To go back to the Sensors page, tap on the close button in the top, right corner of the page. To change the sensor parameters, tap on the hamburger menu in the top, left corner of the page. This will open the settings screen described in the section below.

The voltage is read using a 16 bit ADC. The same ADC is shared with infrared distance sensor. The plot axes are fixed.

Settings

The settings page is illustrated below. Note that this settings page is shared with the infrared distance sensor.

Since analog measurements can be noisy, the ADC supports oversampling of the signal. The Oversampling parameter allows the desired oversampling to be selected, from 8X to 1024X oversampling. Higher oversampling will reduce the noise but will add more lag to the measurement. Changing the oversampling will affect the infrared distance sensor as well.

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