ACS712 Arduino Current Sensor<\/h3>\n

ACS712 Arduino Current Sensor is a\u00a0simplified approach<\/strong>\u00a0to my prior Instructable regarding measuring AC current with the ACS712 current sensor..<\/p>\n

Simplifications include:<\/u><\/p>\n

    \n
  1. Eliminating the special Signal Conditioning Circuit Board – instead we’re going to use the “RunningStatistics” function available in the Ardunio\u00a0Filters<\/em>library.<\/li>\n
  2. Eliminating the need to build a special extension cord to “splice-in” the ACS712 Module, instead we’ll be hacking an inexpensive wireless remote receiver outlet.In addition to being much simpler, this approach results in a more compact, professional looking form factor.<\/li>\n<\/ol>\n

    As a review from my prior Instructable,\u00a0the challenge<\/strong>\u00a0with using the ACS712 sensor is that measuring AC current with the ACS712 module yields an output signal sine wave centered around 1\/2 Vcc\u00a0regardless<\/strong>\u00a0of the AC current draw, only the\u00a0peak-to-peak fluctuation<\/strong>\u00a0about the center line increases as the AC current drawn increases (see photo of oscilloscope images). Thus, the Arduino normal “analogRead value” won’t change regardless of the AC current being drawn. This is where the Arduino\u00a0Filters<\/i>\u00a0library “Running Statistics” function’s ability to measure the\u00a0fluctuation<\/strong>\u00a0comes in.

    The device consists of a precise, low-offset, linear Hall sensor circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer. A precise, proportional voltage is provided by the low-offset, chopper-stabilized BiCMOS Hall IC, which is programmed for accuracy after packaging. The output of the device has a positive slope (>VIOUT(Q)) when an increasing current flows through the primary copper conduction path (from pins 1 and 2, to pins 3 and 4), which is the path used for current sensing. The internal resistance of this conductive path is 1.2 m\u03a9 typical, providing low power<\/p>\n","protected":false},"excerpt":{"rendered":"
