Grove dust, temperature and humidity sensor, fan

[se.hematpour]

Hi
I am a PhD student in Uk trying to develop an air quality monitoring devdedesignedice,designed by another student.
I am quite new in this area.
The air quality device is using:

1. Raspberry pi zero
   2.Mikrobus ozone sensor( MQ135)
   3.Air quality click(MQ131)
2. Pi 3 click shield
3. Grove dust sensor
   6.temperature and humidity sensor( DHT22)
   7.RTC
4. Expanded board
   The student has soldered a prototype board to to connect Grove dust sensor and DHT22 to expanded board for raspberry pi zero.
   Now I am looking for more robust solution. Based on this topic:

GrovePi Zero and Dust Sensor

I am trying to use the Grove Dust sensor module with a GrovePi Zero. I am getting: Reading from the dust sensor 0 0 0 0 0 I have Tried A2 port and D3 port. Which port should I use?

1 .
I was wondering if I can use Grove pi plus + Grove temperature and humidity sensor ( instead of DHT22) for connecting them to expanded board.
2. As raspberry getting temperatured, is there any fan compatible with Grove pi plus?

Thanks in advance for your help.
