Garage Door Monitor (ESP8266 CPU)

thingiverse

The Smart Garage Door Watcher continuously watches whether your garage door is closed and sends out an email or text message right away if it's been left open for more than 15 minutes. It uses the popular ESP8266 WiFi module to send messages directly to you via the IFTTT web service. In our household, we've accidentally left the garage door open multiple times, and this device has saved us more than once. The source code and detailed assembly instructions can be found on my GitHub website: https://github.com/elkayem/SmartGarageDoorWatcher Features: * Email and/or text sent every 15 minutes when your door is left open, notifying you exactly what time it was opened and how long * Email/text sent once your door has been closed * Synchronization with NIST time ensures accurate monitoring * Enable/disable button can temporarily disable the monitor as needed * RGB LED indicates monitor status in real-time * (Optional) logging of door status via Adafruit IO for added convenience * (Optional) OLED Display adds an extra layer of functionality To build this project, you'll need the following parts, as pictured below: * NodeMCU V1.0 development board (also listed as v2 at online shops like eBay or AliExpress) * Normally Open magnetic switch * Two Female headers * Common Anode RGB LED * Screw Terminal Block (two-pin 3.5mm Pitch) * Six-by-six millimeter tactile button * Three 300-Ohm resistors * (Optional) four-pin male header * (Optional) Printed Circuit Board (see GitHub site for Eagle files) * (Optional) 128x64 I2C OLED Display (preferably a two-color display, like yellow/blue) The PCB is optional since the circuit is simple enough to hand-solder on a breadboard if desired. An OLED display can enhance the monitor but isn't necessary.
