SF-SEN-11207

This is a piezoresistive force sensor from Tekscan. The harder you press, the lower the sensor’s resistance. Pressing hard, the resistance changes from infinite to ~50k. The sensor itself is thin and flexible, but the resistance does not change while being flexed. Resistance c...

SF-SEN-12728

Infrared proximity sensor made by Sharp. Part # GP2Y0A41SK0F has an analog output that varies from 3.1V at 4cm to 0.3V at 30cm with a supply voltage between 4.5 and 5.5VDC. The sensor has a Japanese Solderless Terminal (JST) Connector. We recommend purchasing the related pigta...

DF-DFR0033

what's the best way to detect the magnet? Use anther magnet. But it's not sensitive enough. You have to feel it by youself.Right.This magnetic sensor knows whether there is a magnetic object nearby or not. And it correctly tells you through ditigal output.See below picture for...

SF-SEN-13322

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, together acting as a variable resistor. Th...

SF-COM-10601

This is a small device called a reed switch. When the device is exposed to a magnetic field, the two ferrous materials inside the switch pull together and the switch closes. When the magnetic field is removed, the reeds separate and the switch opens. This makes for a great non...

PL-2458

Note: The QTR-1A reflectance sensor requires an analog input to take readings. The similar QTR-1RC reflectance sensor is available with a digital I/O-compatible output.

PL-2599

These are the same magnetic discs we include with our magnetic encoder pair kit for micro metal gearmotors. They are 2 mm thick with a 7.65 mm diameter, and the hole through the center enables them to securely press-fit onto the 1mm-diameter motor shafts of our micro metal ge...

SF-SEN-13637

The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straightforward to use. The two large, exposed pads function as probes for the sensor, together acting as a variable resistor. Th...

SF-SEN-10313

This tilt sensor can be used to detect multiple orientations. Inside the sensor are infrared emitters which are either reflected or not, depending on the orientation of the sensor. By reading the output of the various pins you can easily determine the orientation of the sensor...

Overview

SF-SEN-13723

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? This is the MyoWare Muscle Sensor, an Arduino-powered, all-...

DF-DFR0034

This is a new Arduino compatible Analog Sound Sensor. Sound Sensor is typically used in detecting the loudness in ambient, the Arduino can collect its output signal and actuate accordingly. You may use it to make some funny interactive works such as a "clap and buzz" to find ...

SF-BOB-08688

Basic breakout board for the TEMT6000 Ambient Light Sensor. Only what you need, nothing you don’t. Sensor acts like a transistor - the greater the incoming light, the higher the analog voltage on the signal pin.

DF-DFR0009

This is a very popular LCD Keypad shield for Arduino and other variants. It includes a 2x16 LCD display and 6 momentary push buttons. Pins 4, 5, 6, 7, 8, 9 and 10 are used to interface with the LCD. Just one Analog Pin 0 is used to read the five pushbuttons. The LCD shield sup...

Finally we have an I2C-interface temperature & humidity sensor in a nice enclosed style.

LB-LR0157

The Sharp GP2Y0A710K0F IR Range Sensor takes a continuous distance reading and reports the distance as an analog voltage with a distance range of 100cm to 550cm. 

LB-00321

Measures distance range: 20 to 150 cm

DF-DFR0094

Infrared devices are widely used, and often for remote controlled devices. With this IR receiver, your Arduino project is now able to receive command from any IR remote controller.

AF-2472

If you've ever ordered and wire up a 9-DOF sensor, chances are you've also realized the challenge of turning the sensor data from an accelerometer, gyroscope and magnetometer into actual "3D space orientation"! Orientation is a hard problem to solve. The sensor fusion algorith...

SF-ROB-09454

This version of the QRE1113 breakout board features a digital output, using a capacitor discharge circuit to measure the amount of reflection. This tiny board is perfect for line sensing when only digital I/O is available, and can be used in both 3.3V and 5V systems.

AF-3251

It's summer and you're sweating and your hair's all frizzy and all you really want to know is why the weatherman said this morning that today's relative humidity would max out at a perfectly reasonable 42% when it feels more like 77%. Enter the Si7021 Temperature + Humidity Se...
