Pressure Sensor Testing

We tested the MPX5100A pressure sensor by placing the device in the same room as an analogue barometer and reading both measurements, and by placing the device outside and looking up the barometric pressure of our area online. Our results are below.

	Expected	Measured	%-error
Weather.com	100.6 kPa	100.0 kPa	0.6 %
Classroom Barometer	94.8 kPa	98.8 kPa	4.2 %

We feel that the percent difference is higher when compared to the analogue barometer because the analogue barometer is old and probably hasn’t been calibrated in a while. We are still confident in our results to send the sensor up with our payload
