Room Control With ESP8266 | Temperature, Motion, Curtains and Lighting

This project consist on a system based on the NodeMCU ESP8266 module that let you control the brightness of a LED Strip and the curtain of your room, also it's able to send data about the motion events of your room and the temperature to the cloud where you can see it by Ubidots IoT platform.

PCB Design (Gerber):

Here is the Gerber File so you can order your own PCB.

I suggest to use PCBGOGO to manufature the PCBs.

Soldering Everything:

Clean up the circuit pads if they are not and start soldering everything step by step.

Install the Libraries for the Code:

Here is the link where to can download the libraries.

Upload the Code:

Order of Images:

1-When the NodeMCU is turned on, automaticaly it will create a device called "room" in the devices section of Ubidots.

2- The device will have all the variables inside.

3- Go to Data/Dashboards.

4- Click on "+" to create a new dashboard.

5- Click on Check mark.

6- Create a Widget by clicking on "+".

7- Select Slider widget for the Curtains control.

8- Add a variable.

9- Select "Room" device.

10- Select "Curtain" variable.

11- Set step to 100.

12- Repeat for LED Strip but Step = 1 and Variable is "Ledstrip".

13- Add a indicator widget.

14- Select Movement variable.

15- You are done.
