<![CDATA[pH analog sensor and Core2]]>Hi,

I've bought this sensor https://botland.store/gravity-temperature-sensors/15094-gravity-ph-analog-sensormeter-v2-dfrobot-sen0161-v2-6959420914234.html which unfortuanally doesn't work well with ESP32 analog input.

Is there any workaround? Maybe some external analog input or a module from M5Stack that I can connect?

I can confirm it because analogRead() returns some unreal value of voltage: 8461.9
