Short circuit protection
The ACS712 Current Sensing module allows for the measurements of both AC and DC currents by a 5V system. The module isolates the reading digital system from the sensed current using an internal hall effect sensor. This module is a 20A version.
The INA169 measures the current on a line by amplifying the voltage drop across a shunt resistor (RS). Using another resistor between the INA169's output and ground (RL) allows for a readable analog voltage output that can be used to measure current. The values and ratio of RS and RL can be changed to cover different current ranges.
