IOT Smart Plug with Huzzah ESP8266
This MBED based project reads in power values from devices connected to the plug and gives the user the ability to turn the plug on and off using an internet based interface. The smart plug reads in power data from the ACS712 current sensor connected to a started 120VAC plug and sends the data to an mbed and a Huzzah ESP8266 wifi board. The mbed LPC1768 sends commands to the Huzzah ESP8266 to create a server and display an on/off toggle switch and the power data.
