| AC Input (RMS) | Approx. DC Output | |----------------|-------------------| | 0V AC | 2.50V | | 110V AC | 2.50V + 1.25V = 3.75V | | 230V AC | 2.50V + 2.50V = 5.00V (if adjusted) |

In the realm of modern electronics, the interface between high-voltage alternating current (AC) systems and low-voltage direct current (DC) logic circuits is a critical design challenge. Microcontrollers, such as the Arduino or PIC series, operate at low voltages (typically 3.3V or 5V) and are highly susceptible to damage from high-voltage spikes. To safely measure AC voltage, engineers rely on voltage sensors, among which the ZMPT101B stands out as a popular, compact solution. However, testing these sensors with actual mains voltage can be dangerous and cumbersome. This is where the Proteus Design Suite becomes an invaluable tool, allowing engineers to simulate the behavior of the ZMPT101B safely and accurately before physical implementation. zmpt101b proteus
