Hi , I have interfaced ESP32 with acs712 current sensor but I am not getting proper values for current sensed. I have followed the interfacing ardino uno with acs712. Has anybody done it succesfully.Please attach the circuit daigram between esp32 and acs712 with code for programming ,Any code will do i.e ardino ide / rtos.

Keep in mind that the asc712 works on 5V and the Esp32 on 3.3V
So if you feeding the sensor with 5V you have to reduce the output to the 3.3V scale with a voltage divider.
What current are you measuring AC, DC?

If you want to measure energy consumption please have a look at my blog for the Pzem-016.

Thanks ,
I am measuring AC , also this is for energy consumption of devices. Please provide working circuits for interfacing ACS712 20A module and ESP32.
