Esp8266 get battery voltage
Tīmeklis2015. gada 2. jūn. · For readvdd33 to work nothing can be connected to the ADC pin, calling Serial.println (readvdd33 ()>>2); would give the exact value as Serial.println … Tīmeklis2024. gada 4. maijs · The only issue with this is that ADC pins expect voltages between 0 and 3.3 volts and our Ion-Li battery voltage range may reach 4.2 volts. 18650 Ion-Li Battery The solution to that is connecting a voltage divider to the battery, so we can divide the volts by 2 and the maximum value will be about 2.1 volts.

Tīmeklis2024. gada 3. jūl. · First, we need to define the LCD Library and specify the pins we are going to use with the Arduino. We assigned analog pin A4 as the analog pin for checking the battery voltage. The values are set in float so we can get the voltage values up to two decimal places. #include const int rs = 12, en = …
TīmeklisThe ESP8266 only has one ADC and can only handle one sensor at a time. For example, on the ESP8266, you can measure the value of an analog pin (A0 on ESP8266) or VCC (see above) but NOT both simultaneously. Using both at the same time will result in incorrect sensor values.
