Description:
The ACS712 Current Sensor Module (5A version) is designed to accurately measure both AC and DC currents within a range of -5A to +5A. It is based on the ACS712 sensor, which provides an analog output that is proportional to the detected current. This sensor is widely used in applications like over-current protection circuits, battery chargers, switching mode power supplies, digital watt meters, and programmable current sources. The module features a low-noise analog signal path and provides precise measurements with stability.
