The ACS712 Current Sensor Module is a fully integrated linear current sensor that uses its conductor to calculate and measure the current applied in the circuit. It uses indirect sensing in which the integrated hall effect sensor detects the incoming AC or DC current through its magnetic field generation and then generates a voltage proportional to measure the current. It is used in a wide range of applications since it is applicable to detect AC and DC current, such as motor speed control, electrical load detection and power supplies.
- Supply Voltage: 4.5V~5.5V DC
- Measure Current Range: -5A~ 5A
- Sensitivity: 180mV/A ~190mV/A, Typical: 185mV/A
