A Python3 library for interfacing the Melopero AMG8833 breakout board with a Raspberry Pi.

Melopero AMG8833

Getting Started

Prerequisites

You will need:

• a python3 version, which you can get here: download python3
• the AMG8833 grid eye sensor: buy here

Installing

You can install the melopero-amg8833 module by typing this line in the terminal:

sudo pip3 install melopero-amg8833

Module description

The module contains a class to easily access the AMG8833's sensor functions.

Usage

First you need to import the module in your file:

import melopero_amg8833 as mp

Then you can create a simple amg8833 object and access it's methods, the sensor object will be initialized with the i2c address set to 0x69 and the i2c bus to 1 alias (dev/i2c-1) which is the standard i2c bus in a Raspberry pi.

sensor = mp.AMGGridEye()

Alternatively you can modify it's parameters by typing

sensor = mp.AMGGridEye(i2c_addr = myaddress, i2c_bus = mybus)

The sensor has the following methods

sensor.set_fps_mode(fps_mode) #sets the fps mode there are only two options: AMGGridEye.FPS_10_MODE or AMGGridEye.FPS_1_MODE
sensor.get_fps() #returns the current fps 10 or 1
sensor.update_pixel_temperature_matrix() #updates the pixels matrix
sensor.get_pixel_temperature_matrix() #returns the last updated pixel matrix
sensor.get_pixel_temperature(x, y) #returns the spicified pixel's temperature
sensor.get_thermistor_temperature() #returns the temperature of the thermistor

Example

The following example will print out the temperature and the pixel temperature matrix every 0.1 seconds (10 fps)

import time
import melopero_amg8833 as mp

sensor = mp.AMGGridEye()
sensor.set_fps_mode(mp.AMGGridEye.FPS_10_MODE)

while(True):
    #print temperature
    print(sensor.get_thermistor_temperature())

    #update and print matrix
    sensor.update_pixel_temperature_matrix()
    print(sensor.get_pixel_temperature_matrix())

    #wait 0.1 seconds
    time.sleep(0.1)

Attention:

The module is written in python3 and by now supports only python3, remember to use always pip3 when you install the module and python3 when you run the code.
