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).
