The ACS712 30A Range Current Sensor Module / Hall Sensor device consists of a precise, low-offset, linear Hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field which the Hall IC converts into a proportional voltage.

Sensing and controlling current flow is a fundamental requirement in a wide variety of applications including, over-current protection circuits, battery chargers, switching mode power supplies, digital watt meters, programmable current sources, etc. This ACS721 current module is based on ACS712 sensor, which can accurately detect AC or DC current. The maximum AC or DC that can be detected can reach 30A, and the present current signal can be read via analog I / O port of Arduino. There is also the 5A and 20A version for your choice are available on our portal.

Note: ACS712 is based on the principle of the Hall test, please use this field to avoid an impact!

The focus keyphrase is the phrase that you want your post or page to be found for in search engines. Sometimes, it is a single word, but it usually consists of a few words. That’s why we call it a keyphrase. For example, if you want your blog post to rank for ‘healthy snacks’, then optimize your post for that term. Your focus keyphrase can also be longer. For instance, you could write an article about healthy snacks specifically made for kids and optimize for ‘healthy snacks for kids’. Or a post about healthy snacks to eat after a workout, and optimize for ‘healthy snacks after
