Google recently rolled out the ability to measure body temperature in the Thermometer app in the Pixel 8 Pro smartphone, as a part of the January Pixel feature drop. The app is the first FDA-granted body temperature app for smartphones. Here’s an explainer on how it works and how to use it.
Google Pixel 8 Pro temperature sensor
Google Pixel 8 Pro comes with a contactless temperature sensor on the camera visor. When the phone was launched, it allowed users to measure the temperature of different surfaces and objects such as metal, organic, and liquid, among others.
It measures the infrared radiation emitted from the item and shows a temperature reading ranging from up to 392°F (200°C) to -4°F (-20°C). The January Pixel feature drop expanded the capability of the sensor. It can now quickly scan a person’s forehead and measure the body temperature.
How to sensor and Thermometer app
Bodies emit infrared radiation, or heat. The Pixel 8 Pro’s infrared sensor to measure the body temperature. To measure a body’s temperature on the Pixel 8 Pro, point the rear camera at the forehead and sweep across.
“The Pixel 8 Pro body temperature app accurately measures your temperature by scanning the temporal artery, unlike less accurate forehead thermometers that are pointed at the centre of the forehead,” Google said.
The data from the infrared sensor is passed to an algorithm to calculate the temperature that is displayed on the phone’s screen. Google highlights the role of Tensor G3 chipset in implementing this feature.
Google also said that Pixel 8 Pro’s infrared sensor has a wide field-of-view of more than 130 degrees that helps it to sense heat beyond the forehead when the phone is too far away from the forehead.
“In clinical trials, our software algorithm was able to calculate body temperature in the range of 96.9°F – 104°F (36.1°C – 40°C) to within ±0.3°C when compared with an FDA-cleared temporal artery thermometer. In layman’s terms, this means the Pixel body temperature feature is about as accurate as other temporal artery thermometers,” Google claimed.
