Research Notes 1

These are my initial research notes on both the cigarette smoke sensor that has an application to hotel rooms and on the smell detector targeted for men who want to smell good.

In order to create either of these projects I need to do some research on which sensors I can use with my Arduino Uno board. I will need an analog input sensor that detects smell or smoke. There are multiple MQ sensors that detect different types of gasses but there are no smell sensors that are compatible with the Arduino.
