The ZMPT101B AC Voltage Transformer Sensor Module is an isolated voltage-sensing module designed for measuring AC voltage in electronic monitoring and control systems. It uses a miniature voltage transformer to provide electrical isolation between the measured AC circuit and the low-voltage measurement circuitry.
The module provides an analog output that can be connected to a suitable Arduino, ESP32, STM32, Raspberry Pi ADC, or other microcontroller-based system for AC voltage monitoring and measurement. An onboard adjustment potentiometer can be used to configure the signal level for the connected measurement system.
