ACS712 Current Sensor Module

Product Overview:

The ACS712 Current Sensor Module is an analog current sensor that uses Hall Effect technology to measure the current flowing through a conductor. It is designed to provide precise and accurate measurements of both AC and DC currents in the range of 5A, 20A, or 30A. The module outputs a voltage proportional to the measured current, making it easy to interface with microcontrollers and other electronics for real-time current monitoring.

Key Features:

• Power Supply: The module operates on a 5V power supply with an on-board power indicator.
• Output Voltage at Zero Current: When no current flows through the sensor, the output voltage is approximately VCC / 2, making it easy to detect and measure both positive and negative currents.
• Hall Effect Technology: The ACS712 uses Hall Effect sensing for accurate current detection without the need for direct electrical contact with the conductor, ensuring safety and reliability.
• Precision Analog Output: The module provides an analog output voltage that varies with the measured current:
  • 5A Model: Measures currents from -5A to +5A. The analog output corresponds to 185mV/A.
  • 20A Model: Measures currents from -20A to +20A. The analog output corresponds to 100mV/A.
  • 30A Model: Measures currents from -30A to +30A. The analog output corresponds to 66mV/A.

Specifications:

• Sensor Model: ACS712 (Available in 5A, 20A, or 30A versions)
• Board Size: 31mm x 13mm
• Operating Voltage: 5V (with on-board power indicator)
• Output Voltage at 0A: VCC / 2 (midpoint voltage)
• Measurement Accuracy: Output voltage change is proportional to the current flowing through the sensor (mV/A):
  • 5A Version: 185mV per Ampere
  • 20A Version: 100mV per Ampere
  • 30A Version: 66mV per Ampere
• Working Principle: Hall Effect sensor technology for non-contact current measurement.
• Current Measurement Range:
  • 5A Model: -5A to +5A
  • 20A Model: -20A to +20A
  • 30A Model: -30A to +30A

Applications:

• Power Monitoring Systems: Monitor current usage in power supplies and devices.
• Battery Management Systems: Measure and track current in rechargeable battery systems.
• Motor Control Systems: Measure current drawn by motors and other inductive loads.
• Overcurrent Protection: Monitor current for overcurrent protection in circuits.

Important Notes:

• Zero Current Voltage: When no current is passing through the sensor, the output voltage is at VCC / 2, which is the baseline reference.
• Hall Effect Technology: The ACS712 sensor works on the Hall Effect principle, so avoid strong magnetic fields to prevent interference with the measurements.
