Hiletgo analog current meter sensor module ac 0 5a ammeter sensor board based on ta12 100 for arduino.
Arduino high ac current sensor.
Acs712 is a current sensor that can operate on both ac and dc.
Being an ac measurement to do it with arduino we have to create a virtual ground by a voltage divider because we can measure only positive values so that the intermediate value is 2 5v.
The openenergymonitor website has a real nice article about this sensor.
Pin out and pin description of the chip is below.
It sensor can measure current in the range of plus minus 5 ampere and output sensitivity is 185mv a.
This tool consists of a series of precision hall sensors with copper lines.
This causes the maximum amplitude of the voltage is 2 5v.
To assign the circuit values we take the european power system 220v and 50hz.

The difference in voltage from the side of the plate is the output of the sensor.
Yhdc sct 013 000 current transformer.
Understanding the way a sensor is working is the main difficulty.
It mean the output voltage which will appear at the output pin of current sensor is 185 mili volt for every ampere passes through hall effect sensor.
Acs712 is a hall effect based linear current sensor it can measure both dc direct current and ac alternating current.
