Please help me about my thesis. Answered
Hello. I'm currently taking an Electronics course. I have a thesis. So here's my thesis idea.The purpose of my thesis is for children's safety. A child will have to wear a watch wherein it will send off signals continuously and when the receiver which is inside an extension receives the signals emitted from the child's watch it will trigger the outlet to switch off then the appliances plugged in that extension will be off. As for the extension I'm gonna put a relay circuit inside an extension wherein any appliances could be plugged in. My problem is what transmitter and receiver am I gonna use to trigger the circuit to switch off? Should I use Bluetooth? But it doesn't auto-connect as far as I know. Can I use Zigbee shield? Does it have transmitter and receiver? What microcontroller should I use? Please help me. :( Thanks in advance!
