Hi guys I was wondering if you could help me with a question I have.
I am looking to create an indoor 'environment' monitor that monitors all sorts of conditions in the room such as temperature and humidity but also dust particles and pollen to monitor allergies.
So I have think I have decided on this sensor to monitor dust: https://www.sparkfun.com/products/9689
As it does require a resistor to heat up in order to detect the dust particles which is an advantage over it's competitors.
I am struggling to find a sensor though that detects pollen. Any suggestions would be helpful. :)
Although as I was reading around I thought I read somewhere (can't seem to find it again) that either this dust sensor or similar ones also sense pollen. This is because they sense particles in the air and both dust and pollen are particles.
I'm not sure how to distinguish whether this sensor is sensing dust or sensing pollen. I'm not sure if it was this sensor or a different one that can tell the size of the particle and this is how is knows whether is is a pollen or a dust particle. I do believe it was the one linked above though.
I would like this project to be able to know levels of both pollen and dust.
So in summary: Does anyone know a sensor that detects pollen? Does anyone know whether the above sensor also senses pollen? If so how can you distinguish between dust and pollen
Thanks in advance
