Current Sensor 20A (ACS712-20A) เซนเซอร์วัดกระแส 20 แอมป์

แรงดันไฟฟ้า: 4.5 ถึง 5.5 โวล์

ช่วงการวัด: -20 ถึง 20A

ความไว: 180mV/A ~ 190mV/A, Typical: 185mV/A

Sensing and controlling current flow is a fundamental requirement in a wide variety of applications including, over-current protection circuits, battery chargers, switching mode power supplies, digital watt meters, programmable current sources, etc. This ACS721 current module is based on ACS712 sensor, which can accurately detect AC or DC current. The maximum AC or DC that can be detected can reach 20A, and the present current signal can be read via analog I / O port of Arduino.
