ScannerPal M-Switch Event Sensor

Interfaces any kind of mechanical or electronic switch to an iDEN Java application. An ASCII serial port character is sent to the application which will uniquely indicate each make or break of the switch.  (Debounce is built-in.)  The Java app can do anything it wishes with each event in real time, such as simply recording it, and/or transmitting events wirelessly to a web host.

The different ways that the M-Switch can be used are limited only by imagination.

 Example usages include:

• Passenger gates.
• Vehicle passenger counting.
• Conveyer belt product counting and timing.
• Bin monitoring, as with parts bins or brochure racks.
• Security alarm switches on windows, doors.
• Motion detection.
• Traffic counters.

Examples of the types of switches that can be intefaced to an M-Switch:

Available from ScannerPal:

• Step pads.
• Infrared and laser "break beams".
• IR and sonic proximity and motion sensors.
• Door and window switches, mechanical and magnetic.

The M-Switch will work with any sort of electrical switch: momentary, SPST, reed, relay, N/O, N/C, etc. So if you have your own switch design, it can be used as well. It can simply be an open/closed ground of the provided 5v signal source, or if more convenient, an open/closed signal injection of 3-24v.  For example:

• Ordinary doorbell pushbuttons.
• Light/dark switches.
• Timers.
• Photocell output.
• TTL from a microcontroller or discrete logic circuit.
