ZMPT101B 2mA AC Voltage sensor Active single phase voltage transformer module

MPT101B 2mA AC Voltage Sensor Module Product Description: The ZMPT101B is a single-phase AC voltage sensor module designed for safe measurement and monitoring of AC voltage using Arduino, ESP32, Raspberry Pi and other microcontroller-based systems. It uses a precision ZMPT101B voltage transformer for electrical isolation and provides an adjustable analog output suitable for ADC measurement. The transformer itself has a specified linear range up to 1000V/10mA, but the commonly sold module should not simply be advertised as a 1000V AC measurement module; many module versions are intended for mains-voltage sensing around 250V AC. Key Features Single-phase AC voltage measurement Electrical isolation between AC input and measurement circuit Adjustable analog output Suitable for Arduino and other microcontroller ADCs On-board LM358 signal-conditioning circuit Compact PCB design Useful for AC voltage and power-monitoring projects Applications: Arduino voltage meter, ESP32 energy monitoring, AC voltage monitoring, power monitoring systems, smart home projects, electrical measurement and protection systems.
