Presentation Content Project Motivation and Goals Background – ESP8266 Chip Work Environments and Required Tools Project Top Block Diagram Home sensors Planned Webpage Project Schedule and Gantt Bibliography

Project Motivation Reduce the price of IoT devices for everyday consumer Learning about the chip abilities Creating specific solutions for smart house applications

Project Goals Creating low-cost Wi-Fi SoC that will monitor temperature, humidity and current consumption Produce product that costs 2$ (other products cost more then 10$ ) Creating user interface for controlling and monitoring the system (webpage) Access the system from all over the world

BACKGROUND – ESP8266 CHIP Built-in low-power 32-bit CPU ESP8266 is a complete and self-contained Wi-Fi network solutions 802.11 b/g/n Support 3 modes: AP, STA, AP+STA Built-in TCP / IP protocol stack Built-in low-power 32-bit CPU Standby power consumption of less than 1.0mW Main Serial Interface 2 General Purpose IO (on ESP12 up to 16 GPIO)

Work Environments and Required Tools To be able to program the module we will connect the module, using a USB-Serial cable, to the PC Initial environment - we will use a serial monitor (putty) and use the basic AT commands to talk to the module LUA programming language ESPlorer - Integrated Development Environment (IDE) for ESP8266 developers NodeMCU - A LUA based firmware for WiFi-soc ESP8266 HTML
