ACS712 Current Sensor Module
You can use this module directly with Arduino to measure current and power of a load.
You can use this module directly with Arduino to measure current and power of a load, typically a lamp, heater or power distribution of an electrical system.
This module utilizes ACS712 Hall-effect based linear current sensor to measure current using the Hall Effect principle.
ACS712 current sensor can measure current AC or DC current ranging from +5A to -5A, +20A to -20A and +30A to -30A. You have to select the right range for your project since you have to trade off accuracy for higher range modules. This modules outputs Analog voltage (0-5V) based on the current flowing through the wire; hence it is very easy to interface this module with any microcontroller. So if you are looking for a module to measure current using a microcontroller for you project then this module might be the right choice for you.
Note : When there is no current pass through this module, the output voltage would be at a center voltage of 2.5V.
