What is this?
The ACS712 current sensor is based on the Hall effect principle and can accurately measure the intensity of DC or AC current. The voltage measurement module is based on the principle of resistor voltage division, which can reduce the voltage input to the terminal interface by 5 times.

Are there any advantages of the product?
Hall effect current sensors and voltage modules offer high accuracy, fast response and high reliability.

How to use it?
Connect the current to be measured in series with the input terminals of ACS712,please pay attention to the correct direction.

What should I notice?
ACS712 is based on the principle of Hall detection. Please try to avoid the influence of magnetic field when using it.If using a 3.3V system, the voltage measurement module input voltage cannot exceed 3.3Vx5=16.5V.
