The simulation often assumes an ideal transformer ratio. However, in practical applications and some advanced simulation models, a potentiometer on the module allows for gain adjustment. In the Proteus environment, calibration is usually handled in the firmware code by multiplying the calculated RMS value by a calibration constant derived from a known reference voltage.

Reduce the simulation time-step in Proteus ( System -> Set Simulation Options ) or lower the sampling frequency in your code. 2. Output Voltage is Flat or Zero

, converting high AC mains voltage into a safe, low-voltage analog signal suitable for ADC processing by microcontrollers. 2. System Architecture zmpt101b proteus library

The module features an onboard LM358 operational amplifier. Because microcontrollers cannot read negative AC voltage voltages, the op-amp applies a DC offset (usually VCC / 2) to shift the AC sine wave completely into the positive voltage range.

Connect the secondary transformer output to the inverting input (Pin 2) through a resistor. Place the POT-HG in the feedback loop between the output (Pin 1) and Pin 2 to control the gain. Setting Up the Proteus Simulation Environment The simulation often assumes an ideal transformer ratio

Connect the analog OUT pin of the ZMPT101B to the A0 analog input pin of the Arduino.
