As you can see the quality is really great, the silkscreen is quite clear and the black solder mask looks amazing. */ LiquidCrystal lcd(7, 8, 9, 10, 11, 12); /* Vcc on carrier board to Arduino +5v GND on carrier board to Arduino GND OUT on carrier board to Arduino A0 Insert the power lugs into the loads positive lead circuit, arrow on carrier board points to load, other lug connects to power supply positive Voltage Divider 11.66 from + to A4 4.62k from A4 to Gnd Ratio 2.5238 */ int batMonPin = A4;    // input pin for the voltage divider int batVal = 0;       // variable for the A/D value float pinVoltage = 0; // variable to hold the calculated voltage float batteryVoltage = 0; int analogInPin = A0;  // Analog input pin that the carrier board OUT is connected to int sensorValue = 0;        // value read from the carrier board int outputValue = 0;        // output in milliamps unsigned long msec = 0; float time = 0.0; int sample = 0; float totalCharge = 0.0; float averageAmps = 0.0; float ampSeconds = 0.0; float ampHours = 0.0; float wattHours = 0.0; float amps = 0.0; int R1 = 11660; // Resistance of R1 in ohms int R2 = 4620; // Resistance of R2 in ohms float ratio = 0;  // Calculated from R1 / R2 void setup() {   // initialize serial communications at 9600 bps:   Serial.begin(9600);   lcd.begin(20, 4); } void loop() {   int sampleBVal = 0; int avgBVal = 0;  int sampleAmpVal = 0; int avgSAV = 0;   for (int x = 0; x < 10; x++){ // run through loop 10x   // read the analog in value:   sensorValue = analogRead(analogInPin);     sampleAmpVal = sampleAmpVal + sensorValue; // add samples together   batVal = analogRead(batMonPin);    // read the voltage on the divider   sampleBVal = sampleBVal + batVal; // add samples together     delay (10); // let ADC settle before next sample } avgSAV = sampleAmpVal / 10;   // convert to milli amps   outputValue = (((long)avgSAV * 5000 / 1024) - 500 ) * 1000 / 133;    /* sensor outputs about 100 at rest. This output voltage is measured with the help of arduino or any microcontroller.

We can measure current by using above three lines of Arduino code. You can see the result on the LCD but also on the serial monitor.

Arduino to LCD projects – Using 3 Different... Charlieplexing LEDs With The Arduino Board, AutoCAD Tutorial 04: How to Draw A Line With An Angle in AutoCAD.

As you can see, it is fairly a simple board with only a few components including the ASC712 IC, few passive components and connectors. Vcc pin of current sensor module is connected with 5V pin of Arduino and Ground pin is connected with Ground pin of Arduino and output pin of current sensor module is connected with Analog channel 0 of Arduino which built in analog to digital converter of Arduino… I am 100% satisfied with their work…. Please explain me about the Arduino code.

In third line, measured voltage is subtracted from offset voltage and divided by sensitivity factor to get current from measured voltage. .00488 is ideal. To calculate current from output voltage of acs712 current sensor, you should make calculations according to following points: figure below shows the connection diagram of interfacing acs712 current sensor with arduino.

Measuring voltages (DC Voltages) with Arduino is very easy. Best Waveform Generators

In this project, we will learn about measuring current using a Current Sensor (ACS712 Current Sensor to be specific). With this project, we are going to be working with a less popular sensor that we have been so far: the current sensor. NOTE! I was you to help with a diagram the can make me measure the current after and before an energy meter. Interfacing Knock Sensor with Arduino (Vibration/Tap Sensor).

Best Brushless Motors In this project, we will discuss about ACS712 Current Sensor, how a Hall Effect based current sensor works and finally how to interface the ACS712 Current Sensor with Arduino. If you recall the previous Arduino project, I have discussed about measuring voltages greater than 5V with Arduino using a Voltage Sensor. Arduino Sensors

It seems quite impractical to use the laptop for only monitoring the current value.

So, Interfacing an ACS712 Current Sensor with Arduino helps us in measuring current with the help of Arduino. monitor                                     at load or supply and decide. The above code can be used for all of the three types of sensors 5 ampere, 20 ampere and 30 ampere current sensor. This time I add the 16×2 LCD.

For my off-grid Ham Radio and Solar projects, I needed a way to measure volts, amps, watts, amp hours and watt hours. googletag.cmd.push(function() { googletag.display("div-gpt-ad-1527869606268-4"); });

Inside the IC there is a sensing resistor and it’s across these two Blue color terminals. So, that’s all about the programming. (adsbygoogle = window.adsbygoogle || []).push({}); Pin out of acs712 current sensor is given below. Arduino Starter Kit

Automotive Applications like Inverters, Power Steering etc. If you give dc current to its input , it will give proportional dc voltage at the output of sensor and if you give ac current at the input of acs712, it will give you proportional ac voltage at the output.

I will also update this article on how to measure ac current with acs712 hall effect sensor.
