The ZMPT101B is a voltage
transformer used to measure AC voltage. You can measure AC voltages up to 250
volts by using this module. The output of this sensor is analog. if you change
input voltage, the output voltage will change as well.
Note
When there is no load on output
(nothing is connected to infput), the sensor has an initial voltage (Offset) of
VCC/2. That is, if nothing is connected to the input and the supply voltage of
the module is 5 volts, the output of the module will be 2.5 volts.
