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

• 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
