Review on πŸ“Š HiLetgo 5pcs Voltage Detection Module: DC 0~25V Voltage Sensor for Arduino - A Comprehensive Review by Troy Robinson

Revainrating 5 out of 5

Now I can see the battery level.

I used a 10kΞ© resistor to read the ADC on the NodeMcu but it wasn't accurate over 3.3 volts. With this voltage module I can even read voltages around 3.3 volts accurately.

Pros
  • tester
Cons
