Unofficial tests have found that the new Pixel 8 Pro’s temperature sensor is pretty accurate most of the time. The sensor has to be calibrated for the type of material you’re scanning (for example, shiny metal or fabric), so you have to enter that manually. Then you just hold it within 5 centimeters of the object and let it do its thing.
One user posted on Reddit that they were able to use the sensor to determine what items in their fridge were still safe to eat when a storm knocked out their electricity for 36 hours. “Using it, I could easily identify food items that were nearing their melting point, allowing me to make informed decisions about what to discard and what to keep,” they noted.
