6. Our Solution Strong as a Buck ▪Measures force ▪User friendly ▪Easy to read display ▪Store measurements into memory

7. Technical Constraints NameDescription Force CapacityThe device must be able to withstand 683 pounds (lbs) of force. Battery LifeThe battery life of the device must be 1-1.5 hours. Conversion RateThe analog-to-digital converter (ADC) must have a conversion rate of 9.6 kilohertz (kHz). AccuracyThe device must account for ± 5% of combined error of output of the load cell. MemoryThe device must have 1 gigabyte (GB) of flash memory in order to provide ample memory space for the saved data.

8. Practical Constraints Environmental Must not damage the facility Must not harm the deer Must be mobile enough to move in and out of the pens

9. Practical Constraints Sustainability Must maintain sufficient structural integrity Must be durable enough to be used for repeated application.
