The ACS712 30A Current Sensor Module features a precise, low-offset linear Hall circuit with a copper conduction path situated near the surface of the die. When current flows through this path, it generates a magnetic field that the Hall IC converts into a proportional voltage.
Monitoring and controlling current flow is essential for a wide range of applications, including over-current protection circuits, battery chargers, switching power supplies, digital watt meters, and programmable current sources.
This ACS712 current module is designed to accurately detect both AC and DC currents, with a maximum detection capability of 30A. The current signal can be easily read through the analog I/O port of an Arduino.
Note:
ACS712 is based on the principle of the Hall test, please use this field to avoid an impact!
Features
Low-noise analog signal path
Device bandwidth is set via the new FILTER pin
5 µs output rise time in response to step input current
Small footprint, low-profile SOIC8 package
2.1 kV RMS minimum isolation voltage from pins 1-4 to pins 5-8
The 30A Range Current Sensor Module ACS712 is a versatile current and voltage sensor used across a wide range of applications including power monitoring, energy metering, battery management, solar panel monitoring, and industrial current sensing.
Common use cases:
Monitoring power consumption of appliances
Building a solar panel efficiency tracker
Current sensing in a battery management system
This product is ideal for power electronics engineers and IoT developers.
Technical Tip: Hall-effect sensors are non-invasive (no wire cutting needed). Shunt-based sensors offer higher accuracy. Match the sensor range to your application.
