Modular box for iot project

**Update 26/05/2016**

Add two more boxes :
- **box_air** wich is for temperature sensor, to prevent false temperature from converter.
- **box_t_h** which stands for "Temperature and Humidity"

**Update 05/20/2016**

I just remix the boxes with round angles, top is now throated and i add a new temperature top for DS18B20.

**Description**

I build some esp8266 / multi-sensors iot for my MQTT broker and i was in need of pretty container for them.

This is 42x42x42 box for esp8266 build (or other arduino build).

The boxes can be customized with different tops.

Specificity :
- **box_motion** is for HC-SR501 infrared motion sensor
- **box_display** is for i2c OLED 0.96" display
- **top_luminosity** is for TSL2561 luminosity sensor
- **top_gaz** is for MQ-2 gas sensor
- **top_temperature** is for DS18B20 temperature sensor
