The Stamp itself comes in several versions and form factors. The most common version is a module that plugs into a development board. So you can buy a Stamp module, or a development board, or both, depending on your needs. The development boards that use the Stamp modules allow you to use one of several different modules, depending on your requirements. There are also some boards available that use an integrated, non-modular Stamp.
The best analogy is probably the relationship to a PC CPU and a PC motherboard. There are several varieties and combinations available, depending on your goals.
Item 1 will give you the "brains"; Item 2 will give you the sensor; Item 3 will give you a project board that will enable you to easily connect the sensor to the brains and the brains to your computer.
You can do it less expensively, but this combination will enable you to easily do other projects as well.
