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...

The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straight forward to use. The two large exposed pads function as probes for the sensor,...

The SparkFun Qwiic Adapter provides the perfect means to make any old I 2 C board into a Qwiic-enabled board. This adapter breaks out the I 2 C pins from the Qwiic connectors to pins that you can easily solder with your favorite I 2...

This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only...

These are extremely handy and comfortable to use wire strippers from Hakko. These are an essential part to any hacker’s arsenal and are able to strip 30AWG wire wrap wire nicely as well as the standard 22AWG hook up wire. Features: 30,...

This disc load cell (sometimes called a strain gauge) can translate up to a whopping 200kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and...

This is the SparkFun MiniGen Signal Generator, a small shield for the Arduino Pro Mini that is capable of generating sine, square, or triangle waves at up to 3MHz, and approximately 1Vp-p. Though the MiniGen is technically a shield it...

The SparkFun 9DoF Razor IMU M0 combines a SAMD21 microprocessor with an MPU-9250 9DoF (9 Degrees of Freedom) sensor to create a tiny, reprogrammable, multipurpose IMU (Inertial Measurement Unit). It can be programmed to monitor and log...

This is a 10 pack of Biomedical Sensor Pads, disposable electrodes that can be used to measure EEG, ECG and EMG levels. these little pads are perfect for short-term monitoring of Neurofeedback and Biofeedback purposes. They are to be...

The LilyPad XBee is a breakout board for the popular XBee modules that can be sewn into your e-textile projects to provide them with a little “connectivity.” This board includes easy-to-sew tabs and all the necessary power regulation to...

Arduino Example Code Using our muscles to control things is the way that most of us are accustomed to doing it. We push buttons, pull levers, move joysticks…but what if we could take the buttons, levers and joysticks out of the equation?...

A simple flex sensor 4.5" in length. As the sensor is flexed, the resistance across the sensor increases. Patented technology by Spectra Symbol - they claim these sensors were used in the original Nintendo Power Glove . I love the...
