I have been working on a project over the last month for my kitchen - a smart range hood. The plan is to use a RaspberryPi, four MQ air quality sensors, DHT22, and a GridEye infrared 8x8 pixel temperature sensor. I have the blog lost here: (full disclosure this is part of a contest; I just wanted to share it here since this is a group of like minded people. If this doesn’t belong PM me and I’ll take it down)
I plan to use the humidity sensor to turn the fan ON at something like 80% and rising and back off around 70% and falling (for histeresis). The air sensors are Methane, Hydrogen, Carbon Monoxide, and Propane. It will turn the fan on if any of these gasses get above safe levels.
I am using the PiCamera to take images of the Stovetop so my wife can text me when dinner is ready with a picture
The GridEye sensor will be used as an on/off sensor to see if any burners are on when we leave the house (using Owntracks geofence). I think I can detect the oven itself from the GridEye as well since it would make the entire field of view look warm.
What do you guys think? Any ideas I should include?
