Esp32 Negative Voltage. discover how to measure voltage with an esp32, use a voltage sensor, and program your esp32 step by step. i would like to get 3.3v on the gpio input pin when the switch is open, and 0v when the switch is closed. i aim to utilize my esp32 to capture an analogue signal, which may contain both positive and negative values. The positive gets connected to and adc1 pin. the ads can measure negative voltages, if you connect 'ground' of your voltage divider to a known voltage, like 3.3volt. We provide detailed instructions, codes, wiring. for slow 5v signals, it should be possible (though hacky) to use a single high value series resistor (1k or, ideally,. you need to connect the negative from the voltage divider to gdn of esp32. hi, i'm going to use a non invasive current sensor and my main concern right now is if negative voltages in the analog pin can.
