Current Transformer for AC Measurement Using aCurrent transformer for measuring AC currentis a very safe approach because there is no physical connection between the measurement circuit and the AC current carrying wire. Hence, current transformer is used in industry to measure the high AC current va...
Pitch += 1 * gyro_rateX * dt; // Current Angle around the X-axis Roll += 1 * gyro_rateY * dt; // Current Angle around the Y-axis Yaw += 1 * gyro_rateZ * dt; // Current Angle around the Z-axis delay (10); } starttime = micros(); // Start time for the next Measure...
Measurement Now we’re ready to start measuring some capacitors. Insert an unknown capacitor into the breadboard as shown in the diagram above. Then open the serial monitor to see the time constant and capacitance values. These are the readings I got from a 470 μF electrolytic capacitor: The...

In the next sections, I introduce you to the library by replicating our DC current measurement from before but now using theACS712 library. Then we change the code a tiny bit to measure AC currents. And finally, we are going to add the code to display our measurements on the LCD again...
float mVNoiseLevel(float frequency, uint16_t cycles)determines the mV of noise. Measurement should be taken when there is no AC/DC current or a constant DC current. The level will give a (not quantified yet) indication of the accuracy of the measurements. A first order indication can be ...
Part 1 – Direct Current In the first part of our look at measuring voltage and current with microcontrollers, we will see how to measure DC voltage and current using an Arduino. In part two we will do the same thing with AC, but today our focus is on Direct Current. Introduction There...

Step 5: Current Measurment For current measurement we will use a Hall Effect current sensor ACS 712 (30 A). WORKING PRINCIPLE : The Hall Effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and ...
