Requirements

Table 1: Requirements for the Unit
Req.	Description	Priority
1	The mass must be determined using the HX711AD load cell via Arduino and Simulink.	1
2	The measuring range must be determined.	1
3	The measurement uncertainty (1σ) must be determined for the measuring range and displayed as a confidence interval.	2
4	The `on/off` button starts the system. The sensor must first be calibrated and display 0 g.	1
5	The weight must be referenced for the measuring range.	1
6	The measured values must be filtered/smoothed over time.	1
7	A beep must indicate when the measured value is stable/constant.	1
8	The sensor system must display the weight in g on a display.	1
9	The `tara` button resets the current weight to 0 g (recalibration).	1
