SF-COM-09312

The US1881 is an integrated Hall effect latched sensor. That’s nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulatio...

FT-LIGHT

Does the fridge light really turn off? Now you can find out!

LB-LR0043

The Water Sensor is a small analogue sensor which can detect the amount of water there is on itself. The value will increase as the more water is put onto it. This can be used as a simple water level meter. All that you need to do to connect this sensor to your project is thre...

INTRODUCTION

DF-SER0011

This is a metal gear servo(2.5kg) from Goteck.It's very small, lightweight, and powerful! Metal gear for longer wear life and extra strength in demanding applications. Perfect for use in medium-sized electric airplanes,helicopters or mini Robots.

SF-SEN-08880

This alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer. It has a high sensitivity and fast response time. Sensor provides an analog resistive output based on alcohol concentration. The drive circuit is very simple...

DF-SEN0171

This is a PIR(passive infrared motion) sensor designed to work with Arduino and Raspberry Pi. It allows you to sense motion, it is commonly used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't we...

AF-2106

The Leap Motion Controller captures the movement of your hands and fingers so you can interact with your computer in a whole new way.

DF-DFR0032

Here is the simplest sound making module that you can use High/Low to drive it. Just change the frequency it buzz, you can hear different sound. It is widely used on your daily application, like PC, refrigerator,phones and so on. And you also can create many interesting inter...

DF-FIT0180

This type of photoresistor is made of environment-friendly materials(no Cadmium and Lead) compared with the traditional CDS photoresistor.

SF-SEN-10264

A simple flex sensor 2.2" 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 Nintendo Power Glove. It’s so bad!

SF-DEV-09281

The WiiChuck Adapter is a small PCB that is designed to be inserted into the connector of a Nintendo Wii Nunchuck to provide access to all 4 wires of the remote. The power, ground and two-wire interface of the Nunchuck are all broken out to a 4-pin 0.1" pitch header.

DF-DFR0198

This is a waterproofed version of the DS18B20 Temperature sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you ...

FT-HALL

 Sense magnetic presence, rotating wheels and magnets, door and arm sensors, and anything else magnetic nearby this sensor.

FT-SOUND

This versatile piezo-element module can be used for both input or output! It can be used as a noise-maker driven by your microcontroller for audible feedback of events, and it can also be used as a knock-detector input to sense events and react to them. Includes a built-in 1M ...

FT-TEMP

Sprinkle these around your house to collect temperature data using your Arduino. This DS18B20-based 1-wire bus temperature sensor module is easy to connect and use, and you can even daisy-chain several together on the same wire. 0.5°C accuracy and fast response.

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...
