| Mar 11, 2023 at 22:43 | comment | added | Adam Cherti | Ok I connected GND of ESP32 to Power Supply GND to which PIN2 of Z19C is also connected. Is that correct? I'm still not receiving any data. | |
| Mar 1, 2023 at 1:53 | comment | added | hcheung | It means connect PIN1 of ESP32S(GND) to pin2 of of Z19C(GND), basic 101 electronics. | |
| Mar 1, 2023 at 1:40 | comment | added | Adam Cherti | Do you mean I should power the sensor with esp's GND/VIN? The issue is that the sensor needs 5v and the board only delivers 3.3V if I'm correct | |

| Feb 28, 2023 at 5:20 | comment | added | hcheung | It is unclear how the GND are connected between the boards. It will be better to have a schematic than those pictures. | |
| Feb 28, 2023 at 5:20 | comment | added | 6v6gt | It is too difficult to follow your wiring in those pictures. A schematic diagram would be much better. You have mentioned a 3.3v and a 5v supply. Do these share a common ground? | |
