Configuring arduino uno and esp8266 (air pollution monitoring project)

Development Tools Cloud IoT
1

Hello, this is my first time experimenting with a wifi module, I don't fully understand how to connect the serial communication between arduino uno and esp8266..
Here's my project:
I have 4 sensors (MQ131, MiCS-6814, PMS5003, DHT11), I'm measuring all of these with the Arduino uno, I want to transmit the data to the Arduino IoT cloud using ESP8266..
So I just wanna understand the principles and how I can go about doing that.

Here's my circuit connection of the sensors with the uno:

Basically what I wanna know is how can I implement the esp8266 to transmit the sensors' data to Arduino IoT cloud.

Hi rihamk,

You should start off by reading the following documents :wink: :+1:

Then lose the Arduino UNO & connect all the sensors directly to the ESP8266.
I also wouldn't recommend using a DHT11 as they are not very accurate!
You are far better off using a BME280, BME680, or even a BME688

HTH?

Nice. I also have a history which make me laughing sometime.

I have 2 analog sensors though, how can I use them on the esp?

Use an ESP 32
