Description
Current sensor operating in the range from 10 mA to 5 A on the basis of Hall effect. The output is an analog voltage. The supply voltage is 5 V. It has a built-in amplifier and potentiometer for adjusting the sensitivity.
The module can measure direct current and alternating current in the range of up to 5 A, and its basic sensitivity is 400 mV / A. Default sampling rate is 20 kHz. Built-in amplifier is able to achieve 2.2 to 22 V / V.
Pins
The module has the following pins:
| Pin | Description |
|---|---|
| VCC | The supply voltage of 5 V. |
| VOUT |
The output voltage proportional to the current IP+ and IP-. |
| GND | The ground of the system. |
| IP + | The input of the current sensor. |
| IP - | The input of the current sensor. |
