Current sensor module

The ACS712 Current Sensor Module provides accurate AC and DC current measurements using Hall Effect technology. Available in 5A, 20A, and 30A versions, it offers precise analog output: 185mV/A (5A), 100mV/A (20A), and 66mV/A (30A). Operating at 5V, the module delivers an output of Vcc/2 with zero current, and features a compact 31mm x 13mm PCB size with an onboard power indicator. Ideal for motor control, power monitoring, and industrial applications, this sensor offers bidirectional current sensing with high reliability. Note: Avoid strong magnetic fields for accurate readings.
