IoTECH - Problem Statement & Recap
● “Smart Hub” - IoT Device
● Interface with OBD-II Port & External Sensors
● 3G/WiFi/Bluetooth data transfer
● Many potential applications
Problem:Most current IoT devices don’t extend beyond the home with WiFi applications. Very few automotive IoT devices on the market!

IoT Application: TempAlert
What does it do?
● Sense temperature and motion
● If threshold reached and motion detected, send alert via 3G to server (IFTTT) to user
What’s “In-the-box”?
● PIR Motion Sensor
● Infrared Camera
● Temperature Sensor (OBD & Dedicated)
● Particle Electron (3G)
● Particle Photon
● Bluetooth
