26 Infra Red Infrared Proximity Sensor Photo Interrupter Infrared Emitters and Detectors Description: Infrared proximity sensor made by Sharp. Part # GP2Y0A21YK has an analog output that varies from 3.1V at 10cm to 0.4V at 80cm. The sensor has a Japanese Solderless Terminal (JST) Connector. We recommend purchasing the related pigtail below or soldering wires directly to the back of the module. Description: This sensor is composed of an infrared emitter on one upright and a shielded infrared detector on the other. By emitting a beam of infrared light from one upright to the other, the sensor can detect when an object passes between the uprights, breaking the beam. Used for many applications including optical limit switches, pellet dispensing, general object detection, etc. Gap width = 10mm INST. Kerem Odabaşı - YTU - Interactive Telecomunication Design Dept.

27 Proximity Ultrasonic Range Finder Features: 42kHz Ultrasonic sensor Operates from V Low 2mA supply current 20Hz reading rate RS232 Serial Output bps Analog Output - 10mV/inch PWM Output - 147uS/inch Small, light weight module Red wire is power (5 to 12V). Brown wire is GND. Black wire is open collector Alarm.This unit works great from 5 to 12V (datasheet shows 12V). You can also install a jumper wire past the 5V regulator on board to make this unit work at 3.3V. Sensor uses PIR Motion Sensor ePIR Features: fully functional motion detection based motion detection algorithms VDC operating voltage Typical current draw: 8.9mA Wide 5 x 5m, 60 degree detection pattern Simple hardware or advanced serial Adjustable sensitivity, delay and ambient light threshold INST. Kerem Odabaşı - YTU - Interactive Telecomunication Design Dept.

28 Magnetic Hall Effect Sensor Description: 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 encapsulation and size. A hall effect sensor is much smaller, but can handle less current than a reed switch. Features: Simple I2C interface 2.7 to 5.2V supply range 1 to 20Hz selectable update rate True drop-in solution 0.5 degree heading resolution 1 degree repeatability Supply current : 3V Compass Module INST. Kerem Odabaşı - YTU - Interactive Telecomunication Design Dept. Description: PNI Corp's 3-axis magnetometer. Ready for the big time? Low noise, large resolution magnetic field sensing all packed into a user-friendly DIP module at your disposal. Stable over a wide temperature range, the MicroMag3 is a must have for orientation sensing and navigation.PNI Corp's Features: 3.3V DC Field measurement range +/-1100uT Resolution as low as 0.015uT SPI interface - no additional circuitry needed 3-Axis Magnetometer

29 Temperature Digital Temperature Sensor Description: This is a breakout board for the incredibly small TMP102 digital temperature sensor. The TMP102 is a digital sensor (I2C a.k.a. TWI), has a resolution of °C, and is accurate up to 0.5°C. The sensor requires very low-current, and is loaded with features. Description: Melexis' MLX90614ESF- BAA is an infrared thermometer designed for non-contact temperature sensing. An internal 17-bit ADC and a powerful DSP contribute to the MLX90614's high accuracy and resolution. It has a huge number of applications including body temperature measurment and movement detection. Infrared Thermometer INST. Kerem Odabaşı - YTU - Interactive Telecomunication Design Dept. Thermistor 10K Description: 10K thermistor with a negative temperature coefficient. Good choice for temp- sensing aplications.

30 Weather Humidity Sensor Description: This is a breakout board for Honeywell's HIH-4030 humidity sensor. The HIH-4030 measures relative humidity (%RH) and delivers it as an analog output voltage. You can connect the output of the sensor directly to an ADC on a microcontroller; and, thanks to the sensor's near linear voltage output, the data is very easy to process. Barometric Pressure Sensor Description: The SCP1000-D01 is a great IC - now you can play with it! This is a simple breakout board bringing the SPI interface pins to a 0.1" header. Please note, we now stock the latest ASIC rev C (IC label 'D01'). The SCP1000 is the very first absolute pressure sensor on the market to use MEMS technology to grant 17-bit resolution. Under ideal conditions, this sensor can detect the pressure difference within a 9cm column of air. INST. Kerem Odabaşı - YTU - Interactive Telecomunication Design Dept. Weather Meters Description: This is a simple weather station that includes an anemometer, wind vane, and rain gauge. Includes mounting hardware and RJ11 connections to the sensors. The anemometer uses a reed switch, so simple frequency detection can be used to measure wind speed. The wind vane uses a potentiometer to detect wind direction. The rain gauge acts as a switch that closes at measured increments. Please see the datasheet for more information.

31 Biometrics Alcohol Gas Sensor Description: 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, all it needs is one resistor. A simple interface could be a 0-3.3V ADC. Fingerprint Scanner Description: The Nitgen RS232 serial fingerprint scanner is a powerful ADSP- BF531 Blackfin based system. 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. Polar Heart Rate Module Description: This is a OEM module for the Polar Heart Rate system. This device works with any Polar heart rate strap to pickup the electromagnetic pulse and output a 1ms pulse indicating a heart beat has occurred. Embed a heart ratereading into your next project!heart rate INST. Kerem Odabaşı - YTU - Interactive Telecomunication Design Dept.
