Sometimes its hard to find best voltage sensor you need to measure the AC voltage, or the line frequency or some other parameters. The main difficulty here is that, it is highly desirable to have galvanic isolation in between the AC mains high voltage and microcontroller or processor. Directly measuring the ac voltage through a simple divider can be too dangerous and increase the complexity of the circuit.  Small instrument transformer which is a best option to solve this problem and measure the voltage with isolation, but such voltage transformer are bulky size is not suitable to mount on PCB.

This AC Voltage Sensor is the low cost solution to solve all the above problem. If you want to measure ac volatage and have size limitations, This is best low cost and  high precision Voltage Transducer for PCB Mounting. This module makes it easy to measure AC voltage upto 1000 volts without any noise. its size is slietally smaller than ZMPC101B.
