Please run make menuconfig to and enable itĬonst char * myWriteAPIKey = "9U3QMIMX97S6QCUE" Hello there i was hoping someone could advise me on if there is coding in Arduino to measure car 12 volt battery which can reach voltage levels of 15.0 or more, so far i have connected a voltage detection module to an esp32wifi on the 5 volt pin and the reading i am getting at the serial monitor is 5.24. #if !defined(CONFIG_BT_ENABLED) || !defined(CONFIG_BLUEDROID_ENABLED) Hello everyone please can you take a look at this coding which is reading two 12 volt car batteries as the end readings showing on the serial monitor are not as accurate as the voltage reading i am getting from my voltmeter, thanks Voltage Divider Calculator <<< Use 10K for R2, 3.3V for the output V's.

TimePastKalman = esp_timer_get_time() // time of update complete With this app you can monitor the battery status of all your devices. These battery monitors calculate the state of charge of a battery and keep track of the ampere hours consumed from the battery by integrating. XSemaphoreGive( sema_CalculatedVoltage ) The BMV-700H and the BMV-710H Smart are high precision battery monitors that have been specially designed for systems with a high battery voltage ranging from 60 to 385 Volts. Alarm levels can be set so that the unit. XSemaphoreTake( sema_CalculatedVoltage, portMAX_DELAY ) The RF Battery Monitor measures battery voltage of up to 16 remote batteries and displays it on a remote colour screen.

I use the following code to read 12V battery V's with a ESP32.
