### Battery voltage monitoring ### Battery voltage monitoring (optional)
ESP32 ADC can measure only up to 3.3 V, so you need to use a voltage divider to monitor the battery voltage. To enable voltage measurement, set the following parameters: ESP32 ADC can measure only up to 3.3 V, so you need to use a voltage divider to monitor the battery voltage.
