From connected cars to connected wearables to home security, the Internet of Things is rapidly marking its presence in every field. Now we have IoT enabled home automation and security devices that can be controlled from anywhere in the world using the Internet of Things. There are many kinds of Wi-Fi door lock available in the market which makes your home more secure and saves time in finding the keys. Here we are also building a similar Wi-Fi door lock which can be controlled from the Smartphone.
Here NodeMCU will act as the main controller and connect the user to the door lock system using the Internet. In conventional door lock, there is key to pull or push the latch, and we have to operate it manually, but in solenoid lock, the latch can be operated automatically by applying a voltage.
Solenoid lock has a low-voltage solenoid that pulls the latch back into the door when an interrupt Pushbutton, Relay, etc. The latch will retain its position until the interrupt is enabled. The operating voltage for the solenoid lock is 12V.
Door Status Monitor using the ESP8266
You can also use 9V, but it results in slower operation. Solenoid door locks are mainly used in remote areas to automate operations without involving any human effort. The circuit diagram for the Wi-Fi door lock is given below. I have soldered all the components on Perfboard as shown in the below pictures:. This is how the complete setup of wifi door lock will look after installing on the door:. Using Adafruit IO, you can upload, display, and monitor your data over the internet, and make your project IoT enabled.
For test and try, with some limitation, Adafruit IO is free to use. Copy this key and username, it will be needed later in the code. Now, after this, you need to create a feed. After this, a new window will open to enter the Name and Description of the feed. The writing description is optional. For that, first, create a dashboard and then add your feed in this dashboard.
As the dashboard is created, now, we will add our feeds to the dashboard. Here we will add a toggle button blocks to turn open and close the Wi-Fi door lock.You can make apps work together.
A new page loads when you finish connecting your Gmail. You should see something similar to the preceding Figure. You can use the preceding links or go directly to MakerAdvisor. The schematics to upload code to your ESP are very straight forward. Copy the sketch below to your Arduino IDE.

Hardware design. Basic of Deepsleep.
Deep sleep mode of chip stop un-necessary processes when it not required. Like when we mention delay command in the code it mean controller is awake and doing process to execute it but how can we do without consuming more power. ESP chip provides 3 configurable sleep modes. We can choose and configure the sleep mode as required. The 3 sleep modes are:.

In this mode, the chip will turn off Wi-Fi connectivity and data connection; only the RTC module is still working, responsible for periodic wake-ups. You need to connect D0 pin Ping number 16 to reset, so whenever you counter reach out deepsleep time, it will enable a reset. Meaning it will reset a chip and code will work in normal mode.Add the following snippet to your HTML:.
