Módulo sensor de corrente ACS712T ELC-05B intervalo 5A

Wired it into my bench supply to monitor a motor draw, and the VCC/2 zero point was dead-on right out of the box. The 5A range feels solid for small projects, and the power LED is a nice touch when I forget which way the pins go. Took maybe ten minutes to get a clean reading on my multimeter.

The 185mV/A sensitivity makes calibration surprisingly straightforward, and the VCC/2 zero point means I barely had to tweak my offset in code. The power LED is bright enough to confirm it's live even in a messy breadboard setup, and negative current readings came through clean.

I connected this to my Arduino and the 185mV/A sensitivity made reading current changes super clear on the serial monitor. The onboard LED helped me quickly verify it was powered before starting my project.
