Inventing Security Add‐on Kit
Product ID: 32002
Overview
The Security Add‐On Kit provides students competing in the Henry Ford Invention
Convention Worldwide the components to create a project using motion detection,
human identification and access control. This kit requires the Electronics Base Kit and is
ideal for grades 6‐8 and 9‐12 categories.
What kind of processes are used in security applications? People can be detected
moving in a 30‐foot area with the PIR sensor. They may be counted or detected at close
range with the laser rangefinder. Sometimes, objects may not be detected by their heat
signature or physical presence, but by the fact they create a noise. By combining
different sensing abilities people may be detected and even counted — and the Security
Add‐On Kit includes sensors for these kinds of processes.
RFID is used for identification and access control. The Security Add‐On Kit includes an
RFID Reader and 10 unique RFID cards. Cards may be carried by humans or attached to
objects. Add in the 4x4 matrix keypad and the person could be prompted to provide an
access code that matches their RFID card.
The programming environment for the Invention Kit Series is BlocklyProp. BlocklyProp is
a well‐documented visual programming language based on Google’s open‐source
Blockly. After using the Electronics Base Kit with the Security Add‐On Kit students will
have the ability to envision new solutions using a wide variety of sensors and devices
supported in BlocklyProp simply by looking at the BlocklyProp Reference.
Features
RFID Card Reader and 10 tags which may be attached to objects or humans to identify
themselves and compared to a list of acceptable ID numbers
Laser rangefinder, passive infrared (PIR) sensor and sound level sensor for detecting the
presence or quantity of objects or humans passing by a point
4x4 matrix keypad for providing a human interface and access control
Application Ideas
Pass control devices with lockbox and RFID
Doggy‐door pet access control to allow only authorized animals to enter the home
High‐value asset tracking (museums) with RFID tags
Beam‐break room alarms
Airport baggage tracking and claim system
