This document provides guidance on starting an IoT journey by outlining a basic IoT architecture and process. It discusses how IoT can help businesses by increasing efficiency and reducing costs through applications like predictive maintenance, traffic monitoring, and precision agriculture. A basic layered IoT architecture is described including data collection sensors and devices, edge communication gateways, centralized data processing in the cloud using analytics and machine learning, and applications. It also covers considerations for choosing wireless technologies, two-tier vs three-tier solutions, public vs private cloud, and basic security concerns. The overall process involves identifying business problems, choosing technologies, deploying solutions, and ongoing management.

- 9. Ok, what doesit take to start ? A simple IOT architecture, in a layered model 01 | Predictive maintenance, centralized policy Application Centralized Data processing Edge data processing and Communication Data collection and Control 02 | Public/private cloud, analytics and machine learning 03 | Local optimization OR direct transfer to cloud 04 | Sensor to read data, MCU to collect data and control actions
- 10. Data collection andactions What is the business problem you are solving ? ● Needs sensors to read the data you want to monitor ○ Power consumption, vibration, temperature, proximity, levels, gas.. ● Need to power off devices ? ○ Relays, pneumatic actuators, switches ● Sensors connect to gateways OR to a small processor or controller QUICK TIP Choose sensor of good quality, accuracy is very critical The sensors and actuators must last long, service cost can be high,
- 11. Edge Communication Brings in‘I’ of IOT ● Data collected must be transferred to centralized location ○ Centralized policy ○ Better decision with more data ● Host of solutions available ! ○ Gateway connecting via GSM ○ Gateway connects a local LAN and than to WAN
