IOT Room Sensor

Basics

• An IOT "Cube" / "Brick" that can measure the following information and relay it to the system:
  • At Least:
    • Temperature
    • Humidity
  • Additional Data, But Will Add Some Cost:
    • Carbon Dioxide Concentration
    • Light Level Sensing
    • Nitrogen Dioxide Concentration
    • Ozone Concentration
    • Particulate Matter
    • PIR Based Occupancy Sensing
    • TVOC Concentration
• Some form of basic display would be nice, preferably low power such as a basic LCD screen, labels and Seven Segment Displays / Nine Segment Displays , or an E-Ink Screen
• Leave Smoke Detectors / Carbon Monoxide Detectors as a seperate unit / units?
