Hi, I am a new member to this forum and it has been 15 years since i last worked with a PCB at uni!!
I am in the process of designing / inventing a piece of kit and require help and advice combining various bits of electronic knowledge.
Simply, what would i need to transmit simple information such as temp, a switch position (on / off) to a base unit (which would be mains fed or rechargeable battery) over a distance over less than 1 mile (2 at most). There would also need to be a sound transmission as well.
There would need to be about four parameters, and hopefully distinguish different sets of sensors (no more than 4).
I have had a play with simple "walkie talkies" and it would seem this would be the cheapest / smplest route to go down with a few modifications. Also had a play with a simple RC car.
Any initial help to point me in the right direction would be appreciated.
PKH :shock:
