ACS712 30A 30 Amp Current Sensor Module
The ACS712 Module uses the famous ACS712 IC to measure current using the Hall Effect principle. The module gets its name from the IC (ACS712) used in the module, so for you final products use the IC directly instead of the module.

How to use the ACS712 Module
As told earlier it is very simple to interface the ACS712 Module with Microcontrollers. The below diagram would be more illustrative
The ACS712 module has two phoenix terminal connectors (green colour ones) with mounting screws as shown above. These are the terminals through which the wire has to be passed. In our case I am measuring the current drawn by the motor so the wires that is going to the load (motor) is passed through the ACS 712 Module. Make sure the module is connected in series with the load and be extra cautious to avoid shorts.
On the other side we have three pins. The Vcc is connected to +5V to power the module and the ground is connected to the ground of the MCU (system). Then the analog voltage given out by the ACS712 module is read using any analog pin on the Microcontroller.
Pin Configuration
| Pin Number | Pin Name | Description |
| 1 | Vcc | Input voltage is +5V for typical applications |
| 2 | Output | Outputs Analog voltage proportional to current |
| 3 | Ground | Connected to ground of circuit |
| T1 | Wire In | The wire through current has to be measured is connected here
|
| T2 | Wire Out |
Useful Link
- Measures both AC and DC current
- Available as 5A, 20A and 30A module
- Provides isolation from the load
- Easy to integrate with MCU, since it outputs analog voltage
- Scale Factor
| 5A Module | 20A Module | 30A Module |
| 185mV/Amp | 100mV/Amp | 66mV per Amp |
