Graphs display the data from the last two days, so we can compare how weather was changing and their impact on our well-being. And as you know, changes in the weather are vital to our health.
Low air pressure lowers blood pressure, and during the lowering of the atmospheric pressure in an atmosphere of oxygen content decreases. As a result, human blood pressure drop and the flow rate, there are problems of interference with the breathing and the cardiovascular system, often also accompanied by headaches.
At high temperature and high humidity of air, with a low atmospheric pressure, problems may be elderly people, especially suffering from arteriosclerosis or renal failure, since in these conditions also greatly decreases the concentration of oxygen in the atmosphere.
In contrast, excessive drying of air (especially common during long-term use of air conditioning) may be the cause of dry rhinitis, which at this condition becomes more susceptible to viral infections.

Variable weather has a big impact on our health. In application, however Sensors can control its impact on your well-being.

Temperature measurement also indicates the current location, and humidity sensor currently prevailing conditions in a given location. It also allows an individual to determine the scale for measuring humidity.
In addition to the actual pressure barometer indicates changes in the weather, and altimeter allows the measurement of the change in height (for example, when you walk up the stairs or simply move the phone hand up and down). This allows us to measure the height at which we enter or descend.

For proper operation of required sensors are temperature, humidity and pressure built into the phone.
Internet connection is only required to display your current location. Without the connection location is not shown, but the measurements are functioning properly.
