Google has finally retired one of the Pixel Pro line’s more unusual hardware features. The Pixel 11 Pro replaces the infrared temperature sensor introduced with the Pixel 8 Pro in 2023 with a new HiLight RGB LED built into the camera bar.
That brings the thermometer’s run to three generations. The sensor appeared on the Pixel 8 Pro, stayed on the Pixel 9 Pro and 9 Pro XL, and returned again on the Pixel 10 Pro and 10 Pro XL before disappearing from the Pixel 11 Pro. Google’s own support documentation confirms that those five models are the phones that support its Thermometer feature.
From experimental sensor to discontinued hardware
Google introduced the temperature sensor as a distinctive Pixel 8 Pro feature. The infrared hardware could measure the surface temperature of objects without physical contact, while a later software update expanded the system to body-temperature readings.
That second use case gave the sensor a more practical purpose. Google received FDA De Novo classification for its body-temperature feature in January 2024, making it the first smartphone body-temperature app to receive that classification in the U.S.
Still, the feature never became a defining part of the Pixel experience. Google continued to carry the dedicated hardware through the Pixel 10 Pro generation even as the company shifted much of its product focus toward cameras, Gemini, and computational photography.
The Pixel 11 Pro changes that equation.
HiLight takes the sensor’s place
The new camera-bar layout leaves room for HiLight, an RGB LED that provides visual alerts on the rear of the phone. HiLight can be used for notifications involving contacts and Gemini, while leaked Pixel 11 hardware had already shown a single opening where previous Pro models carried the temperature sensor.
The replacement is significant because Google is not simply deleting unused hardware. It is reallocating that physical space to a feature designed around notifications and the company’s increasingly AI-focused software experience.
That makes the decision easier to understand. A thermometer required dedicated infrared hardware and a separate app, while HiLight can provide a persistent physical signal without requiring the user to look at the display.
A feature some owners will miss
The thermometer was never universally useless. Pixel owners have reported using it to check body temperature, food, drinks, and other objects, although experiences with its accuracy and frequency of use vary.
Google’s own implementation also had limitations. Object measurements require the phone to be held close to the target, and body-temperature measurement depended on specific software and regulatory approvals.
For most Pixel buyers, removing the sensor is unlikely to change everyday phone use. For the people who actually relied on it, however, the Pixel 11 Pro marks the end of a feature that survived longer than many expected.
The more interesting question is what Google does with the space next. If HiLight proves useful enough to earn its place on future Pixel models, the thermometer may end up remembered less as a failed experiment and more as hardware that eventually made room for a different idea.
