Making some General purpose wireless sensors/controlers

[TommyGunn]

Hey everyone,
Out of boredom I’m making some wireless devices for use as door sensors, light sensors and some other sensors to and outputs to just control things around my house. I’m working on the hardware alone so perhaps you guys can scrutinize my work.

Here is the schematic. Hoping to run a batch of these boards in a week or 2. Thoughts? Maybe I can add some stuff to make it better?
