I need to build a simple universal adapter that use PIR Sensor to turn on/off the current. For now, I use Arduino Mega 2560 but I want to utilize cheaper board if possible (please give suggestion). The board should use external power source provided by wall socket (no USB, so you should consider correct current so it won't damage the board) and should convert back the current on output.
I have a web server to handle data transmission on adapter's status. So, the adapter must send some data through wifi module. I use TLN13UA06.
Each adapater has its own ID and all of them will be waiting for the right signal, once received it should open relay and send status to my web server.
Here's what I need:
1. Hardware schematic
2. Arduino Sketch to set Wifi, PIR Sensor, and to give adapter ID
3. All needed programming
4. Easy-to-understand documentation
