Baffled by the lack of information about sensors on the wiki? Do you find the information on the wiki hard to follow?
WELCOME TO YOUR CLASSROOM IN A BOX!

This is a tutorial for beginner and advanced scripters alike.Sensors are a powerful tool, though they are one of the most commonly misused functions in SL because of people trying to detect AVs and objects in incorrect ways, thus causing lag on sims.
This tutorial will help you decide if AND WHEN a sensor would be a good idea, and how to properly use them.
You will probably not find a lot of the information in this tutorial anywhere else - a lot of the past resources for this information are no longer available As well - new functions such as experiences have been added to SL which greatly effects the sensor function.

OBJECT-An interactive working VISUAL example showing exactly how sensors work
SCRIPT - A sample script to help you get started scripting your own efficient sensors.
NOTECARD - A full explanation about sensors how they work and the parts to scripting them properly
(notecard is given by "llSensor Example Object" when rezzed)

-Find out what determines who is detected, how its filtered and in what order.
-Find out how to use the filters associated with sensors
