ACS712 – 20A Current Sensor Module

Description

The 20A/30A Range DC AC Current Sensor Module ACS712 Module is a competent current sensing module that utilizes the ACS712ELC-20A current sensor chip. It is designed to accurately measure direct current (DC) and alternating (AC) electrical currents within 20 amps or 30 amps, depending on the specific module variant.

The module operates with a 5V power supply and includes an onboard power indicator to provide visual feedback on the module’s power status, ensuring easy monitoring. With the ACS712ELC-20A chip, the module can measure both positive and negative currents up to 20 amps or 30 amps, depending on the model. The analog output of the module corresponds to a voltage of 100mV per ampere of current, ensuring precise and reliable current measurements. When no test current flows through the module, the output voltage will be VCC/2, indicating the absence of current.

The ACS712 current sensor module is based on the Hall test principle, utilizing the Hall effect to measure current. Using the module in an environment free from external magnetic field interference is important to ensure accurate and consistent readings.
