Gravity 3wire sensor to ESP32?

So im trying to read the data from this, I believe, analog sensor.

Is this possible to do on a ESP32 without anything else required.

Do I need some kind of ADC to convert it?


There is ADC pins on an ESP.
But it can go as high as 4.5 volts, so you need to get that down to below 3.2 volts. Either with a level shifter or a voltage divider.
