  • Hello Dir Support Team

    I have the 5A version of ACS712, and i would like to measure 50mA from a LED stripe, using Energymicro STK 3700. after making all connection the GND Pin and the VCC pin of the ACS712 are signaling a contact that mean something is wrong with my circuit. As I am a begginner,could someone please tell me how i could design my circuit to avoid this problem ? First I used a 12V power supply for the LED, and a 5V power supply for the ACS712 separately, but the output voltage was stilled 0V. Then when i connect my circuit so that the GND of 12V supplier and the GND of the 5V are connected it work but after a few days the ACS712 sensor signals a contact between his GND PIN and his VCC PIN and becomes heater that means something is wrong. could someone please have an circuit example how it could work with a 12V LED and the 5V power supply.

    Thanks in advance !!!
