Project Description:

Looking for an engineer to design and build a proto of a long range Transmitter and receiver.

Range: ~800 meters- Must be designed so that I do not need a FCC license...

Transmitter--
size: flexible on size ( no larger than 8"x4"x6, but size is fliexibel)
Power source- needs to be able to plug into home 110V AC
Function-
-----Transmitter will detect a switch being open or closed (on or off) via a push button switch type device.
-----Once the state of the switch is detected it will transmit the status to a receiver
----- When the transmitter senses the "switch" status change thats when it will transmit the status

Receiver--
Size : must be small- ~ 4"x2"x1"
Power source-- needs to function off of Battery or 12V DC or both.
Run time off battery needs to be at least 1 month-
function-
------ Rx will get a signal from Tx to show status of open or closed switch ( on or off)
------ When Rx get a open signal (on) from Tx it will power up a Green LED
------ When Rx gets a Closed signal (off) from Tx it will power up Red LED
------ Once LED will stay on for 45-60seconds
------ When user wants to know the last known state of the LED they can push a button that will power up the LED RED or GREEN depending on the last state the LED was in.
------ LED will be a dual or tri color LED--- one LED for all uses--- This LED does not have to be mount on board- It can be a remote lead--- about 5'
------ Button (switch for user to press to find out last state of LED) will also be remote mounted and does not need to be on the PCB.

i will need 8 prototypes made

This is a perfect application for the PIC-BEE and a XBee-PRO module. The PIC-BEE is being replaced with an updated model the PIC-BEE2, but has much the same feature sets plus now having an integrated boost power supply such that it can run off two AA batteries. It can also be mounted in wireless enclosure from NewAge. The website, www.pic-bee.com does not yet show the new models, but I can provide pictures showing this. Feel free to contact me for any additional information. less

Hi, I have this thing working. My diploma was with the same subject. One transmitter with 4 buttons and one receiver with 4 relays and LCD. When a button is pressed it reverts the relay. The display shows the status of each relay ON or OFF. This is almost 90% what you need I only have to change some rows of the program and it will work your way. The transmitter which I am going to use for your project should work at more than 2km. If you have more questions dont worry ask me. I can send you a copy from my diploma so you can see that this have been done. I only have one question about the sizes of the transmitter and receiver: are they in inches?  less
