Current Sensor Amplifier & Over Current Switch

https://www.electronics-lab.com/project/current-sensor-amplifier-current-switch/

This current sensor amplifier and over current switch project is based on ACS714-30A current sensor and LM358 OPAMP, ½ of LM358 op-amp used as an amplifier for low voltage  and 2nd 1/2 LM358 op-amp used as a comparator which provides over current TTL output, trimmer potentiometer provided to set the over current limit.  ACS714 sensor […]
