Pollen sensor for hay fever alert
-
Not sure if any one has ever used/made a pollen sensor. So I thought I'd post the question anyway. Since a couple of years I have a light form of hay fever. Since I'm planning to build a variant on the solar powered weather station, I was thinking about adding a pollen sensor. But I don't know if there's one available for the Arduino.
So if anyone can help me with this quest, I'll be able to keep the windows open in the spring. And let my shutters go down when there to many pollen in the air. Any help is much appreciated.

Good pollen sensors are pretty expensive (I think).
Wouldn't it be easier to integrate your controller with some webservice to retrieve this information for your region?
Here in Sweden it's pretty common. Like this example:

@hek We think the same. I couls hookup NodeRed to an online service and post the values on Mosquitto. But if I can find a sensor that I think it's affordable. I'll build it myself. I also read somewhere, that a dust sensor can be used as a pollen sensor. Will investigate that a bit more.

and in Denmark you will use this:
http://www.dmi.dk/vejr/sundhedsvejr/pollen/And to be actually, the pollen is handcounted every day during the season - there different kinds of pollen in the air Bitch, Grass, Fungus, Well all kind of trees through something around... I don't believe for now there exist a cheap automated system for this...
The best/easiest you can do for your house, crate a hole in your walls and install a fan with filter and keep your windows shut. Something similar like the below link

I think even that they are manually read most pollen sensors... i saw in another thread about some new sensor but it was experimental i think. I also have a command in my controller reading a RSS and updates a id with a json command.

In two words - I do not think this is feasible or economically feasible as there are many types of pollen and one has to distinguish between particles and organic pollen.
I was looking for a similar sensor, but only managed to find this thread:http://forum.arduino.cc/index.php?topic=359052.0
From this thread:
I think that is not possible.
A nose can detect pollen long before any dust detector would.
To measure the pollen, pull air through a filter, and after 24 hours, investigate the filter in a laboratory.This is a patent : http://www.google.com/patents/US20040066513
The patent is about to distinguishing pollen from dust. Honestly, I doubt of that will work.Basically, you need to pay somewhat $2,200 for the PS2 Pollen sensor.

Looks as though the PS2 Pollen sensor may have been discontinued: https://www.tequipment.net/Kanomax/PS2-PS/Particle-Counter/
Even at $2,200, I haven't found the PS2 pollen sensor for sale anywhere. I went looking, thinking that surely by now the price would have dropped.I did find a particule sensor for sale that seems to imply it can also measure pollen: https://www.ebay.com/itm/Laser-Dust-Sensor-Module-DC-24V-Particle-Pollen-Mycete-Detection-Set-PM2-5/352422192333?hash=item520dffe4cd:g:TnEAAOSw65FbZL6V
How well it works or not I coudn't say, but it is a lot less expensive.

However, it does appear that TI has a design for measuring pollen using a photodiode: http://www.ti.com/lit/ug/tidub65c/tidub65c.pdf

Looking at it more closely, I noticed that TI's design is meant to is to attach directly to the optical chamber of the Sharp Microelectronics optical dust sensor (part number: GP2Y1010AU0F).
