Needs Calibration
Works well overall, but you definitely need to calibrate it against a multimeter before relying on the readings. Once tuned, it is quite accurate for hobbyist projects.

Compact and Reliable
Perfect size for my ESP32 setup. The pins are standard spacing which made wiring simple. No issues with noise on the output signal so far.

Great for Home Energy Monitor
Used this module for my DIY energy monitoring project. The output is stable and the isolation gives me peace of mind when working with mains voltage. Calibration was straightforward using the potentiometer.

Accurate Readings
I compared this against a professional meter and the readings were very close after adjustment. The form factor is small enough to fit inside my enclosure easily.

Good Value
For the price, this is a solid voltage sensor. Just remember this is for AC voltage only, not DC. Documentation could be better, but there are plenty of examples online.
Q: Do I need to install any specific libraries to use this?
A: No specific library is required. You can read the analog output pin using standard analogRead functions in your IDE and calculate voltage via code.
Q: What is the maximum input voltage this module can handle?
A: The module is designed for an AC input range of 0-250V. Please do not exceed this rating to ensure safety and module longevity.
Q: What is the output voltage range sent to the microcontroller?
A: The output is scaled to an analog DC signal ranging from 0 to 5V, which is compatible with most standard ADC inputs on Arduino and ESP boards.
Q: Is there electrical isolation between the high voltage and the logic side?
A: Yes, the module uses an electromagnetic isolation transformer to separate the high voltage AC input from the low voltage output side.
Q: Can this sensor measure DC voltage?
A: No, the ZMPT101B is specifically designed for Single-Phase AC voltage measurement only. It will not provide accurate readings for DC sources.
