TīmeklisThe Analogue pin on the ESP8266 can easily be accessed especially on the larger ones where the pin is broken out. The ESP7, ESP12E and ESP201 are good examples of this. On some boards it is identified as ADC or TOUT, it is also known as pin 6 or A0. It has 10 bit precision and its voltage range is between 0 and 1 volt. TīmeklisBecause the ESP8266’s operating voltage range is 2.5V to 3.6V, the board includes an LDO voltage regulator to keep the voltage stable at 3.3V. It can reliably provide up to 600 mA, which should be sufficient even when the ESP8266 is drawing its maximum current (80 mA) during RF transmissions. TīmeklisUse analog sensors with the NodeMCU by reading an analog voltage using the NodeMCU and the Adafruit ADS1015 I2C ADC. The NodeMCU is great, but it is sorely lacking in analog inputs. ... and with the default settings the ADS1015 will map voltages from -6.144V to +6.144V to the range -2048 to +2047 (not +2048).
