The Panasonic AMG8833 is an 8\u00d78 infrared thermopile array. It returns 64 individual temperature readings over I2C and includes a configurable interrupt output. The source describes use with Arduino or Raspberry Pi and image interpolation for display.<\/p>\n
The sensor measures a coarse thermal grid; it is not a conventional visible-light camera or a certified fire\/security detector.<\/p>\n
The following source code initializes the sensor, reads 64 pixels and prints them to the serial monitor.<\/p>\n
