Working Principle of ACS712 Current Sensor with Arduino The ACS712 sensor operates on the Hall-effect principle. When current flows through the input terminals (IP+ and IP-), it generates a magnetic ...

1. This circuit, based on a PIC microcontroller with a few added components, converts a sensor-based voltage into a 4- to 20-mA current loop. Shown is the circuit as originally drawn on a whiteboard.

Note that the sensor's baud rate is 2400bps. Table: Output Voltage versus Dust Density. To get the output voltage value, the output of the sensor should be transformed by the following linear function ...

The sensor (in SOIC8 package) consists of a precise, low-offset, linear Hall-effect sensor circuit with a copper conduction path located near the surface of the die. Applied current flowing through ...

The sensor is supplied by a regulated 5V or directly by 12V battery and is ASIL B(D) compliant as per ISO 26262. It also supports system-level integration up to ASIL D. Target applications are close ...
