Story

What is Sonoff?

Sonoff Basic is an affordable device that provides users with smart home control. It is a WiFi-based wireless switch that can connect to a wide range of appliances. Sonoff transmits data to a cloud platform through the WiFi router, which enables users to remotely control all the connected appliances, via the mobile application.

What is ESP8266-01?

The ESP8266 ESP-01 is a Wi-Fi module that allows microcontrollers access to a Wi-Fi network. This module is a self-contained SOC (System On a Chip) that doesn’t necessarily need a microcontroller to manipulate inputs and outputs as you would normally do with an Arduino, it can save you some money and space in your projects.

Today we are going to show you how to making your own sonoff using esp8266 01 wifi module and relay. With this you can control your home appliances from anywhere in the world.

PCB:-

Therefore, case you want your own PCB, you can obtain through this link on PCBWay.com. You can also order good quality PCBS from PCBWay.com at low cost. In addition to the standard pcbs, we could also support advanced Pcbs, FPC/rigid -flex Pcbs, rapid-rpototyping and other related services that could meet your needs to the most extent.

PCB order steps on PCBWay:

Visit the website: www.pcbway.com
Click PCB Instant QuoteClickquick-order PCB Upload the gerber file by clicking "+Add Gerber File" and wait until the gerber file is finished
uploading Set the PCB specifications as you wish, starting from the number of PCBs, the number of layers, thickness, color and others.
After that, look at the left, it will display the estimated costprocessing time and delivery service selected

ASSEMBLING COMPONENTS ON PCB:-

1 / 2

Connect all components to the PCB

ESP-01 works at 3 volts, so LD33V IC is used to convert 5 volts to 3.3 volt.

SET UP ADAFRUIT MQTT:-

1 / 5

Adafruit IO is an IOT platform built around the Message Queue Telemetry Transport (MQTT) Protocol. MQTT is a lightweight protocol that allows multiple devices to connect to a shared server, called the MQTT Broker, and subscribe or write to user defined topics. When a device is subscribed to a topic, the broker will send it a notification whenever that topic changes. MQTT is best suited for applications with low data rates, strict power constraints, or slow Internet connections.

First you to create a free account for you on adafruit.io website.
Then by going to Dashboard you can go to ( Action ) and select " create new dashboard ".give it a name and click create.
Once you create your dashboard, go to " create new block "
Choose the type of block you want to use like toggle, slider
Create block

PROGRAMING ESP-01:-

1 / 9

I flash esp-01 using the Esp8266 Serial Module Board

Insert ESP-01 to USB serial module
Connect Esp8266 Serial Module Board to PC
Set up Wifi SSID, PASS, AIO USERNAME, AIO KEY & FEED NAME (The username and aio key can be found by clicking on "My Key" in the adafruit account, If you do not understand, watch this video(Click Here))
Go To Tools>Board>ESP8266 Boards> Generic ESP8266 Module (Adafruit_MQTT_Library must be installed)
Select Correct Port
Upload Code Below

1 / 3

After programming, set the ESP-01 module to PCB. With this our PCB work is completed...

INSTALL PCB ON CASE:-

1 / 6

I have made a case here using PVC sheet, Just do the case if you want

First, Insert PCB in to Case

Glue the bottom part using a piece of PVC sheet

Glue the bottom part using a piece of PVC sheet

Now all our work is completed....

CONNECTION:-

1 / 5

Connect 230v AC supply in to "IN" terminal
Connect Load in to "OUT" terminal

I use a led bulb for testing...

APP:-

1 / 3

An application called "IoT OnOff®" is used to control the relay..

Open the application and set MQTT Broker

Host = io.adafruit.com
Port = 1883
Username = Your Adafruit IO Username
Password = Your Adafruit IO Key

Then add switch & Set

Publish = Username /Feeds/Feed name
Publish Value = True=1, False=0
