Current Sensor Module ACS712 Module 5A 20A 30ACurrent Sensor Module 5A/20A/30A ACS712

Features:

• Versatile Current Ranges: This ACS712 module offers multiple current range options (5A, 20A, 30A), allowing you to choose the most suitable one for your specific application. Whether it's for small - scale electronic devices or larger electrical systems, it can accurately detect the current.
• Convenient Power Supply: With a 5V pin power supply and an on - board power indicator, it's easy to set up and monitor the power status. You can quickly determine if the module is working properly just by checking the indicator light.
• Unique Output Characteristic: When there is no test current, the output voltage is VCC / 2. This feature provides a clear reference point and simplifies the analysis of the current detection results, making it more user - friendly.
• Compact Design: The PCB board size of 31mm x 13mm makes it highly compact. It can be easily integrated into various projects, especially those with limited space, without taking up too much room.
• Hall - Based Testing Principle: Based on the Hall test principle, this module offers reliable and accurate current detection. It can effectively sense the magnetic field generated by the current, ensuring high - precision measurement in different environments.
