Dreams Link - acs712 hocheffizienter hall-stromsensormodul-detektor dc5v für arduino (20a)

Specification: origin: mainland china type: module condition: new current sensor chip: acs712elctr-05b-t on-board power indicator operating voltage: dc5v single voltage operation accuracy range (ip): can measure ± 5a current, corresponding to the analog output 185mv / a; ip = 0a i.

, when there is no detectable current passing through, the output voltage is vcc/2 i.

calculation formula: vout=2.

185*ip range: 5/20/30/40/50a product size: 32.

00mm/1.

47inch this module is a linear current sensor, designed based on the principle of hall sensing, built-in precise low bias linear hall sensor circuit with a copper foil located close to the surface of the ic.

when the current passes through the copper foil, a magnetic field is generated, and the hall element senses a linear voltage signal according to the magnetic field, which is amplified, filtered, chopped and corrected by the internal circuit.

after internal amplification, filtering, chopping and correction circuit, the output voltage is proportional to the detected ac or dc current.

it can be applied in motor field, load detection and management, switching power supply and over-current fault protection.

note: acs712 is based on the principle of hall detection, try to avoid the magnetic field caused by the use of this effect.

due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.

thank you! please allow 1-2cm measuring deviation due to manual measurement.
