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

4. 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

5. BACKGROUND – ESP8266 CHIP Built-in low-power 32-bit CPU
ESP8266 is a complete and self-contained Wi-Fi network solutions
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)

6. 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
