AMG8833 Arduino Processing Code Schematic Non-Interpolation

Panasonic AMG8833 Arduino

AMG8833 Arduino Processing Code and Schematic Non-Interpolation - AMG8833 is an infrared array sensor manufactured by Panasonic. The AMG8833 sensor has 64 pixels with a resolution of 8x8.

AMG8833 Arduino

 

The AMG8833 sensor can be used in various applications that can detect temperature without touch an object.

 

The AMG8833 sensor is very good for use in temperature selection applications, electronics manufacturing, detecting the position of humans or objects and others.

 

This Panasonic AMG8833 Infrared array sensor has a maximum value:

• The maximum VDD voltage is 6.5 VDC
• Input Voltage (SCL, SDA, AD_SELECT) up to 0.3 VDC
• INT and SDA currents up to 10mA.

 

AMG8833 Arduino Circuit

AMG8833 uses I2C to communicate with the microcontroller. The pins used are SCL and SDA. Please assemble the sensor  to Arduino as in the following image.

 

Download AMG8833 Library

To make  easier to work in accessing the data from the amg8833 sensor, we need a library. There is already a library available below, please download it.

Download AMG8833 Library

Then, include the library into your arduino IDE by steps:

• Click the Sketch menu
• Then select Include Library
• Click Add ZIP Library
• Navigate to the downloaded library file
• Click OK

Now, I have coded the program below. There are two program codes, namely, for Arduino IDE and for Processing. 

AMG8833 Arduino Code:

#include <Wire.h>
#include <SparkFun_GridEYE_Arduino_Library.h>

GridEYE grideye;


void setup() {
  Wire.begin();
  grideye.begin();
  Serial.begin(115200);
}

void loop() {
  readAMG();
}

void readAMG() 
{
  for (unsigned char i = 0; i < 64; i++) 
  {
    Serial.print(grideye.getPixelTemperature(i));
    Serial.print(",");
  }
  Serial.println();
}
