5N30.95 - Sensor Wall
To demonstrate that you can detect different items using sensors that are located behind a wall. This includes electric fields, magnetic fields, heat, radioactivity, and density changes using radio frequencies.
Plug in the apparatus and make sure the switch is off. Be sure that the leads of the M are plugged in. Make sure the blank side of the board is facing the audience. Check that all of the sensors are working and that no batteries have died.
You can do any of the sensors in any order except the infrared camera part, we suggest you do last. Take the sensor bring it up to the board and move it around until it detects something. The only tricky one is the stud finder as any kind of density changes will set it off, the M will trigger the device. To do the IR camera portion, make sure the IR camera feed is visible to the audience. Then flip the switch on the board and wait approximately 45 seconds and the heat signature should begin to become visible on the IR camera.
This demo is used to show you how an experimentalist will take advantage of the available measurement equipment in order to get a better understanding of the environment they are studying.
IR Camera - Can pick up temperature differences of 4 mK or moreMagnetic Field Det - Can pick up the presence of a mag field and polarityElectric Field Det - Can detect the presence of electric fields generated from live wiresStud Finder - Uses radio waves to detect density variations, first start in a low density area, then move to higher density to show a positive readingGeiger Counter - Measures ionizing radiation through an "end-window" Geiger-Muller tube
