AMG88XX Infrared Array Sensor
#############################
Overview
********
This sample application periodically reads the 8x8 temperature array from
the AMG88XX sensor and displays its values to the serial console.
The sample can also be configured to be triggered when the upper threshold
of 27 |deg| Celsius has been reached.
Requirements
************
The Panasonic AMG88XX is an 8x8 (64) pixel infrared array sensor available
only in a SMD design. Here are two sources for easily working with this sensor:
- `AMG88xx Evaluation Kit`_
- `Adafruit AMG8833 8x8 Thermal Camera Sensor`_
On the Evaluation Kit, all jumpers except the J11 and J14 must be removed.
This sample requires a board which provides a configuration for Arduino
connectors and defines node aliases for the I2C and GPIO interfaces.
For more info about node structure and interrupt pin wiring see
:zephyr_file:`samples/sensor/amg88xx/app.overlay`
Building and Running
********************
This sample reads from the sensor and outputs sensor data to the console every
second. If you want to test the sensor's trigger mode, specify the trigger
configuration in the prj.conf file and connect the interrupt output from the
sensor to your board. You can change the upper threshold values by editing
the sample. The default upper threshold value is 27 |deg| Celsius
(80.6 |deg| Fahrenheit).
