ACS712 Current Sensor- 20A

Sensing and controlling current flow is crucial in numerous applications such as over - current protection circuits, battery chargers, switching mode power supplies, digital watt meters, and programmable current sources. This ACS712 current module, based on the reliable ACS712 sensor, can precisely detect both AC and DC current. It can detect a maximum AC or DC current of up to 20A. You can easily read the current signal via the analog I/O port of an Arduino. Additionally, there are 5A and 30A versions available for your selection. Specification: Supply Voltage ranges from 4.5V to 5.5V DC, Measure Current Range is from -20A to 20A, and Sensitivity is 100mV/A.

Using this 20A ACS712 Current Sensor Module is easy. First, make sure to connect it to a power supply with a voltage between 4.5V and 5.5V DC. This will power up the module and let it start working. To measure the current, just connect the relevant circuits to the sensor. You can then read the current signal through the analog I/O port of your Arduino. When choosing the right version for your project, keep in mind that there are 5A and 30A versions available in addition to the 20A one. Be careful not to exceed the maximum current limit of 20A, as this could damage the sensor. When it comes to maintenance, keep the sensor in a dry and clean environment.
