Description

Microclimate measuring device

The invention relates to a microclimate measuring device, and in particular to a microclimate measuring device capable of simulating multi-level wearing of a human body.

When the human body wears clothes, it feels comfortable or not because of the change in temperature and humidity between the skin surface and the clothes or between the clothes and the clothes.
