Hello,
may be silly, but it is of general interrest for me.
I think on a unit, as big as a wrist watch to locate my cat or my child (or my wife :lol: ) - only max 30 meter distance.
Receiver unit has a display and show me in an analog bar the distance to the transmitter unit.
Transmitter unit send every second to the receiver unit.
If the contact is lost - I get an alarm on the units.
questions:
can be done this in such a small system like a watch?
can this be done on 400Mhz?
are there electronic parts (receiver/transmitter units) or system on a chip .... to do this.
Please give me some links (in the right direction), so I can study and read about it such kind of electronic parts.
do you think ist is possible to handle with one receiver unit a lot of transmitter units? (If I have a lot of children or girl friends and cats)
- and my neighbor has also such a equipment.
are there other technical risk?
if someone have interest to send a comment will be nice
