FLIR Lepton 3.5 (500-0771-01) is a thermal camera module array with 80x60 and 160x120 active pixels available. It is used with the 250-0577-00 development board for SPI interface to an embedded computer like the Raspberry PI. Engineers can also consider the 2077-PURETHERMAL-M-ND development board which uses a USB interface and plugs into the USB port.
The part does not have a fixed tolerance. This is a thermal imaging sensor with performance that is impacted by many environmental factors further described in its datasheet. If you are not designing an embedded solution with this part and simply requires a thermometer, you can consider the finished product. For example,
