The age of Star Trek continues to mature. Here are a few interesting additions to an I phone that will collect various data inputs. Keep in mind, I do not own these items and that I use this a more of a note taking location for myself then to promote any product.
Scio This company has an interesting tool that reads the spectrum light from an Item. There is a Database of chemical makeups that can be referenced to identify what you are looking at. It can also tell you some nutritional information of your foods. It may not know everything yet but the database of items is continuing as more people us the meters and share the information they collect. I have not used this item but would love to try it, I think there could be a lot to learn from a device such as this.
Lapka This company has an interesting product, it is really a group of individual sensors that can store together. I like the mix of sensors but I am not big on the fact that there are individual parts. I have known about this product a few years so maybe in the not to distant future a smaller single device could come to market.
Supermechanical Now I like to cook and have been looking for a temperature probe to provide accurate measurements when cooking, baking, canning, and I want to try making my own candy too. I hope to pick this up sometime soon, if and when I do Ill change this to reflect what I learn and think of the product.
FLIR Now this I wish was just built right into the phone. It is a near Infrared camera that sees heat. the nice thing about this is that it is a case and battery pack as well. A little pricy but interesting.
Node This is a modular group of sensors. there is the base and various sensors can be individually used. This unit is more industrial then the lapka and does different functions great idea but still not an all in one solution to collecting data on your environment.
