Wireless sensors for monitoring people and their close environment

The purpose of many of these sensors is to capture the human condition with something, data, which is entirely inhuman. Knowing the temperature, a person's heart rate and whether they have opened a window is not the same as knowing if they are happy with the internal environment. So why does an equivalence need to be established between measurable data and feelings or preferences?

The most common sensor system in buildings is the thermostat, yet many buildings do not even have one. A building with no sensors and no intelligence just has people and manual controls. If the person is too hot he or she opens the window, turns on the air-conditioning or takes off a jumper; or perhaps all three. The human being is a thermostat, a sensor and an intelligent control system in one, so why try to improve on it?
