I need a circuit to control up to 99 remote triggers.
Must include a circuit for a transmitter (a simple button like car alarm) with a easy jumper codification from 1 to 99 and a receiver capable of identifying each trigger and comunicate with a computer via USB serial port.
The trigger must be able to transmit from a distance of 100 meters with or without walls, but I need the price for 500 meters of transmission range too.
The receiver must continuously send a byte with zeros until it detects a trigger pressed.
When the receiver identifies a trigger, must send a byte with the trigger number. The byte must be sent while the trigger is pressed and must stop when the trigger is released.
The design must consider the cheapest construction too.
Please send me the cost for design the circuit and to make a sealed prototype for 2 triggers only with a simple application to read the port and show the triggers status on screen. I can pay via paypal, moneybookers or western union.
If the prototype works ok, then I can pay for the design and for a full working set for 50 triggers.
Thanks
