Introduction¶

Adafruit CircuitPython module for the AMG88xx GRID-Eye IR 8x8 thermal camera.

Dependencies¶

This driver depends on:

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Usage Example¶

Of course, you must import the library to use it:

import busio
import adafruit_amg88xx

The way to create an I2C object depends on the board you are using. For boards with labeled SCL and SDA pins, you can:

import board

You can also use pins defined by the onboard microcontroller through the microcontroller.pin module.

Now, to initialize the I2C bus:

i2c_bus = busio.I2C(board.SCL, board.SDA)

Once you have created the I2C interface object, you can use it to instantiate the AMG88xx object

amg = adafruit_amg88xx.AMG88XX(i2c_bus)

You can also optionally use the alternate i2c address (make sure to solder the jumper on the back of the board if you want to do this)

amg = adafruit_amg88xx.AMG88XX(i2c_bus, addr=0x68)

Pixels can be then be read by doing:

print(amg.pixels)

Building locally¶

To build this library locally you’ll need to install the circuitpython-travis-build-tools package.

Once installed, make sure you are in the virtual environment:

Then run the build:

Pixel test¶

Ensure your device works with this test:

examples/amg88xx_simpletest.py¶

import time
import busio
import board
import adafruit_amg88xx

i2c = busio.I2C(board.SCL, board.SDA)
amg = adafruit_amg88xx.AMG88XX(i2c)

while True:
    for row in amg.pixels:
        # Pad to 1 decimal place
        print(['{0:.1f}'.format(temp) for temp in row])
        print("")
    print("\n")
    time.sleep(1)

class adafruit_amg88xx.AMG88XX(i2c, addr=105)[source]¶

Driver for the AMG88xx GRID-Eye IR 8x8 thermal camera.

pixels¶

Temperature of each pixel across the sensor in Celsius.

Temperatures are stored in a two dimensional list where the first index is the row and the second is the column. The first row is on the side closest to the writing on the sensor.
