The ACS712 5A Hall Effect Current Sensor Module<\/strong> is designed for precise low-current measurement<\/strong> in AC and DC systems. Built around the Allegro ACS712 Hall-effect IC<\/strong>, this module delivers a high-sensitivity analog output<\/strong>, making it ideal for applications where accurate current detection is critical.<\/p>\n

With a sensitivity of approximately 185 mV\/A<\/strong>, the 5A variant provides better resolution compared to higher-current versions. The output voltage remains centered at VCC\/2 when no current flows<\/strong>, allowing easy bidirectional current measurement. Electrical isolation between the measured current path and control circuitry ensures safe operation<\/strong> in embedded and IoT projects.<\/p>\n

This module is widely used in battery monitoring, power supplies, energy measurement, robotics, and automation systems<\/strong>.<\/p>\n
