PM_Sensor_Kit_Code.ino where is it???

I am a teacher, and have been trying to find PM_Sensor_Kit_Code.ino to upload to my Arduinos. Where can I find PM_Sensor_Kit_Code.ino?

I found a copy using Google...

I have copy and pasted it into Google, and found nothing but instructions on a couple of websites (which I have tried). What did you do differently?

First result:

Second result is a pdf containing the instructions on setting up the kit.

I have downloaded Arduino on my computer, but cannot find the PM sensor Kit code anywhere on my computer or online. Any ideas?

I just gave you the link....

Open the page, select all the code, copy, then paste into your Arduino IDE window.

Then save.

Awesome and thanks!!!
