current sensor ACS712

Current sensor ACS712

The current sensor ACS712 is a device that measures the amount of current flowing through a circuit. It works based on the Hall effect, which makes it easy to measure and interpret the current. The ACS712 is available in various versions with different current ratings and can be used in both AC and DC circuits.

The current sensor is easy to use and can be connected to a microcontroller or other electronics to monitor the current in real-time. It is compatible with a wide range of microcontrollers, making it ideal for use in various projects, such as current monitoring systems, power metering systems, and motor control systems.

With the help of the ACS712, you can detect overcurrent or undercurrent conditions, which can help prevent damage to your circuits and equipment. Whether you’re a hobbyist or a professional, the current sensor ACS712 is an excellent choice for anyone who needs to measure the current accurately and efficiently.

The Allegro^??ACS712 provides economical and precise solutions for AC or DC current sensing in industrial, commercial, and communications systems.These are good sensors for metering and measuring overall power consumption of systems. The ACS712 current sensor measures up to 5A of DC or AC current.

The ACS712 Low Current Sensor Breakout outputs an analog voltage that varies linearly with sensed current. To calibrate, first set the output offset to the desired level (with zero current on the sense lines, read output with a DVM). Then with a known current input (a 100mA limited supply works well for this), set the output deflection with the gain pot. Sensitivity is then calculated as (Vref ? Vdeflect)/(current input).
