Current Sensor Module ACS712 20A Range can sense upto 20A of current flow. Sensing and controlling the current flow is a fundamental requirement in wide variety of applications, which includes over-current protection circuits, battery chargers, switching mode power supplies, digital watt meters, programmable current sources, etc. It consists of a precise, low-offset, linear Hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field in which the Hall IC converts into a proportional voltage. ACS712 Current Sensor Module – 20A is based on ACS712 sensor, which can accurately detect AC or DC current. The maximum AC or DC that can be detected can reach 20A, and the present current signal can be read via analog I / O port of a microcontroller or an Arduino. Features : The low-noise analog signal path Device bandwidth is set via the new FILTER pin 5 µs output rise time in response to step input current Small footprint, low-profile SOIC8 package 2.1 kV RMS minimum isolation voltage from pins 1-4 to pins 5-8 5.0 V, single-supply operation 66 to 185 mV/A output sensitivity Output voltage proportional to AC or DC currents Factory-trimmed for accuracy Extremely stable output offset voltage Nearly zero magnetic hysteresis The ratio metric output from the supply voltage. Specifications: Current sensor chip: ACS712-20A Operating Voltage (V): 4.5V ~ 5.5V DC Measure Current Range: -20 ~ 20A Sensitivity: 100mV/A Bandwidth: 80 KHz Total output error: 1.5% at TA = 25 DegC Length (mm): 32 Width (mm): 13 Height (mm): 14 Weight (gm): 5 Package Includes : 1 x 20A Range Current Sensor Module ACS712 Note: ACS712 is based on the Hall detection principle, please try to avoid the magnetic field, when using it as it may impact the reading accuracy.
