The AMG88xx (AMG8833 / AMG8831) from Panasonic is a Grid-EYE matrix infrared sensor capable of simultaneously boardping 64 temperatures (8×8 pixels). It detects heat (infrared radiation) from the human body or any other object. The sensor is equipped with an I2C interface making it possible to recover the thermal image. The measurement frequency can be up to 10 measurements per second.

Please note, this sensor does not offer sufficient accuracy (± 2.5°C) for medical use. It should not be used for medical purposes such as detecting COVID-19. For example, it can be used to detect presence, fault diagnosis by thermal analysis, etc.[/ wpsm_box]

There are two generations of the AMG sensor. The current (33,34,53,54) and old (31, 32, 51, 52) versions. This is the reason why we often find the two references on the daughter boards (breakout). The most common part number is AMG8833 / 31.
