All in One Weather Station Using Eps8266(Nodemcu)
This project is about the creation of an indoor weather station with air quality sensors,humidity, temperature, CO2,sSO2,CO,Vibration and wind sensor
Create a DETAILED Schematic of What You Are Doing

This project is about the creation of an indoor/outdoor weather station with all the possible parameter measurement
The station has several sensors for:
- Humidity,Temperature (DHT22/11)
- MQ2 (Lpg,Propane,Alcohol)
- MQ135 (Air quality sensor -CO,SO2,CO2)
- Rain sensor
- Vibration sensor
- Wind flow sensor
The resulting data can be displayed various platforms like on a TFT screen,through an online dashboard or a Mobile app.
For the schematic i have used EasyEDA software
Select the Perfect Microcontroller for Your Project
NodeMCU is an open source firmware for which open source prototyping board designs are available. The name "NodeMCU" combines "node" and "MCU" (micro-controller unit). The term "NodeMCU" strictly speaking refers to the firmware rather than the associated development kits.
As i wanted a IOT platform integrated to my project,there is no other mcu(microcontroller) better than nodemcu(esp8266)
Select the Sensors for Weather Monitoring
In order to develop the project we will need the following components:
- NodeMCU ESP8266 microcontroller
- 16 channel analog Multiplexer
- LCD 16x2 I2C shield (optional as we will be using IOT Dashboard to monitor)
- MQ2
- MQ135
- DHT22
- Vibration sensor Wind sensor
Why Analog multiplexer?
It is very important for NodeMCU as it only has one Analog Pin, so for multiple sensors we require a analog multiplexer.
Designing the PCB
As we will using this as a complete module,we then require a PCB board.
I have designed this using easyEDA
Simulated 2D and 3D Design View
This is how our board will look!
PCB Order
I have ordered this PCB from
Soldering Time!!!!!
This is how a neat and structured soldering looks!
Very much similar to our simulated version :)
Modules Intact(sensors)
Add the modules accordingly!!
Working Time!!!!!!!!!!!
Yes its not any Star wars Shield, it is our board......pat yourself !
I have provided the code too:)

Dashboard (IOT)
For dashboard purpose i have used
