Methods of Motion Detection
In
this section I am going to show you four different ways of detecting
motion for use as a prop trigger. Two of them are hacks of existing
motion sensors, one (X10) is a wireless solution, and the last is an
electronics solution based on the parallax motion sensor and a
microcontroller or prop controller such as a prop1. All have advantages
and disadvantages depending on the prop, the on time required for the
trigger, and the amount of time before the prop can be triggered again.
Among these four methods you should be able to satisfy the requirement
of almost any prop. The four options are as follows:
The floodlight Motion sensor:
Advantages
Easy to use
Fairly inexpensive
Disadvantages
The least amount of control
Only a few reset time options

The Wall Switch Motion Sensor
Advantages
Easy to use
Fairly inexpensive
Adustable on time from 15 seconds to 15 minutes
Disadvantages
Indoor use only (must protect if using outside)

The X10 Wireless motion sensor
Advantages
Wireless
small sensor
good range
Disadvantages
Most expensive option
avarage on time delay options

The Parallax Motion Sensor
Advantages
The most configurable
Smallest sensor
The most adaptable
Can control multiple props
Can be sequenced (mini show controller)
Programmable in basic (Picaxe, Basic Stamp, Prop 1)
Disadvantages
At least basic electronics knowledge required (in links on the main page is a free online electronics course)
Must learn basic (for some microcontrollers)
Some circuits need to be made
If new to electronics small to moderate start up cost (some things you may already have)
