I'm working on a system with a distance sensor. As the distance increase, the output voltage decrease. ( Fig. 2 Page 5 : http://www.farnell.com/datasheets/1657845.pdf?_ga=1.97138143.1773643066.1472611965)
Is it better to let the ADC "read" the raw voltage or should I amplify it when the output voltage is too low? (and consider the amplification in software)
How is it possible to know the distance when the output is 1v? (Both 2cm and 27cm match with this voltage)
Any idea? Or should I avoid the scenario of a under 10cm distance object?
