Sensors & Modules
The ACS712 is a fully integrated, Hall-effect-based linear current sensor module designed for both AC and DC current sensing. Current flowing through the low-resistance internal copper path generates a proportional magnetic field, which the integrated Hall IC converts into a linear analog output voltage centered at VCC/2 (2.5V at 5V supply).
