Adjusting the Vref and Gain pots don’t change the arduino output when using the ACS723 low currents sensor hookup guide on your website. Meanwhile, I have a multimeter giving me correct output. I believe the sensor is faulty. I bought it last week from your amazon store.
Hi Kevin,
Sorry to hear you are having issues with your Low Current Sensor. Just to make sure it is not a hardware/connection problem, can you please take a few photos of your board and the circuit you have it in and attach them to your reply? Please do your best to make sure they are clear and well-lit.
