Description
xPart Overview
The JESSINIE 5-piece ZMPT101B Voltage Transformer Module is a precision single-phase AC voltage sensing module commonly used in DIY energy monitoring, Arduino / Raspberry Pi power-meter projects, motor protection circuits, and workshop instrumentation. Each module steps down mains AC to a safe, low-voltage analog signal (typically 0-5V) suitable for an ADC or microcontroller input. With five identical boards in the pack, you can prototype, build a multi-channel monitor, or keep spares on the bench. Backed by our 1-year warranty and free worldwide shipping.
Compatibility & Typical Use
| Platform / Project | Typical Application | Interface | Notes |
|---|---|---|---|
| Arduino (Uno / Mega / Nano) | DIY AC voltmeter, energy monitor | Analog input (0-5V) | Pair with ZMPT101B-compatible sketch libraries |
| Raspberry Pi (with ADC) | Mains voltage / power logger | External ADC input | Use with ADS1115 or similar 16-bit ADC |
| Industrial monitoring | Single-phase voltage sensing, motor protection | 0-5V analog output | Verify isolation and calibration for field use |
