"Uncle, there is another entrance on the first floor, right?"
Oh! Are you a Conan detective?
That's it! Do you want to say that an invader might be able to enter from there?
The man must go through another door to get there ...
But I've always been concerned.
So, I installed another sensor in the next room.
"Where does the sensor notify?"
It's wirelessly connected to the main unit on the first floor.
"When my aunt enters the next room, if the alarm sounds, she'll be paralyzed with it!"
That'll be too bad! But most of the time, she turns on the lamp before she enters.
People who invade enter in the dark, but ...
It's a secret, but when the lamp is on, it doesn't give an alarm.
"Are you trying to make the sensor inconspicuous, this time also?"
Yeah, even Conan will have a hard time finding it!
Also, I added parts so that it can record when the alarm is given. You see, this is the part.
"How do you record on such a small object?"
I wrote that in this book as well.
Hoping it helps you when you grow up.
"Thank you! It seems difficult, but I'll read it."

This is a description of the part added to the device in step-1.
On the 1st floor, we added a wireless device XBee so that we can get information on the next room. Also, on the 2nd floor, EEPROM(S93C46A) was added to store various values. We hope that it will be helpful for those who are planning to build a similar system or those who are thinking of a more advanced system.

This time, using the XBee XB24-B we obtained the respective values from the motion sensor and illuminance sensor in the Box installed in the next room. The connection between the main unit and the added router side XBee, and between the end device and sensor.
