“It’s like having a thermal camera, just in a lower resolution. To make it even easier to get your low-resolution infrared image, all communication is enacted exclusively via I²C, utilizing our handy Qwiic system”

Technical Description

The on-board AMG8833 Grid-EYE possesses an accuracy rate of ±2.5°C (±4.5°F) with a temperature range of 0°C to 80°C (32°F to 176°F). Additionally, this IR “camera” board can detect human body heat at about 7 meters or less (that’s about 23 feet) and has a frame rate of 10 frames a second to one frame a second. It is important to point out that while this version of the Grid-EYE is the high-performance type with a high gain, it is only 3.3V tolerant. IE: Don’t try to operate it at 5V (you won’t have a very good time).

Applications

Can detect human body heat at about 7 meters

Limitations

It has very specific features which are the following :

1. Operating Voltage(Startup): 1.6V – 3.6V
2. Operating Voltage(Timekeeping): 1.5V – 3.6V
3. Current Consumption: 4.5 mA
4. 8×8 Thermopile Array
5. Temperature Range: 0°C to 80°C (32°F to 176°F)
6. Accuracy Rate: ±2.5°C (±4.5°F)
7. Human Detection Distance: 7m or less (22.966ft)
