This causes the maximum amplitude of the voltage is 2 5v.
Arduino high ac current sensor.
Hiletgo analog current meter sensor module ac 0 5a ammeter sensor board based on ta12 100 for arduino.
To assign the circuit values we take the european power system 220v and 50hz.
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.
Current transformers cts are sensors that are used for measuring alternating current.
The difference in voltage from the side of the plate is the output of the sensor.
Pin out and pin description of the chip is below.
Understanding the way a sensor is working is the main difficulty.
Acs712 is a current sensor that can operate on both ac and dc.
This tool consists of a series of precision hall sensors with copper lines.
This sensor operates at 5v and produces an analog voltage output proportional to the measured current.
It sensor can measure current in the range of plus minus 5 ampere and output sensitivity is 185mv a.
Similarly for other sensors but sensitivity is different for them.

The openenergymonitor website has a real nice article about this sensor.
Acs712 is a hall effect based linear current sensor it can measure both dc direct current and ac alternating current.
