I have a voltage sensor, and I want to measure a battery lipo power output, so It’s voltage range can reach between 10-12,5 V and the current can reach 0-20 A. This demo will use EVAL-ADXL372-ARDZ shield along with Arduino Uno base board to create a impact measurement application, using the Arduino IDE. How to make a circuit for voltage and current measurement using Arduino and ACS712, ADS1015. The FIDI chip on the Arduino, which helps the microcontroller talk with your computer through the USB cable, also has an on-board voltage regulator that outputs 3. As to voltage, there is a set of dividing voltage. The three lab examples included here are measurements of device current-voltage (I-V) characteristics and measurement of amplifier and filter frequency response characteristics. Using LDR to display light level on 16X2 LCD [ARDUINO] Button Counter using 7 segment display [ARDUINO] Temperature and Humidity display on 16X2 LCD with DHT11 Sensor [ARDUINO] Detecting motion using HC-SR501 PIR Sensor [ARDUINO] Using HC-05 Bluetooth Module - Control an LED with an Android phone [ARDUINO]. This board aims to provide a platform for innovative projects in smart IoT devices, wearable technology, high-tech automation, crazy robotics, and much more. To measuring the power factor with microcontrollers in the first we used Op-Amp to zero cross detection to find the phase shift between current and voltage phase, the op-amp convert the sine wave signal comes from CT and PT with different amplitude to square wave with about 4v amplitude, then we connect these two square wave to XOR gate inputs. General Description/Overview The ADXL372_example project uses the EVAL-ADXL372-ARDZ shield which has an ADXL372 accelerometer. Connect the accelerometer to the Arduino ; each output pin goes to one of the analog pins on the Arduino, the Vin pin goes to the 5V pin on the Arduino (read the user guide to ensure the Vin pin is 5V as opposed to 3. 7) IP- is positive terminal for load. The cool thing about an ACS712 is that current is measured is measured in two directions. Max current = 100mA. Better, its really easy to use with an Arduino. Read DC current. d) To maximise measurement resolution, the voltage across the burden resistor at peak-current should be equal to one-half of the Arduino analog reference voltage. 3) You can then use a 220 Ω commercially available resistor. 5 digit handheld digital multimeter, which has a maximum current rating of 10 A. This guide details how to build a simple electricity energy monitor on that can be used to measure how much electrical energy you use in your home.
