The Quanser Mechatronics Sensors Trainer USB Barometer Humidity Page plots the humidity measured by the BME280 weather sensor as a percentage. The page is depicted below with a sample plot:

The settings page is common to the pressure, humidity and humidity provided by the BME280 weather sensor. The settings are illustrated below:

To skip the humidity measurement, set the Humidity oversampling to Skip. Otherwise set it to one of the oversampling options to both enable the humidity measurement and determine the amount of oversampling performed. Higher oversampling will reduce the noise but will add more lag to the measurement.

The humidity measurement does not support the IIR filter. Hence, the humidity resolution is fixed at 16 bits and the Filter coefficient setting has no bearing on the humidity measurement.

The Inactive duration setting determines the output data rate of the sensor. It is the time between readings and affects the pressure, humidity and humidity readings.

Tap the close button in the top, right of the page to apply the new settings and return to the plot.
