This Project plans to offer basic environmental data and most importantly information about the current UV intensity at camp. It us based on an inexpensive (3-ish EUR) esp8266 Module and a string of sensors attached to an i2c bus. The Module ran a NodeMCU Firmware with a set of lua scripts at first. The Firmware has now been reimplemented in C because of problems with (power) efficiency. FUN FACT: reimplementing did not help it was an issue with the hardware setup.
The Sensor has been working since Day 1 but due to the "difficult" wlan environment isn't always reporting measurements.

UV Index Chart
| UV Index | Media graphic color | Risk of harm from unprotected sun exposure, for the average adult | Recommended protection |
|---|---|---|---|
| 0–2.9 | Green | "Low" | Wear sunglasses on bright days; use sunscreen if there is snow on the ground, which reflects UV radiation, or if you have particularly fair skin. |
| 3–5.9 | Yellow | "Moderate" | Take precautions, such as covering up, if you will be outside. Stay in shade near midday when the sun is strongest. |
| 6–7.9 | Orange | "High" | Cover the body with sun protective clothing, use SPF 30+ sunscreen, wear a hat, reduce time in the sun within three hours of solar noon, and wear sunglasses. (Australian slogan: Slip-Slop-Slap-Seek-Slide.) |
| 8–10.9 | Red | "Very high" | Wear SPF 30+ sunscreen, a shirt, sunglasses, and a wide-brimmed hat. Do not stay in the sun for too long. |
| 11+ | Violet | "Extreme" | Take all precautions: Wear SPF 30+ sunscreen, a long-sleeved shirt and trousers, sunglasses, and a very broad hat. Avoid the sun within three hours of solar noon. |
