The pump requires 12V, the NodeMCU is powered by a 5V micro USB connector. I decided to use a 12V power supply and a readymade 12v to 5v converter. Software. A 12V AC-AC source is required for true-power measurements. A 12V DC source will power the system without allowing voltage, true-power or power factor measurements. What is it? A NodeMCU shield to measure Real Power by sampling Voltage and Current from the mains. Unfortunately the ESP32 NodeMCU can draw up to 300 mA while booting. When the ESP32 starts up, it pulls so much current out of the AA alkaline batteries that the voltage drops entirely to zero, resetting/crashing the ESP32. In summary, I can not power the ESP32 NodeMCU with 2 AA batteries. diymore Official Store has All Kinds of ESP-12 CH340 CP2102 for NodeMcu V3 V2 Wireless module WIFI Internet of Things Development Board Micro USB ESP8266 ESP-12E,Positive Negative Dual Step Up Boost Converter DC 3V~18V to 5V/6V/9V/12V/15V/24V -5V -6V -9V -12V -15V -24V Power Supply Module,AC 80-300V 100A LCD Digital Ammeter Meter Voltmeter Power Module Volt Watt Power Kwh and more On Sale ... 220V to 12V mini power supply; Roll over image to zoom in. 220V to 12V mini power supply ...
