Introduction:
This module is based on the ACS712 current sensor module. The current is converted to an analog voltage output based on the Hall principle, and the instantaneous value is output. The MCU with an AD converter (Arduino UNO R3) reads the voltage value and converts it to a measured current value for a 5V powered microcontroller system. Can measure AC, DC, range is ± 30A. Widely used in overcurrent detection, current monitoring and other occasions.

Features:

- Operating voltage VCC: 4.5 - 5.5VDC;

- Standard electronic building block interface;

- Range: ± 30A;

- Sensitivity: 66mV / A (typical);

- Measurement error: ± 2%

- Test interface: high-quality high-current terminals, easy wiring, measurement safety

- The output voltage is half of the supply voltage (VCC / 2) when the current to be measured is zero;

- Current interface to be tested is PCB double-sided wiring and add a large number of cooling holes, the bottom of a layer of tin welding, enhanced current carrying capacity, you can continue to power 30A current;

- Note: Please avoid the influence of strong magnetic field around when using! You usually need to do zeroing before measuring.
