5A Single-Phase AC Current Sensor

Precision Current Transformer Core: Built with an onboard ZMPT/HWCT-style micro precision current transformer to convert 0 - 5A AC input currents into a low-level signal.

Onboard Signal Amplification Circuitry: Features an integrated operational amplifier that scales and conditions the transformer output into a smooth analog voltage.

Onboard Sensitivity Trimmer Potentiometer: Equipped with a multi-turn trimmer to easily adjust output signal gain and match your microcontroller ADC voltage sampling range.

Galvanic Line Isolation: Safely samples high-voltage AC current lines without direct electrical contact with sensitive host microcontrollers.

Compact Breakout Form Factor: Built on a compact PCB with standard 0.1'' (2.54 mm) header pins for easy integration into breadboards and custom control enclosures.

Housing & Board Material: High-grade FR-4 glass-epoxy PCB with a black plastic-encapsulated current transformer, blue potentiometer, and tinned header pins.

Technical Specifications:

Operating Supply Voltage (V_CC): 5.0V DC (Op-Amp Power).

Target Input Current Range: 0A - 5A AC (50Hz / 60Hz).

Output Signal Type: Analog Voltage Waveform.

Color: Blue PCB with Black Transformer Module and Silver Pins.

Usage Advice: Pass the target AC live wire through the center aperture hole of the transformer coil; connect VCC (5V) and GND, and route the OUT pin to an analog pin on your Arduino, ESP32, or Raspberry Pi.

Maintenance: Ensure the target conductor passes cleanly through the center aperture; keep the board dry, clean, and free from static discharge.

Essential Appliance Load Sampling Sensor: Position as an indispensable AC current sensor for home energy monitors, smart plug power loggers, pump current monitoring, and appliance diagnostic systems.

Highlight Non-Invasive Transformer Isolation: Emphasize how non-contact magnetic sampling provides complete electrical isolation between AC mains wiring and low-voltage microcontrollers.

Recommended Cross-Sell Add-ons: Pair with (Analog) AC Current Transformer, HWCT5A/5mA Micro Current Transformer, AC Single Phase Voltage Transformer Sensor, and ESD antistatic mat 50x40CM PCB Welding Mat.
