   * **Important:** the ESP32's analog pins can only safely read up to ~3.3V. If you power the sensor from 5V, its output range is higher, so be aware the readings will scale differently — and never feed more than 3.3V into a GPIO pin.   * **Important:** the ESP32's analog pins can only safely read up to ~3.3V.
