ZMPT101B Single Phase AC Voltage Sensor Module

ZMPT101B Single Phase AC Voltage Sensor Module

Building an energy meter, WAPDA voltage monitor or smart home power project? The ZMPT101B module lets your Arduino or ESP32 measure single phase AC mains voltage. It uses a voltage transformer to keep your microcontroller isolated from the mains.

Key Features

• Based on the ZMPT101B precision voltage transformer
• Measures single phase AC voltage, suitable for 220–240V household supply
• Onboard op-amp circuit gives an analog output signal
• Onboard potentiometer to adjust the output gain
• Simple pins: VCC, GND, OUT, plus screw terminals for the AC input
• Works with Arduino, ESP8266, ESP32 and other microcontrollers with an analog input

Common Uses

• DIY energy and power meters, combined with a current sensor
• Mains voltage monitoring and low/high voltage alerts
• Voltage stabilizer, UPS and inverter projects
• IoT power monitoring and university FYPs

Safety Note

• This module connects to live mains voltage. Only wire it with the power off, and keep the AC side insulated.
• Suitable for people with experience working with mains electricity.
• Calibrate the readings against a trusted multimeter in your code.

Package Includes

• 1 × ZMPT101B AC Voltage Sensor Module

Available with delivery across Pakistan, including Karachi, Lahore, Islamabad, Rawalpindi, Faisalabad and Peshawar.
