leXsolar-ESave Ready-to-go

Thanks to the leXsolar-ESave Ready-to-go, discussions about energy becomes more tangible. The approach is holistic: the students focus first on issues like global energy consumption, climate change or energy consumption at private households. Based on the question-at-hand, students will make measurements based on the problem; for instance things like room temperature or climate, water and energy consumption, etc. The goal is to foster the ability to identify potentials for improvements and savings.

Key data:

• With the help of this combination of instruments, the following topics can be analyzed and optimized:
  
  • Electrical energy consumption
  • Heating behavior
  • Air quality
  • Water consumption of a school/household
  • Lighting
• Optimal for energy saving projects in the classroom
• Many measurements can utilize an automatic Data Logging System
• Includes a detailed introduction to the topics for students, excercise sheets for the respective measurements and an experiment quide for teachers

Components:

• 1× Data Logging USB base station with power supply
• 3× Temperature sensors for inside use (temperature range: -30 °C – 80 °C/-22 °F – 176 °F, measuring accuracy: ±0,5 °C/0,5 °F)
• 1× Combined humidity-temperature-sensor  (0 – 100 % relative humidity, accuracy ±4,5 %, temperature range: -40 °C – 120 °C/-40 °F – 248 °F, ±0,5 °C/0,5 °F)
• 1× Temperature sensor for outside use (temperature range: -30 °C – 80 °C/-22 °F – 176 °F, measuring accuracy: ±0,5 °C/0,5 °F)
• 1× Digital Light Meter (0,01 – 50000 Lux)
• 1× Infrared thermometer
• 2× Electricity meter
• 1× Flow meter
• Detailed worksheets
• Robust aluminium case with foam inserts
