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

• The chip
integration with
variety of smart
house sensors can
bring unlimited
possibilities
• Reducing the
system price would
make the smart
house dream more
accessible
