AC Current Sensor ZMCT103C High Precision Current Transformer Single-Phase 5A/5mA Power Sensor Module Electronic DIY For Arduino
AC Current Sensor With OP Amp
Introduction:
The module is equipped with the ZMCT103C series of small high-precision current transformers and high-precision op amp circuits for accurate sampling and proper compensation of signals. It is convenient for signal acquisition of AC power within 5A. The corresponding output analog AC signal can be adjusted. The required output voltage can be adjusted according to the potentiometer (adjusting the amplification ratio, the amplification range is 0-100 times), but the maximum voltage at the output (OUT) will not exceed 1/2 VCC.
