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`_
|
||
|
|
|
||
|
|
We used the Evalutation Kit mounted on FRDM-K64F board.
|
||
|
|
On the Evalutation Kit, all jumpers except the J11 must be removed.
|
||
|
|
|
||
|
|
This sample uses the sensor APIs and the provided driver for the AMG88xx sensor.
|
||
|
|
|
||
|
|
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. For the FRDM-K64F we tested, pin PTC2 must be muxed as
|
||
|
|
GPIO. You can change the upper threshold values by editing the sample.
|
||
|
|
The default upper threshold value is 27 |deg| Celsius (80.6 |deg| Fahrenheit).
