External power supply to ESP32 and NodeMCU
You may want to see if your sensors have 3.3V regulators on them, the ESP32 is NOT 5V tolerant. To be sure that the project works I would create 5 volt for the sensors using a buck converter. Any 5 volt controller can use the same +5 volt. Never use Vin and tap more than a few mA from controller 5, or 3.3 volt converter.
Power Supply for ESP32 with Boost Converter & Battery Charger …
Earlier we designed Power Supply for NodeMCU, we will redesign the same circuit here for ESP32. Most of the Lithium-Ion/Lithium Polymer Batteries can only fully charge up to 4.2V which is not enough for ESP32 Board. So we need to step-up the 2.8V-3.7V voltage from Battery to 5V. That is the reason why we are using a small-sized Boost …
Using 5v 3A to power nodeMCU?
I am not sure what "old computer" uses a 5 V 3 A power supply, for most PCs it would be nearer 30 A. However as long as it is a properly regulated 5 V, it will be just fine.
