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?
Thanks

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.
I’ve built the full stack project for ESP32+DFRobot SEN0257.
