AI(r) Freshener

Remember in Back To The Future III,

Doc Brown built an elaborate device, so he can have Ice cubes for his drink?

This project is like that in a lot of ways. - a lot of technology for a really simple and stupid reason.

Using a bathroom air freshener is pricey with a 7oz can (of Lysol) costing $3.50 - $4.00 a can (while you can get the normal 19 oz can for $1.99) I didn't want it to be wasted on random timed room sprays and wanted more intelligence to only use when needed (and to stretch out the supply) [AKA why all the high tech mumbo jumbo]

Here is a very short video of it working

Ecobee smart sensor (you can use any occupation sensor you like, this is what I had 'lying around')

at $18 it wasn't a major investment, my only issue with it, is you need to buy the smaller (and much more expensive) cans of air freshener, I prefer the Lysol, and modified the sprayer to accommodate them.

Using the Broadlink app I created the two devices, the IR transmitter and a 'trigger' Button for the AI(r) freshener (yea, I love the name)

Using alexa routines, The rest is just programming the ecobee sensor to detect room occupancy, and then spray the freshener.
