  • Current Sensor - 30A (Non-Invasive)

    This non-invasive current sensor (also known as a “split core current transformer”) can be clamped around the supply line of an electrical load to tell you how much current is passing through it. It does this by acting as an inductor and responding to the magnetic field around a current-carrying conductor. By reading the amount of current being produced by the coil, you can calculate how much current is passing through the conductor. This particular current sensor will measure a load up to 30 Amps which makes it great for building your own energy monitor to keep your power usage down, or even building an over-current protection device for an AC load. This sensor does not have a load resistor built in, so in most cases it will be necessary to place a resistor across the output to convert the coil’s induced current to a very small measurable voltage.

  • Electromagnet -Grove - An electromagnet is a type of magnet in which the magnetic field is produced by electric current. An electric current flowing in a wire creates a magnetic field around the wire, due to Ampere's law(see drawing below). To concentrate the magnetic field, in an electromagnet the wire is wound into a coil with many turns of wire lying side by side. The magnetic field of all the turns of wire passes through the center of the coil, creating a strong magnetic field there. Grove - Electromagnet can shuck 1KG weight and hold on. it easy to use, to learn electromagnet principle. Features Grove shape 1KG peak suction Low standby current Specification Working Voltage :DC 5V Working Current : 400mA Standby current : 200uA Load Weight: 1KG CODE: /* Turns on an Electromagnet on for one second, then off for one second, repeatedly. This example code is in the public domain. */ int Electromagnet = 0; int LED = 13; // the setup routine runs once when you press reset: void setup() { // initialize the digital pin as an output. pinMode(Electromagnet, OUTPUT); pinMode(LED, OUTPUT); } // the loop routine runs over and over again forever: void loop() { digitalWrite(Electromagnet, HIGH); // turn the Electromagnet on (HIGH is the voltage level) digitalWrite(LED, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(Electromagnet, LOW);// turn the Electromagnet off by making the voltage LOW digitalWrite(LED, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second }

  • SparkFun Hall-Effect Current Sensor Breakout - ACS712

    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. Thick copper conductor and signal traces allows for survival of the device up to 5 times overcurrent conditions. The ACS712 outputs an analog voltage output signal that varies linearly with sensed current. The device requires 5VDC for VCC and a couple of filter capacitors.

  • Voice Recorder Breakout - ISD1932

    This is a breakout board for the ISD1932, a multiple-message record/playback device. This single chip can record up to 64 seconds worth of voice messages. Microphone inputs and speaker outputs are all handled by the ISD1932. A switch is connected to allow selection of the ISD1932’s operating mode - address trigger or direct trigger. You must cycle the power after switching the mode. An LED is also populated on the board and will illuminate when the device is recording. An external resistor is necessary to select the record duration and sampling frequency, which can range from 21.2 - 64 seconds (4-12kHz sampling frequency). The board breaks out all pins of the ISD1932 to 0.1" spaced headers. This product comes as shown in the pictures with filtering capacitors, an LED, mode selecting switch and the ISD1932 IC. The new version of this board also includes a microphone and a 3.5mm audio jack.
