ACS712 Hall Current Sensor Module
Measure AC or DC current up to 30A with this range of ACS712 Hall Current Sensor Modules from PMD Way.
Select your required maximum current using the options menu.
These sensors are very simple to use. Connect the terminal blocks in series with the load you're measuring. Connect 5V DC to the VCC and GND pins.
The OUT pin will present a DC voltage that you're development board's analog input can measure. This signal will be proportional to the amount of current being measured:
- 5A module will output 185mV per A measured
- 20A module will output 100mV per A measured
- 30A module will output 66mV per A measured
