Current Sensor Module; Model : ACS712, Range Current : 30A, Current sensor chip: ACS712ELC-30A. The module can measure positive and negative 30A current, corresponding to analog output 66mV/A; IP=0A, that is, when there is no detection current passing, the output voltage is VCC/2. ACS712 is based on the principle of Hall detection, try to avoid the influence of magnetic field when using it. load detection and management in the field of electric motors, and overcurrent fault protection in the field of switching power supplies and various electronic products. You will get 5 x ACS712 30A Range Current Sensor Module, 1 x 15Pin Female to Male Dupont Cable.
