ACS712 - 20A Range Current Sensor Module
Description:
The ACS712 - 20A Range Current Sensor Module is similar to the 5A variant but is designed to handle higher currents, up to 20 amps. Here's how you might use it:
-
Current Measurement: Like the 5A variant, the primary function of the ACS712 - 20A Range module is to measure current. It allows you to monitor the amount of current flowing through a circuit.
-
Non-Invasive Measurement: Just like its lower-range counterpart, this module is non-invasive. You pass the current-carrying wire through the sensor's central hole, and it measures the current without the need to break the circuit.
-
Analog Output: The ACS712 - 20A Range module also provides an analog output voltage proportional to the measured current. This voltage can be read by an analog-to-digital converter (ADC) on a microcontroller like Arduino to obtain the current value.
-
Overcurrent Protection: By continuously monitoring the current using the ACS712 - 20A Range module, you can implement overcurrent protection mechanisms in your projects. If the current exceeds a predetermined threshold, you can trigger actions such as shutting down a system or activating a warning.
-
Power Monitoring: Similar to the 5A variant, you can use the ACS712 - 20A Range module to monitor power consumption in devices or systems. By integrating the measured current over time, you can calculate the total energy consumed.
-
Feedback Control: In applications where precise current control is essential, such as motor control, the ACS712 - 20A Range module can provide feedback for closed-loop control algorithms.
To use the ACS712 - 20A Range Current Sensor Module with an Arduino or similar microcontroller, the connection and usage are similar to the 5A variant. You connect the VCC and GND pins of the module to the appropriate power and ground pins on the microcontroller, and the OUT pin to one of the analog input pins. Then, in your Arduino code, you read the analog voltage from the sensor and convert it to a current value using calibration factors provided in the datasheet or determined experimentally.
