The ZMPT101B is an AC voltage sensor module used to measure mains voltage with microcontrollers such as Arduino, ESP32 and other development boards. It uses a small voltage transformer to provide electrical isolation while producing a low-voltage output signal that can be read by an analogue input.
The module includes an adjustable potentiometer for setting the output sensitivity, making it suitable for projects such as voltage monitoring, energy-monitoring systems, power meters and smart-home applications.
Important: The ZMPT101B is intended for AC voltage measurement and working with mains electricity can be dangerous. Always use proper electrical isolation, insulation and safety precautions.
