Electronics analyst Sun Chang Xu reports on her Weibo account that the next iPhone may add a pressure, temperature and humidity sensor. G for Games relayed the report and points out that the “pressure” in this context is certainly atmospheric, not blood pressure: “According to Sun Chang Xu (news chief analyst at ESM-China), sources close to the matter have revealed that Apple will catch up in the “sensors department”, as the iPhone 6 will feature pressure, temperature and humidity sensors. Please note that the analyst is probably not referring to blood pressure (this feature is rumored to be implemented in Apple’s iWatch) but to atmospheric pressure.” This same analyst previously reported that Apple may use “optical sensors” to measure heart rate and oxygen levels in the rumored iWatch.
