  Fingerprint Slide Scanner
This is a low-cost finger print scanner with a slide type sensor where the user slides their finger over the scanner. The ARA-ME-01 uses a simple serial interface that makes identifying users by their finger print fast and easy. This scanner is capable of gathering and storing unique finger prints. Simply hold your finger on the optical scanner, query the device over serial, and you will be issued a unique ID. Use that ID within your embedded system to determine access levels, time clocks, door locks, etc. Unit includes scanning element and control board. We are trying to get pigtail interface cables made but in the interim, you will need to create your own connection to the serial connector. Features: 9600bps TTL serial interface 5V@60mA supply 256*288 sensor resolution Memory for 120 fingerprints
  Ultrasonic Range Finder - Maxbotix HRLV-EZ4
These easy-to-use ultrasonic rangefinders from Maxbotix work the same way as the EZ line that you know and love, but this new high-resolution series features 1 millimeter resolution! As with the rest of the Maxbotix range finders, these sensors feature Analog Voltage, RS232 Serial, and Pulse Width outputs making them easy to interface with any microcontroller. These sensors have a maximum range of 5000 mm (195 inches) with virtually no dead zone (although objects closer than 30 cm will typically range as 30 cm). We're offering the EZ0, EZ1, and EZ4 with progressively narrower beam angles allowing the sensor to match the application. Please see beam width explanation below. Control up to 10 sensors with only two pins! Checkout the Maxbotix FAQ listed below. Features: 42kHz Ultrasonic sensor Operates from 2.5-5.5V Low 3.1mA average current requirement 10Hz reading rate Analog Voltage, RS232 or TTL Serial, and Pulse Width Small, light weight module
  SoftPot Membrane Potentiometer - 50mm
SoftPots are a series of extremely thin potentiometers that can be used as position sensors for robots or as a control surface (volume level input for example). The resistance changes linearly from 100ohms to 10kohm when any part of the track is pressed. If no part is pressed, the circuit is open and may need a pull-up/down resistor to prevent random or incorrect readings. All SoftPots have adhesive backing. Connector is 2.54mm spaced and fits breadboards. The headers are slightly too thin to fit well in female headers (regular IC-sockets work better). Length: 50mm Thickness: 0.5mm Power rating: 1W

  APDS-9960 RGB- och rörelsesensor
This is the SparkFun RGB and Gesture Sensor, a small breakout board with a built in APDS-9960 sensor that offers ambient light and color measuring, proximity detection, and touchless gesture sensing. With this RGB and Gesture Sensor you will be able to control a computer, microcontroller, robot, and more with a simple swipe of your hand! This is, in fact, the same sensor that the Samsung Galaxy S5 uses and is probably one of the best gesture sensors on the market for the price. The APDS-9960 is a serious little piece of hardware with built in UV and IR blocking filters, four separate diodes sensitive to different directions, and an I2C compatible interface. For your convenience we have broken out the following pins: VL (optional power to IR LED), GND (Ground), VCC (power to APDS-9960 sensor), SDA (I2C data), SCL (I2C clock), and INT (interrupt). Each APDS-9960 also has a detection range of 4 to 8 inches (10 to 20 cm).
  Distance sensor digital output 2 - 10cm GP2Y0D810Z0F
If you're like me, you've always wanted a smaller and faster way to sense an object between 2 and 10 centimeters away. If you're really like me, you've wanted the sensor to come with a low current draw and on a tiny carrier board with all of the external components required to make it work. The Polulu Carrier with Sharp GP2Y0D810Z0F Digital Distance Sensor fits those both needs and more. it's one of Sharp's fastest distance sensors - with a sample rate of almost 400 Hz and is an attractive alternative to short range phototransistors and longer range analog distance sensors. Output is high normally and low when the sensor detects an object. This sensor only tells if the object's nearby - not how near or far the sensor is - so they're great for break-beam, obstacle detection, and object counting. This sensor comes with a 3-pin male header and a 3-pin right-angle male header. You can connect these pins with a servo cable. The square pad is ground, middle is VIN, and the remaining pad is output. If you place a large capacitor (more than 10uF) between power and ground you should see an increase in performance. Dimensions: 22mm x 9mm x 10mm / 0.9" x 0.4" x 0.4" Weight: 1.3g Operating Voltage: 2.7 V to 6.2 V Average Current Consumption: 5 mA Distance Measuring Range: 20mm to 100mm / 0.8" to 3.9" Steady State Update Period: 2.56ms Sample Rate: ~400 Hz
  6 Degrees of Freedom - LSM6DS3 Breakout
The LSM6DS3 is a accelerometer and gyroscope sensor with a giant 8kb FIFO buffer and embedded processing interrupt functions, specifically targeted at the cellphone market. Due to the capabilities and low cost of the LSM6DS3 weve created this small breakout board just for you! Each LSM6DS3 Breakout has been designed to be super-flexible and can be configured specifically for many applications. With the LSM6DS3 Breakout you will be able to detect shocks, tilt, motion, taps, count steps, and even read the temperature!The LSM6DS3 is capable of reading accelerometer data up to 6.7kS/s and gyroscope data up to 1.7kS/s for more accurate movement sensing. As stated before this breakout also has the ability to buffer up to 8kB of data between reads, host other sensors, and drive interrupt pins all thanks to the LSM6DS3s built-in FIFO.Each pin has been broken out on the LSM6DS3, with one side of the board featuring power and I2C functionality while the other side sporting pins that control SPI functionality and interrupt outputs. Please keep in mind that the LSM6DS3 is a 3.3V device so supplying voltages greater than ~3.6V can permanently damage the IC. A logic level shifter is required for any development platform operating at 5V.Features:Power consumption: 0.9 mA in combo normal mode and 1.25 mA in combo high-performance mode up to 1.6 kHz.Always on experience with low power consumption for both accelerometer and gyroscopeSmart FIFO up to 8 kbyte based on features set±2/±4/±8/±16 g full scale±125/±245/±500/±1000/±2000 dps full scaleAnalog supply voltage: 1.71 V to 3.6 VSPI/I2C serial interface with main processor data synchronization featureEmbedded temperature sensor
