LB-LR0240

With the sound module, we can detect the presence of loud sounds. While this module has a microphone on it, our Arduino does not have the brains to interpret or record the audio directly (there are some shields you can get that will do this).

LB-LR0214-37

Pulse sensor Pulse Heart Rate Sensor Module

LB-LR0214-73A

Secure your project with biometrics - this all-in-one optical fingerprint sensor will make adding fingerprint detection and verification super simple.

LB-LR0045

Arduino to SD card interface module.Use this to read and write to the SD card using your arduino.

LB-LS0835

Do you love your plants? Do you want the best for them? Or are you more like me and forget they are there until your mother is about to come over then rush round the house making sure they have been watered? Either way this kit is for you!

DF-DFR0067

DFRobot's latest generation of digital DHT11 Temperature and Humidity sensor is as powerful as it used to be but easier to use.

SU-TS0225

When wired with a 5v supply, the power light will be on.

LB-LR20

45 sensors for Arduino

AF-161

CdS cells are little light sensors. As the squiggly face is exposed to more light, the resistance goes down. When its light, the resistance is about 5-10KΩ, when dark it goes up to 200KΩ.

SF-SEN-00245

This is the latest DS18B20 1-Wire digital temperature sensor from Maxim IC. Reports degrees C with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each sensor has a unique 64-Bit Serial number etched into it - allows for a huge number of sensors to be used on one data bus. This...

AF-3085

The Prop Shield with Motion Sensors for Teensy 3.2 and Teensy-LC is meant for making interactive light and sound effects on small handheld props and wearable costumes! Good for all sorts of projects, and designed by the creator of the Teensy so you know it's gonna be well supp...

LB-LR0214-47

This is a touch sensor for Arduino.   This sensor is a toggle output type: touch-on then touch-off.

LB-LR0044

The MPU-6050 sensor contains a MEMS accelerometer and a MEMS gyro in a single chip. It is very accurate, since it contains 16-bits analog to digital conversion hardware for each channel. Therefor it captures the x, y, and z channel at the same time.

AF-1740

This small (14mm diameter) piezo element is nicely enclosed so you can attach easily. Piezo elements convert vibration to voltage or voltage to vibration. That means you can use this as a buzzer for making beeps, tones and alerts AND you can use it as a sensor, to detect fast ...

DF-DFR0039

We designed this board to give the user a very discrete button without any sharp edges. Button closes when you push it and opens when you release (momentary push button).

DF-DFR0021-W

This white LED light module has a shiny white color. It is ideal for Arduino starter. This module can be easy to be plugged on IO/Sensor expansion shield.

DF-SEN0138-L

A miniature snap-action switch, also trademarked and frequently known as a micro switch, is an electric switch that is actuated by very little physical force.Micro switches are very widely used; among their applications are appliances, machinery, industrial controls, vehicles,...

SF-SEN-10167

The RHT03 (also known by DHT-22) is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesn’t require extra components so you can get right to measuring relative humidity and temperature.

SF-SEN-11999

These simple switches are the Mechanical Bumper sensor for the SparkFun RedBot, giving you the ability to detect a collision before it really happens. This sensor works by acting as a SPST switch. When the “whisker” bumps into a foreign object it will make contact with a nut n...

LB-LR0298

This stand alone DHT11 can read the temperature and humidity and send the information over a one wire, simplex serial bus. Arduino.cc provides a DHT11 library to aid in communicating with this module.

DF-DFR0151

The DS1307 Real Time Clock module developed by one of our designers: Waiman. The module comes fully assembled and pre-programmed with the current time (ok, so it's our current time - MST). The included Lithium coin cell battery (CR1225 41mAh) will run the module for a minimu...

SF-SEN-10988

This is the same temperature sensor that is included in our SparkFun Inventor’s Kit. The TMP36 is a low voltage, precision centigrade temperature sensor. It provides a voltage output that is linearly proportional to the Celsius temperature. It also doesn’t require any external...

DF-SER0037

This small form factor micro servo with 360 degree continuous rotation is compatible with servo shields for Arduino. It's a very versatile small servo motor for micro robots or other applications where you don't have much space and the need of a full rotational motor with the ...

DF-DFR0024

While there are many types of temperature sensors available in the market, the DS18B20 arduino Temperature Sensor form DALLAS is the best choice in applications which require high accuracy and high reliability. Its ultra-small size, low hardware overhead, strong anti-interfere...
