Now, the ESP8266 v7 and v12, include an ADC (Analog digital converter) pin. This means that the ESP8266 module can process inputs from analog sensors. Light sensors, rheostats, force sensors, etc. This is loosely comparable to an Arduino 'Analog IN' pin. With an ADC capability, instead...
Steps to make ESP8266 NodeMCU analog read on dial gauge Step 1: Write a ESP NodeMCU code as given below This code creates a web server on ESP and connects to the given wifi network configuration. Make changes in WiFi Configuration as per your wifi network Code is divided in multiple parts...
the multiplexer selector was verified by connecting each input to ground and verifying the Analog count returned was 0. Likewise, each input was connected to 3.3V with a reading of 1024 returned when reading the ESP8266 ADC pin.

for esp8266 if you want specify SDA e SCL pin use this: PCF8591(uint8_taddress,uint8_tsda,uint8_tscl); then IC as you can see in the image have 4 analog input and 1 analog output: So to read all analog input in one trasmission you can do (the value is from 0 to 255): ...

The ESP8266 ADC pin input voltage range is 0 to 1V if you’re using the bare chip. However, most ESP8266 development boards come with an internal voltage divider, so the input range is 0 to 3.3V. So, in sumary: ADC Voltage range in ESP8266 development boards: 0 to 3.3V (for exam...
