1 Using low-power microcontroller so battery will last for 8-10 hours

ER10.2 Recharge battery using charge controller

ER11.1 Device diameter of 2” w/ either elastic or clasp band

ER11.2 Complete device weight should be 5 oz or less

ER12.1 Insulated wiring

ER12.2 Proper packaging keeps all wiring, sensors, and power supplies protected
