The module (Sensor 5A + Current) is a current sensor module based on ACS712ELCTR-05B. Based on the Holzer principle, the current is converted into analog voltage output, MCU (UNO R3 AD) with Arduino converter can read out the voltage value and transform into the measured current value, which is suitable for the 5V power supply system. Can measure AC and DC power, the range is + 5A. Widely used in current monitoring and other occasions.
Module features are as follows:
1 the power supply voltage is 4.5~5.5V;
TwoStandard electronic building block interface;
3 range is + 5A;
4 sensitivity of the typical value is185MV/A;
5 the output voltage of the test current is zero when the output voltage is half of the supply voltage (VCC/2);
6 at the bottom thereProtection boardTo avoid short circuit and electric shock;
7 to measure the current interface of the current interface wiring and add heat sink, enhance the capacity of carrying capacity;
8.4 M2 screw positioning holes, easy to install;
Note: avoid the impact of strong magnetic fields around!

The interface of the ACS712 current sensor module is shown in the following figure:
control interfaceStandard electronic building block interface, a total of 3 pins (GND, VCC, VOUT), GND for the ground, VCC for the power supply, VOUT analog voltage output.
Test current interface: in general, IP+ connected to the current flow of the line, IP- the current outflow of the line, that is, from the IP+ flow into the chip from the IP- outflow. Of course, this is not mandatory, in turn,
