Weather Station (evolution)

 If I can free more space in the box that contains all the components of the weather station: welcome!

I can do it using a component which contains a lot of sensors in itself. the BME280.

This electronic component is a multisensor, it can measure:

• Temperature
• Humidity
• Atmosferic pressure

BME280

 

I bought it here:

  That's all... then... start again projecting a new device!

Weather Station v2

 The second version of my weather station is almost done.

The following picture is a preview, enjoy!

 

Obviously, it is only a draft (you can notice the presence of notes on it). Moreover, a lot of tests must be done.

It's a little satisfaction have reached this further step...
 

Weather Station improvement

In these days, I though about the possibility to add another sensor to my personal weather station: the UV sensor: more useful for human skin especially in areas where I actually live (South-Italy: sunny most of the year).

Further specifications can be found at the following link:

Weather Station Update

Here it is!
Yep, it's my personal weather station which is working up on my balcony in Lecce!

You can note the presence of the polystyrene cover as a thermal insulator.

Some results...

Improving my station

I've been thinking about this particular improving for my weather station for a long time.
Adding an air pollution sensor!
Yep.
In this way I could have these sensors:

1. Temperature
2. Relative Humidity
3. Dew Point
4. Pressure
5. Air Quality measurement
6. Wind Speed
7. Wind Direction
8. Rain Rate
9. Light (on/off)

Last five points needed to be planned to be added to the actual station.

Restarting from the these last points we can divide them into groups based on their feasibility, giving a high score (5) to a thing that I can realise immediately and a low score to the thing that I have to realise with difficult and so for the last:

5 > Air Quality measurement

4 > Light (on/off)

3 > Rain Rate

2 > Wind Power

1 > Wind Direction

For the first point the difficult consist of find the way to connect the PPD42NS to my the pre-existing electronic card because if I want to interface the PPD42Ns to my card I need 5V of electric power supply. The ESP8266 can supply only a 3.3V tension.

I found out two ways:

1. using a converter to raise the tension from 3.3V to 5V. It would be arrived these days the card: 3.3V 5V TTL Bi-directional Logic Level Converter 2 Channel 2 Way IIC I2C LLC
2. using ESPertino card (like an Arduino provided with a wireless chip).

Thingspeak and my weather station

Once I have built the minimal structure of my weather station I decided it was important to become public the datas on the web in a way I could read it everytime I could. 

The name of the solution is ThingSpeak: on this page I can create my personal channel on which I can connect my ESP8266 via Wi-Fi and visualize, through linear graphics, various informations like temperature, pressure, humidity (and also a map with the point where the station is).

Here it is the graphic about the atmospheric pressure (updated in real time!)
