Internet of Things GEE 13 – Living in the IT Era GEE 13 Living in the IT Era A Question Cast to TV! Open Netflix How does that work? GEE 13 Living in the IT Era  Interconnection Router Router (and other network devices) provides a medium for two (or more) devices to communicate through a network. In addition, electronic appliances and devices are programmed to receive signals through such medium and understand what GEE 13 the other wants to do. Living in the IT Era Components of IoT 1. Sensors and Modules 2. Microcontrollers 3. Connectivity GEE 13 Living in the IT Era Sensors and Modules Provides the ability for a device to recognize its surroundings and receive / send signals from one component to another. Temperature & Humidity Smoke Detection Proximity GEE 13 Living in the IT Era Temperature & Humidity Sensors Temperature sensors gather data about how hot or cold something is. This something could be the surroundings, an object, or a person. Humidity sensors determine how much water vapor is present in the air. Such sensors are heavily utilized in health and medical sectors, factories, and other environments where temperature and humidity is a critical factor to the overall integrity of a job or service. GEE 13 Living in the IT Era Proximity Sensors Determines how close an object is relative to a point of view. Used in cars, especially in very modern cars. GEE 13 Living in the IT Era Smoke Sensors Detects smoke and alerts people and / or nearby electronic appliance when smoke is detected. GEE 13 Living in the IT Era Smoke Sensors GEE 13 Living in the IT Era Other Types of Sensors GSM Module sensors that provides wireless Global System for Mobile communication through cellular networks. Used for Communications sending SMS messages, phone calls, or mobile data connections Uses ultrasonic waves that calculates precise distance measurement without physical contact. Ultrasonic Distance Sensor Utilized in navigation, robotics, and obstacle detection. Commonly used in modern smartphones where the Luminosity Sensor screen automatically adjusts brightness based on light intensity noticed by the sensor. GEE 13 Living in the IT Era Other Types of Sensors Similar to Ultrasonic Distance Sensor but instead, utilizes the infrared frequency to detect movement. Passive Infrared Motion Sensor This is ideally used by security cameras, automatic lighting, and occupancy detection. Detects the presence of various gases such as methane, propane, and carbon monoxide, which is Gas Sensor proven to be helpful for detecting potentially hazardous gas in the working environment, and also, pollution. Measures the moisture content present in the soil Soil Moisture Sensor which is useful for farming and possibly, building construction. GEE 13 Living in the IT Era Other Types of Sensors Empowers microcontrollers to allow them network / Wi-Fi Module Internet connectivity, enabling communication with other devices on the same network or remotely. Provides a different wireless communication medium between devices, enabling wireless data Bluetooth Module transfer and serial communication with other devices with a Bluetooth Module installed. Combination of accelerometer and gyroscope for Accelerometer and Gyroscope precise motion sensing and tracking for gesture Module recognition, orientation tracking, and stabilization in robotics. Radio Frequence Identification communication, RFID Module enabling reading of RFID cards or tags. GEE 13 Living in the IT Era Microcontrollers Provides functionality to the sensors, where microcontrollers are programmed to control the behavior of sensors when exposed to various conditions. Furthermore, at least one sensor can be connected to one controller. GEE 13 Living in the IT Era  Common Microcontrollers Arduino Raspberry Pi Beginner Deep and close to Has better Complex Projects Simple Projects hardware hardware (Send data from (Switch lights on/off) specifications cloud/server) GEE 13 Living in the IT Era Connectivity Microcontrollers and sensors must be connected to some network (in most cases, the Internet), to communicate with other devices and process the data into information understandable by their users. GEE 13 Living in the IT Era User and their computer (cellphone in this case) GEE 13 Living in the IT Era  Lightbulbs with microcontroller (with installed sensors such as timeclocks for timer and other time-based functionalities) GEE 13 Living in the IT Era Router connecting microcontroller and cellphone GEE 13 Living in the IT Era  Hey, turn on! SWITCH LIGHTS ON! GEE 13 Living in the IT Era Examples of IoT Internet of Things GEE 13 Living in the IT Era  Smart Self Driving Car (Waymo) A self-driving car equipped with GPS, Wi-Fi, and various sensors such as proximity sensors. It can transport passengers from point A to point B without the need of a human driver. GEE 13 Living in the IT Era Image retrieved from: https://waymo.com/intl/fil/media-resources/  Amazon Echo Dot A voice-assistant device that can listen to voice commands such as playing music, request Uber driver, online shopping order, calendar reminders, etc. It is hands-free, meaning users does not need to press some button to operate the device. GEE 13 Image retrieved from: https://jgsuperstore.com/products/amazon-echo-dot-4th-gen-smart-speaker- Living in the IT Era with-alexa-juan-gadget  Smart Plugs Plugs that can be inserted into existing outlets, and then where appliances can connect to such smart plugs. Doing so provides the capability to control the plugged appliance(s) on or off remotely either through commands or using a timer. GEE 13 Image retrieved from: https://www.toolstation.com/tp-link-tapo-p100-smart-plug/p59000 Living in the IT Era  Smart Bulbs Light bulbs where one can control what color should it light up. With the assistance of additional sensors, it may be able to automatically adjust the lighting based on time, mood, and whether you are sleeping, exercising, watching movies, and other activities. GEE 13 Living in the IT Era Image retrieved from: https://onetech.ph/products/smart-bulb  Smart Thermostats Provides the capability to automatically adjust temperature based on your requirements. Other than that, one may also configure how warm or cold it should be based on the time.
