MECCANIXITY 3pcs ACS712 Current Sensor Module 20A Range Hall Effect Current Sensor Current Measuring AC/DC for Detecting Current

What is this?The ACS712 current sensor module is a Hall effect current sensor integrated circuit (IC) used to measure the intensity of DC or AC current. Current measurement sensor accurately detect the current intensity passing through the wire and are widely used in current detection, motor control, power management, smart home, industrial automation and green energy.What will I get?Current sensor chip: ACS712ELC-20A;Pin 5V power supply, on-board power indicator;Measuring range: ±20A, corresponding to analog output 100mV/A; When no detection current passes, the output voltage is VCC/2; Size: 31.5mmx13mm/1.24x0.51 inch(L*W); Terminal pin pitch: 2.54mm; Package Included: 3pcs x Current Sensor ModuleAre there any advantages of the product?Hall effect current sensors have the characteristics of high accuracy and low drift, and can accurately measure the intensity of DC or AC current. They have fast response speed, high reliability and wide application range.How to use it?Connect the current to be measured in series with the input terminals of ACS712,please pay attention to the correct direction.What should I notice?ACS712 is based on the principle of Hall detection. Please try to avoid the influence of magnetic field when using it.
