Hi everyone! I developed keen interest in electronics and my inability to find information is really bothering me. I have this little project that I wanted to build. Its a diary which I can only open if my wireless key is in proximity. I would like to know whats the technical name for this sensor and wireless key.
Maybe a good way of starting is to ask what kind of signal is used for this? I thought initially its Bluetooth but I've seen this design with little thin key chains so maybe that could be too big for it. Anyways if if someone could give me some insight into how this sensor works I would be grateful. Please keep in mind I'm a novice at this and so far I have made a LED lamp and a simple Servo lock.
