AMG8833 8x8 Thermal Imager Array Sensor

Unlike a single-point IR thermometer that only reads one temperature value at a time, the AMG8833 reads an entire 8x8 grid of infrared temperature readings simultaneously - genuinely a (very low-resolution) thermal camera rather than a single-spot sensor, capable of distinguishing a warm object's shape and position within its field of view rather than just confirming something warm is present. That's a meaningfully different capability from a basic PIR motion sensor, which detects motion but tells you nothing about shape, position or actual temperature.

With a detection distance up to 7 meters for human-scale heat sources and a 60-degree field of view, it covers a reasonable room-sized area from one mounting position. Frame rates of 10Hz or 1Hz (selectable) trade refresh speed against power draw, and sleep/standby modes bring consumption down to fractions of a milliamp when not actively sampling - relevant for any battery-powered deployment.

Common uses are people-counting and occupancy sensing that needs to distinguish a person's shape and position (not just presence), non-contact appliance and building automation systems, and DIY thermal-imaging projects wanting genuine spatial temperature data rather than a single averaged reading.
