Single Device to Control Many Arduinos with NRF24L01+ Sensor

STORY

About This Project
Trying sensor network with NRF24L01+ as what maniacbug did. Though I could only afford to build network with 5 modules.

This build will only have one MCU, the Raspberry Pi, to connect to Cayenne. The great thing with NRF24 is that it reduces clutter in your dashboard while controlling a lot of stuff.

What's Connected
Raspberry Pi (this is connected to Cayenne) Arduino Nano (MCU for the devices we are controlling) NRF24L01 (RF module) Zero Crossing circuit SSR DHT11 PIR sensor Light switches (these are override switches, just in case you want to manually switch device) Wall Power supply (I cant find those with switches, so I added mine into it).

Triggers & Alerts
Proximity sensor will tell if you have visitors at your door. At night, this could turn on a light whenever it detects motion.

When it gets too hot, it turns on your fan (due to SSR limit, but change SSR then you can turn AC) when the temperature drops below lower limit, turn off fan.
