Specifications

• Sensor type: ZMPT101B AC voltage transformer module
• Output: Analog voltage (centered at VCC/2 for AC waveform sampling)
• Interface: VCC, GND, Analog output (AO)
• Typical use: 0-250VAC measurement range (depends on module configuration and calibration)
• Compatibility: Arduino, ESP32, ESP8266, Raspberry Pi (with ADC), and other microcontrollers

Wiring and Arduino Integration

Connecting the ZMPT101B to an Arduino is straightforward:

• VCC to 5V (or 3.3V if your module supports it)
• GND to Arduino GND
• AO (analog output) to an analog input pin (for example A0)

Example Arduino analog read and conversion tip:

// Read raw ADC value
int raw = analogRead(A0);
// Map raw ADC reading to voltage after calibration
// Vcc and calibration factors depend on your module and circuit
float measuredVoltage = (raw / 1023.0) * Vcc * calibrationFactor;

Note: For safe and accurate mains voltage measurement, perform calibration against a known multimeter and ensure the module is rated for your local mains voltage. Follow safety practices when working with AC mains.

Calibration and Best Practices

• Always calibrate the module using a trusted AC voltmeter to determine the correct conversion factor.
• Use an isolation transformer or proper protective circuit when measuring high voltages to protect your microcontroller and yourself.
• Filter and average several ADC samples to reduce noise and improve measurement stability.
• Keep wiring short and use proper grounding to reduce interference.

Applications

• Smart home voltage monitoring and protection
• Energy monitoring systems and power usage logging
• Industrial and laboratory voltage sensing
• DIY electronics, power supply testing, and educational projects
