The ZMPT101B AC Voltage Sensor Module (commonly called ZMPT sensor) is a compact module used for measuring AC voltage safely with microcontrollers like Arduino, ESP32, or Raspberry Pi.
🔹 Key Features:
Core Sensor: ZMPT101B voltage transformer
Input Voltage Range: Up to ~250V AC (mains level)
Output: Analog voltage proportional to AC input (can be read via ADC pin)
Operating Voltage (module): 5V DC
High Accuracy: Can detect even small AC variations
Isolation: Transformer-based, provides electrical isolation from mains
Onboard Components:
Adjustable potentiometer (to set sensitivity/gain)
Signal conditioning circuit for stable output
🔹 Working Principle:
The ZMPT101B mini transformer steps down the AC mains voltage.
The signal is conditioned and scaled to a safe analog voltage (0–5V).
A microcontroller ADC pin reads this value.
With calibration, you can measure RMS voltage of mains supply (110V / 220V).
🔹 Applications:
AC mains voltage monitoring (110V / 220V).
Smart energy meters.
IoT home automation (real-time voltage data logging).
Over-voltage / under-voltage protection systems.
Industrial monitoring (detecting fluctuations, drops, surges).
⚠️ Safety Notes:
Although the module provides isolation, it is still connected to live AC mains → handle with care.
Always insulate connections properly and avoid touching when powered.
Use fuses for extra protection.
