Hi, Using an esp32c6 and esp-idf version 5.1.1 I've set up a voltage divider with two 100k resistors to measure battery voltage. When I use adc1ch1 (gpio1) it pulls the voltage of the divider down throwing the measurement off. If I use adc1ch2 (gpio2) it does not. Is this so...
You can use one of the ADC channels available on the ESP32-S3 to measure the voltage. Connect the input voltage (3.3V in your case) to one of the ADC pins, and then use the ADC API to read the voltage. 2 posts • Page1of1 ...
If necessary, you can consider connecting the positive and negative terminals of the battery to two of the pins to measure the battery voltage.caution When you use battery power, there will be no voltage on the 5V pin. At the same time, we designed a red indicator light for battery ...
Theconstant current loadThe charging process lasts almost the entire charging process. This means thatthe charger will keep changing the voltagesupplying the battery as required, so that the battery always absorbsthe same intensity. When the charger detects that the battery is close to 4.2 volts, ...
Unfortunately my project cannot sleep so long. Im measuring temp,humidity and air quality. Those sensors require some time to measure. Also, i need the values at least once per 2 minutes. Somebody mentioned a back feeding the ldo. I've ordered a bare ESP32-WROOM module and gonna use bett...
Can the battery voltage be measured through the device? Yes you can measure battery voltage using gpio35 Why is it impossible to find which mcu is on this board? Esp32-? Sold by lilygo Official Store(Trader) Ship to Vietnam AliExpress commitment ...
coprocessor in ESP32 is also designed to measure voltage, while operating in the sleep mode, which enables low-power consumption. The CPU can be woken up by a threshold setting and/or via other triggers. With appropriate settings, the ADCs can be configured to measure voltage on 18 pins ma...
My BLDC motor stops slowly when switching and now I just have to manage to measure the battery capacity and remaining battery. If you have any tips on reading the battery, I would be happy if you could help me. Thank you again. Like 190 0 ...
