BONUS SECTION. Nora Sensor Basics

The Nora has 6 different sensors on board. These are:

1. Temperature - measured in Celsius (Texas Instruments Datasheet)
2. Temperature & Humidity - measured in Celsius and percentage (Silicon Labs Datasheet)
3. Ambient Light & Proximity - ambient light includes IR and UV measurements, as well. Ambient light is measured in Lux, IR is used for Ambient Light corrections if IR levels are high, and the UV values must be divided by 100 to give UV index. Proximity (from what I could tell) is measured in cm. (Silicon Labs Datasheet)
4. Accelerometer - measured in g (STMicroelectronics Datasheet)
5. Air Pressure - measured in hectaPascal (STMicroelectronics Datasheet)
6. Magnetometer - measured in gauss (STMicroelectronics Datasheet)

Temperature, humidity, pressure, and ambient light measurements are always useful for monitoring environmental conditions. Acceleration and orientation can be nice for something that's moving - like a robot or car. And the fact that the Nora is battery operated makes it even more useful for scenarios where it needs to be moving.
