Laptop Thermal imaging project

Projects General Guidance

Hi, so the goal of my project is to use the adafruit 8x8 thermal imaging camera and have it send live data over the wifi to my laptop, where my laptop will then turn that into a visual heatmap.

I would also need to know how to control the sensor's shutter, also maybe how open or close the shutter is, can't really find this info anywhere.

I plan on using an Arduino UNO and the ESP8826, I know nothing else about what to do or how to do it. I'd appreciate any help, thanks

You mean an ESP8266?

Send the readings over serial to a Processing application running on the PC/laptop, and use the Processing to display the results as rectangles of colour.

5

Why the Uno bottleneck. The ESP8266 is a capable processor on it's own.
Leo..

6

The sensor has no shutter to control. You just read out 64 values when they are ready, about ten times per second maximum.

7

The attached picture shows and array that will update at a rate of 10Hz, how would I assign it to a variable. This variable array will be passed to processing language to map the data.

How many entries will there be in the array and what type of variable do you expect to be able to hold the values ?

Please post the code that creates the data shown ? Can you not simply send each value to Processing instead of writing it to the Serial monitor ? In fact, it is already being sent to the Serial interface

So I want to hook up this thermal camera Adafruit AMG8833 IR Thermal Camera Breakout [STEMMA QT] : ID 3538 : $44.95 : Adafruit Industries, Unique & fun DIY electronics and kits

To the adafruit feather huzzah ESP8266 Pinouts | Adafruit Feather HUZZAH ESP8266 | Adafruit Learning System

Are they able to connect?

And followup, will it even be able to send the data correctly to Processing without needing an actual micro-controller such as an arduino UNO? The camera sends an 8x8 array at a maximum frequency of 10 Hz if it matters. Thanks.

The camera output via the I2C bus so you can't send directly to Processing. You could read the camera with the 8266 and send the data via serial to the Processing program. I have used I2C with 8266 and it is no different than using I2C with any other Arduino (except you can choose the pins).

This page has wiring, library link and example code.

Ok so it is feasible, thank you.

And, (sorry im new to this process), What do you mean by sending the data via serial to the processing program? Does this mean wired or could I still do it wirelessly from the adafruit feather ESP8266?

This article has some wireless 8266 options for sending data wirelessly.

Lots of threads merged.

Exactly, maximum. This implies there would be some sort of command to decrease it. No ideas?

Here is the code that made that 8x8 array of numbers

#include <Wire.h>
#include <Adafruit_AMG88xx.h>

Adafruit_AMG88xx amg;

float pixels[AMG88xx_PIXEL_ARRAY_SIZE];

void setup() {
Serial.begin(9600);
Serial.println(F("AMG88xx pixels"));

bool status;

// default settings
status = amg.begin();
if (!status) {
Serial.println("Could not find a valid AMG88xx sensor, check wiring!");
while (1);
}

Serial.println("-- Pixels Test --");

Serial.println();

delay(100); // let sensor boot up
}

void loop() {
//read all the pixels
amg.readPixels(pixels);

Serial.print("[");
for(int i=1; i<=AMG88xx_PIXEL_ARRAY_SIZE; i++){
Serial.print(pixels[i-1]);
Serial.print(", ");
if( i%8 == 0 ) Serial.println();
}
Serial.println("]");
Serial.println();

//delay a second
delay(1000);
}

Im new to this stuff but I understand Serial.print(####) will make the microcontroller wirelessly send data to the Serial monitor and then display it. I'm not sure how to send it to processing, and then define it as an array, instead of Arduino.

No, it does not imply any such command. The sensor converts values every 1/10 of a second. You can read them out if you wish, or not. You can set it to convert at 1 frame/second, but there is no real difference in the performance.

You clearly don't understand how this sensor works. Each pixel measures the temperature of whatever it is pointed at, which would include the temperature of any "shutter" you cared to put in front of it.
