  • Battery voltage reading via ADC

    Oct 26, 2017· Battery voltage reading via ADC Post by mustafacc » Tue Sep 05, 2017 2:37 am I'm seeing an interesting behavior from the ESP32 ADC when I'm trying to measure the ESP32's power supply's voltage (LiPo battery)...

  • Battery voltage monitor with nodemcu Esp8266

    Sep 29, 2019· During charging battery voltage can increase to 18 volts For example150 watt solar panel outputs 17 volts at 6 amperes during full sun, output voltage can even reach above 18 volts Solar charge controller also output voltage approximately equal to 15 volts to charge the batteri...

  • 37V Lithium battery as power supply for the DOIT ,

    May 03, 2018· I've tried putting the 37V on Vcc - failed Putting it on the USB port fails too I even used an external low voltage-drop regulator (04V at 400mA) and put it on 3V3 - failed Last and final test was putting the regulated 33V onto Pin 2 (Vout) of the onboard voltage regulator - failed...

  • WIFI Battery Monitor System

    WIFI Battery Monitor System - ESP8266: One of the main problem in battery powered projects is to choose/use the proper battery size/model/type As market is flooded now with a lot of low quality batteries claiming thousands of mAh ( Ultrafire fakes stories is just an example) the ....

  • ESP8266 Thing Hookup Guide

    If both USB and LiPo are connected to the Thing, it'll take power from the USB port and charge the LiPo battery at up to 500mA Electrical Characteristics The ESP8266's maximum voltage is 36V, so the Thing has an onboard 33V regulator to deliver a safe, consistent voltage to the IC...

  • Reading Battery Voltage internally

    Jan 16, 2017· Re: Reading Battery Voltage internally Post by deshipu » Mon Jan 16, 2017 2:11 pm The ESP8266 hardware can do it, however, this has to be enabled at the time of compiling the firmware/flashing, and MicroPython doesn't have support for it...

  • Electrostatic precipitator

    Power suppli You have a lot of power supply options here! We bring out the BAT pin, which is tied to the lipoly JST connector, as well as USB which is the +5V from USB if connectedWe also have the 3V pin which has the output from the 33V regulator We use a 500mA peak low-dropout regulator Please budget 250mA for the WROOM32 module...

  • Electrostatic Precipitator

    Conceptual drawings of (a) a single-stage electrostatic precipitator (ESP) and (b) a two-stage ESP In ESPs, field charging is the predominant mechanism for charging particles with diameters larger than 1 µm, whereas diffusion charging is predominant for particles smaller than 100 nm ( Hinds, 1999 )...

  • Check Battery Level

    - Thu Mar 16, 2017 4:01 pm #63789 Hello i have an ESP8266 with NodeMCU 096 build 20150704, is connected to a li-po 37V and 500mAh, in the VCC and the GND, i want to know if there is a way to read the battery level from LUA and turn on a led if is low the battery, or i need some special hardware configuration, thanks for your help...
