Task 2 -  indoor climate

Analysis of the indoor climate

Learning goals

The sensor station will be used to analyse the indoor climate, and will issue a warning if the specified limit values are exceeded or not met. The measurement series can be collected using the IoT server and then analysed.
 
Understanding the term relative humidity
Understanding how to measure noise level (decibels)
Understanding the term illumination level (lux) and determining this value based on the values from a photoresistor
Learning typical limit values for relative humidity, temperature, volume, and illumination level
Deriving an index value from multiple measured values based on a specified weighting

Topic

Measuring factors that impact indoor climate (relative humidity, temperature, air quality, brightness, volume)
Defining and measuring a “ventilation indicator” for classrooms (“CO2 traffic light”)
Determining illumination level

Time required

If the sensor station was constructed previously in task 1, then no time is required for construction. 
120 minutes is the suggested time to solve the programming tasks (building on the weather station from task 1).
Solving experimental tasks 1 and 2 requires the student to create a mathematical mode; students may require support to do so. The suggested time required to develop the program (depending on programming experience) is 120 - 80 minutes.
