A brief overview of Allegro ACS712 current sensor. Part 2 – Interface the sensor with a PIC microcontroller
In the first part of this discussion, the features of ACS712 device were briefly discussed. Now we will use that theory to implement the ACS712 sensor to make a simple DC current meter. The analog output voltage from the sensor is measured through an ADC channel of the PIC16F1847 microcontroller. A voltage to current conversion […]
