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 ...

ACS712 An Arduino library to interact with the ACS712 Hall effect-based linear current sensor. Includes DC and RMS AC current measuring. Supports ACS712-05B, ACS712-10A, ACS712-30A sensors. Typical ...

4-20 mA current output for Arduino Uno The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller. One of the more interesting applications of this ...
