Member Function Documentation

read()

virtual float sensesp::BaseAnalogReader::read ( )

pure virtual

Read the input as a fraction of the full-scale reference voltage.

Returns

A value in the range 0..1, where 1.0 corresponds to the reader's full-scale reference voltage. Normalizing here keeps AnalogInput independent of the ADC bit width, which varies between ESP32 variants.

Implemented in sensesp::ESP32AnalogReader.
