ACS712 5A Range Current Sensor Module

Sensing and controlling current flow is a fundamental requirement in a wide variety of applications including, over-current protection circuits, battery chargers, switching mode power supplies, digital watt meters, programmable current sources, etc. This ACS721 current module is based on ACS712 sensor, which can accurately detect AC or DC current. The maximum AC or DC that can be detected can reach 5A ACS712ELC-05B sensor chipset Powered by 5V power supply On-board power indicator Measures -5~+5A current, corresponding simulation output 185mV/A Output voltage is VCC/2 when on current was measured ACS712 is based on the principle of Hall detection, please avoid the magnetic field affect when using it
