Google details how the Pixel 8 Pro’s thermometer works

Google Pixel 8 Pro Review AM AH 05

In the latest January Feature Drop for the Google Pixel 8 Pro, Google introduces a noteworthy upgrade to the smartphone’s thermometer, enabling it to measure body temperature. The Google Pixel 8 Pro’s infrared sensor was initially designed for object temperature measurement. However, now it offers a contactless way to gauge body temperature. Google Health’s team, working diligently to integrate health tools into Pixel phones, developed this feature, aiming for convenience, accuracy, and hygiene.

Google Pixel 8 Pro’s thermometer sensor works with a remarkable precision of ±0.3°C

The Pixel 8 Pro’s body thermometer sensor is positioned near the rear camera, allowing users to scan their temporal artery by sweeping the phone across the forehead. Google considers this method more accurate than traditional forehead thermometers, providing a temperature range of 96.9°F – 104°F (36.1°C – 40°C) with a remarkable precision of ±0.3°C. The company’s clinical trials confirm the accuracy of this feature when compared to an FDA-cleared temporal artery thermometer.

To enhance the user experience, the Pixel 8 Pro incorporates the LDAF (laser detection autofocus) sensor. It detects the phone’s proximity to the forehead before initiating a measurement. This ensures optimal positioning for accurate readings. Additionally, haptic feedback and audio instructions guide users through the process, making it user-friendly.

The Pixel 8 Pro’s infrared sensor boasts a wide field of view (over 130 degrees) and requires the phone to be within half an inch of the skin for accurate readings. The team emphasizes the contactless nature of the measurement. It prevents the spread of germs, addressing concerns related to hygiene.

FDA has finally approved this thermometer function

Google underwent a rigorous FDA De Novo classification process for the thermometer feature, ensuring it meets the standards of regulated medical devices. This involved a clinical validation study with a large number of participants, focusing on accuracy, safety, and ease of use. The approval underscores the thermometer’s reliability and its ability to function without an internet connection. It makes body temperature measurement accessible even when you don’t have access to any thermometer but your phone.
