average_current = average_current / SAMPLES; // print out the current to serial monitor Serial.print("Current: "); Serial.println(average_current); delay(100); //just a small delay } 代码中SAMPLES取值为10。SAMPLES值越大,输出越清晰,但有可能降低Arduino的运行。
In this blog post, you will learn how to use the ACS712 current sensor with an Arduino to measure DC and AC currents. By the end of this tutorial, you will have a clear understanding of how the ACS712 sensor works, how to connect it to an Arduino, and how to read and display curr...
and therefore the resolution, of the device output signal. However, the addition of an RC filter to the output of a sensor IC can result in undesirable device output attenuation — even for DC signals
ACS712(uint8_t analogPin, float volts = 5.0, uint16_t maxADC = 1023, float mVperAmpere = 100)constructor. It defaults a 20 A type sensor, which is defined by the default value of mVperAmpere. See table below. Volts is the voltage used by the (Arduino) internal ADC. maxADC is t...
