AC Voltage Sensor - ZMPT101B

AC Voltage Sensor - ZMPT101B The ZMPT101B AC Voltage Sensor is a high-precision module designed to measure household AC voltage safely and accurately. It utilizes an onboard micro-precision voltage transformer to isolate the high-voltage input, providing a safe analog output that can be easily read by microcontrollers like Arduino or ESP32. Key Features: Galvanic Isolation: High-quality transformer provides physical separation between AC mains and your low-voltage electronics. Precise Measurement: Capable of measuring AC voltages up to 250V with high linearity and consistency. Adjustable Output: Includes an onboard multi-turn potentiometer to calibrate the output signal level for your specific MCU. Compact Design: Small footprint makes it easy to embed into smart energy meters and power monitoring systems.
