micro:Environmental Science Environmental Science Board

SKU: MBT0013

Based on micro: bit, this environment expansion board is closely concerned with natural science. We hope through the natural subjects' combination, the maker education can be close-to-life. Therefore, we integrated multiple sensors in this expansion board like atmospheric pressure, temperature, humidity, UV rays, light, color, sound, water quality, water temperature, soil moisture and so on. Which covers all basic aspects of natural science and daily life. In the process of learning, students can learn the measurement principles of various natural data. And by programming their own graphical program to measure the relevant data, it deepens the understanding of knowledge, as well as the recognition of natural science.
