This DIY current sensor measures up to 15A and displays it on an OLED screen

When working with electronics, voltage is fairly easy to measure, but current often takes a bit more finesse. For this purpose, Utsav Shah decided to create his own current sensor capable of handling up to 15A. The DIY device uses a shunt resistor, a voltage divider, and an LM358 op-amp to produce a voltage that … Continue reading This DIY current sensor measures up to 15A and displays it on an OLED screen
