Im new to this forum, but i need some expert opinions.
I have a sensor, it gives me only very basic yes/no information - its basically a switch that either connects a circuit (yes) or not (no).
I want to send the smallest amount of information e.g. only when the sensor gives a 'yes', wirelessly.
I want to be able to do this over a fair distance, and I want the transmitter (i.e. the part attached to the sensor) to be as small and as cheap as possible, as there is a good chance it may be destroyed.
so far my guess is RF will be the best option, but I'm no expert, hence I am asking this forum on their thoughts.
any help would be appreciated!
