A panic button that sends emails, based on ESP-8266

I built a simple circuit based on an ESP-8266 module, the famous ESP-01. When I push the button, the circuit gets waken up and sends a preconfigured Email to preset recipients. After sending the Email, the circuit goes to deep sleep to preserve power. The circuit has very small physical footprint and power appetite -- with only 20uA in deep sleep mode, a regular house-hold battery can power it for months easily. Oh, and it's just under $1. My original plan for the circuit is for building an emergency help button for my mom. 


And, I probably said esp6288 instead of esp8266 in the video.
