The ZMPT101B Single Phase AC Voltage Sensor Module<\/strong> is a precision solution for measuring AC mains voltage<\/strong> in embedded and IoT applications. It uses a high-accuracy miniature voltage transformer (ZMPT101B)<\/strong> combined with an onboard signal conditioning circuit to provide a safe, isolated, and stable analog output<\/strong>.<\/p>\n

Designed for single-phase AC systems<\/strong>, this module is ideal for monitoring household mains voltage, smart energy meters, power quality analysis, and automation systems. The onboard adjustable potentiometer<\/strong> allows easy calibration for accurate voltage measurement when interfaced with Arduino, ESP32, ESP8266, STM32, and Raspberry Pi (with ADC)<\/strong>.<\/p>\n

Electrical isolation between the high-voltage AC input and the low-voltage output ensures safe operation<\/strong> in real-world power monitoring projects.<\/p>\n
