ACS 756 Current Sensor
This is a breakout board for the fully integrated linear ACS756 current sensor. The sensor gives precise current measurement for both AC and DC signals. Thick copper conductor and signal traces allows for survival of the device up to 5 times overcurrent conditions. The ACS756 outputs an analog voltage output signal that varies linearly with sensed current.
The device consists of a precision, low-offset linear Hall sensor circuit with a copper conduction path located near the die. Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer. A precise, proportional voltage is provided by the low-offset, chopper-stabilized BiCMOS Hall IC, which is programmed for accuracy at the factory.
ACS756 current sensor operates from 5V and outputs analog voltage proportional to current measured on the sensing terminals. You can simple use a microcontroller ADC to read the values.Sensing terminal can even measure current for loads operating at high voltages like 230V AC mains while output sensed voltage is isolated from measuring part.
ACS56 Current Sensor Module - 50A can sense upto 50A 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.
ACS756 Current Sensor Module - 50A is based on ACS756 sensor, which can accurately detect AC or DC current. The maximum AC or DC that can be detected can reach 50A, and the present current signal can be read via analog I / O port of a microcontroller or an Arduino.
