I have made an electric sheet on the wireless sensor will be connected. This is just the first version. I can be changed, since i don’t have the parts yet i just did a sheet in my computer.

As you can see on the sheet a 5v battery pack will support the power. I hope it will be good. There will also be an power switch and a reset switch on the sensor, this is good since the Aurdino will be built in.

I also have added two more leds, one for to show that the sensor is powered on, and one for to show when the sensor got an connection with the main system.

Im thinking of add a charger for the battery, but for now this will be the goal.
