Temperature sensor and car accident detection

The Apple Watch Series 8 temperature sensor is the biggest upgrade on this year’s watch. There are actually two sensors, one below the screen and one at the back, closer to the skin. This should improve accuracy by helping the watch distinguish the temperature of your wrist from other factors that affect the temperature in your environment. The watch measures your wrist’s temperature overnight every five seconds and tracks it in the Apple Health app.

Since this is a negative reading that happens overnight, I wasn’t able to try it out in the Apple demo room. But I found out how to present this information in the Health app. The app will display changes in baseline temperature in an in-app chart, along with context about the meaning of the data. The company says shifts in your core temperature can be an indicator of exercise, jet lag or illness. There is also a new wrist temperature box in the Health app summary section where you can tap on this data.

Apple positions the temperature sensor as the most useful for tracking a woman’s health. Temperature sensors allow the Series 8 to provide retrospective ovulation estimates and improved menstrual cycle predictions.

The Apple Watch is also getting a new security feature this year: car accident detection. If the watch detects a malfunction, it will notify the emergency services and emergency contacts of the wearer if the wearer is unresponsive for 10 seconds. This is only available on the new Series 8 and SE models and the Apple Watch Ultra because it uses an updated gyroscope and accelerometer.

Another noteworthy addition is the Apple Watch’s Low Power Mode, which Apple says should extend battery life by up to 36 hours for the Series 8. The new Low Power Mode turns off features like the always-on display and automatic exercise detection to preserve functionality while extending life. the battery. Although Apple just announced the feature on Wednesday, it will also be available for Series 4 and later. Otherwise, the Apple Watch battery life is generally the same at 18 hours.

The overall design of the Apple Watch appears unchanged this year. The Series 8’s size and overall shape remain the same, and it will be available in Midnight, Starlight, Silver and Red produced with an aluminum case. The stainless steel version, which I tried during my time with it, will come in silver, graphite, and gold.
