DT-Sense Current Sensor with OpAmp is current sensor which uses hall effect principle based on AC712. This module can be used to measure the AC or DC current. This module has equipped with OpAmp based on TLC272A to improve the input sensitivity and be able to measure a small current. This module is well suited for motor controller, power monitoring, switch mode power supply sensor, etc.
