AC Voltage Sensor Module (ZMPT101B)

The ZMPT101B AC Voltage Sensor Module is a high-precision voltage sensor used for monitoring AC voltage in power systems. It uses a ZMPT101B precision voltage transformer to isolate and step down the AC voltage signal, making it safe to interface with microcontrollers.

The module includes an operational amplifier circuit and a multi-turn potentiometer for sensitivity adjustment, allowing accurate voltage measurement. This sensor is commonly used in energy monitoring systems, smart meters, voltage monitoring devices, and IoT-based power management projects.
