Overview

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.

AF-1375

This breakout board is the simplest way to create a project with a single "toggle" capacitive touch sensor.

DF-DFR0079

This LilyPad Power Supply is Discontinued Now, We recommend other best selling Power Modules as a suitable replacement.

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

We carry a few different GPS modules here in the Adafruit shop, but none that satisfied our every desire - that's why we designed this little GPS breakout board. We believe this is the Ultimate GPS module, so we named it that. It's got everything you want and more:

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.

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.

SF-WRL-14147

Ever wanted to play with those newfangled RFID tags? Although it’s been around for a while, the technology has been extremely cost-prohibitive and difficult to implement without being an RF engineer. This affordable product opens the door for using RFID in your own projects!

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...

DF-SEN0019

This is an Arduino infrared distance sensor. It has an adjustable detection range, 3cm - 80cm. It is small, easy to use, assemble, and inexpensive.

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...

SF-SEN-00241

Side-looking Infrared Emitters and IR Detectors. These simple devices operate at 940nm and work well for generic IR systems including remote control and touch-less object sensing. Using a simple ADC on any microcontroller will allow variable readings to be collected from the d...

To shy to confess? A beating heart might help you out. Express it. Display it, with this tiny, portable, magic LED matrix!

DF-DFR0130-R

This is a standalone DC voltage meter. It measures 3V-30V with 1% accuracy. Best suited for battery level display. Just apply two wires on the power without any extra circuit or components, it gives the reading straight away. Easy to use, and is a good company with robotic a...

SF-SEN-12617

Knowing where your robot is can be very important! The RedBot Wheel Encoder allows you to track the number of revolutions each wheel has made. This sensor works by detecting the movement of small teeth connected to a motor through the reflection of infrared light. By measuring...

AF-375

This sensor is essentially a reed switch, encased in an ABS plastic shell. Normally the reed is 'open' (no connection between the two wires). The other half is a magnet. When the magnet is less than 13mm (0.5") away, the reed switch closes. They're often used to detect when a ...

DF-DFR0362

Wireless charging uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device.

DF-FIT0200

This immersible pump can be used to water your plants, make a fountain or waterfall, even change your fish tank wter.It works quietly with the sound level under 30db.

PL-1479

Overview

FT-MIC

Give your project ears with this sound response and sound pressure level sensing module. An integrated dual signal amplifier converts the sound to separate channels for pulse / frequency measurement, and sound volume (pressure) level. Designed to connect straight to an Arduino...

SF-SEN-11769

The Line Follower sensor is an add-on for your RedBot that gives your robot the ability to detect lines or nearby objects. The sensor works by detecting reflected light coming from its own infrared LED. By measuring the amount of reflected infrared light, it can detect transit...
