The ACS712 is a Hall-effect-based linear current sensor module that allows precise measurement of both DC and AC currents. It’s commonly used in various electronic applications, including robotics, home automation, and power monitoring. Here are the details for the three different variations:

1. ACS712-05B:
• Measures up to ±5A current range.
• Sensitivity: 185mV/A.
• Ideal for low-current applications.
• Suitable for small-scale projects and low-power devices.
2. ACS712-20A:
• Measures up to ±20A current range.
• Sensitivity: 100mV/A.
• Suitable for medium-current applications.
• Commonly used in home automation systems and robotics projects.
3. ACS712-30A:
• Measures up to ±30A current range.
• Sensitivity: 66mV/A.
• Suitable for higher-current applications.
• Useful in scenarios where more substantial current levels are involved.
