Sensors

–Wikipedia A sensor is a device that detects events or changes in quantities and provides a corresponding output, generally as an electrical or optical signal; for example, a thermocouple converts temperature to an output voltage.

Use Cases

Detect : Anticipate : React

Detect : Anticipate : React Detect behavior. Anticipate behavior. React to behavior.

Hotel Room Monitoring and Automation • Why heat/cool an unoccupied room? • Detect occupancy. • Anticipate occupancy. • React to occupancy.! • Added benefits to customer experience. • Analyze customer behavior.

Quikie Auto Lube • Manage inventory in response to demand. • Detect inventory. • Anticipate customer demand. • React accordingly.

Hospital Infection Control • CDC: Hospital acquired infections cost $30B per year and lead to 100K patient deaths. • Inadequate hand washing a big cause.

Hospital Infection Control • Ensure proper hygiene of medical staff • Detect staff presence. • Anticipate hand washing. • React to inadequate hygiene.

Hospital Infection Control

Auto Insurance • Rethinking traditional risk assessment • Detect unsafe driving practices. • Anticipate who is most at risk. • React to risk assessment.

Use your imagination.

How can you use and combine sensors to better serve your [user’s] needs?

What is Arduino?

What is Arduino? • Open Source Microcontroller Hardware + Software • Geared toward prototyping • “Physical Computing:” interacting with the environment "Arduino is an open-source electronics platform based on easy-to-use hardware and software. It's intended for anyone making interactive projects.”

http://adafruit.com

What is Arduino?

Programming Arduino • Official cross-platform IDE written in java • C/C++ with some sugar • Program referred to as “Sketch” • Many open source libraries available for various hardware (sensors, etc.)

Going Wireless with XBee

What is XBee? • Radio modules that support wireless point-to-point communication • Serial communication • Minimal connections required — power, ground, data in, data out (UART) • 2 power options (1 mW/100 mW) • Support for multiple network topologies (Mesh, star, tree, etc.)

Arduino Esplora Several sensors included. (no soldering required)

The Dog Ate My Demo! Okay, he just chewed part of it. But all is not lost…

Arduino Sketch (Sensor) #include ! #include ! ! void setup() {! // initialize the serial communication:! Serial.begin(9600);! }! ! void loop() {! // read sensor variables! int loudness = Esplora.readMicrophone();! int light = Esplora.readLightSensor();! int temp = Esplora.readTemperature(DEGREES_F);! int slider = Esplora.readSlider();! int joystickButton = Esplora.readJoystickSwitch();! int xAxis = Esplora.readAccelerometer(X_AXIS);! // … ! ! Serial.print("{");! // Misc. Sensors! printAttribute("temperature", temp, false);! printAttribute("loudness", loudness, false);! // …! Serial.println(“}");! ! delay(1000); ! }! ! Initialize serial communication Read sensor values Dump JSON to serial port (XBee) Include Esplora convenience lib

Serial Monitor (Collector) • Read serial data, parse JSON • Add timestamp • Add device/sensor UID (“Sector 7-G”) • Publish to Kafka
