CURRENT MEASUREMENT SENSORS Experiment 3 Time : 3 hours Equipment 3 x multimeters ACS712 Hall current sensor AC1005 CT sensor Dual DC bench power supply 3A 240VAC variac 12V transformer 3x 12v 21/5W bulbs Preliminary •Read up on Hall effect so you understand what you are seeing in part 1 of the experiment. He asked me to design and develop some instrumentation using the arduino Due development board. Sensing and controlling current flow is a fundamental requirement in a wide variety of applications including, over-current protection circuits, battery chargers, switching mode power supplies, digital watt meters, programmable current sources, etc. Arduino Current Sensor This Arduino based current, voltage, and power sensor/meter tutorial was created for hacktronics by Steve Spence. While the ACS712 IC is still being used as a current sensor for projects, if you are creating a new design application, it is recommended that you use the ACS723. Use the current output SCT with adequate burden resistor instead. This is a breakout board for the fully integrated Hall Effect based linear ACS712 current sensor. The sensor gives precise current measurement for both AC and DC signals. IC ACS712 a simple linear current sensor form the. I am going to measure current using a hall effect sensor by allegro ' Acs712'. 00 The ACS712 Current Sensor has a -5A to +5A range and is compatible to microcontrollers like Arduino. More Information: How to Measure AC Current Using Hall Effect Sensor With Arduino or Other Common Microcontrollers; Notes: Products may vary slightly from images and. The device consists of a precise, low-offset, linear Hall sensor circuit with a copper conduction path located near the surface of the die. I'm relatively new to electronics. Non-invasive AC Current Sensors are a good way to measure real consumption without altering the electrical composition of the elements to be analyzed. I also tested the "ACS712. com FREE DELIVERY possible on eligible purchases. We added an opamp gain stage for more sensitive current measurements. There are a wide variety of sensors, and each sensor is suitable for a specific current range and environmental condition. Specifications:-Supply Voltage: 4.
