This resolution is expressed in pixels. Yet while these are very handy heat sensors they are not available in this resolution in an Arduino compatible version. To my surprise an 8X8 pixel thermal scanner for Arduinos is on the market since approximately , that is, a sensor mounted on a breakout board with i2c communication and ready to be used with an Arduino figure 1. This development makes experimenting with thermal scanning within reach of every Arduino hobbyist.
Temperature range is oC with an accuracy of 2. I2C address is 0x The breakout device is 3. Sensor device: probe holder Typically a thermal imager needs to point towards the object to be scanned. From the designer point of view there are several options. The design of the probe holder is illustrated in figure 3.
Wiring The diagram in figure 2 shows all the wires that connect the microcontroller board, the display breakout and the AMG breakout. Wiring for the thermal scanner breakout is the following. AD0 is an optional pin meant to set the I2C address. Default AD0 not connected is 0x Once the AMG is initialized it sends a stream of temperature readings from its 64 pixels. This stream is translated into gray values and these are projected onto the display.
This the resolution of the Arduino thermal scanner figures 4,5! Because there are 64 squares on display I constructed a gray lookup table LUT that contains 64 shades of gray. It must be noticed here that bit color convention in Arduino needs gray levels and all other colors to be represented according to the RGB scheme. Results A classical way to test infrared cameras is to aim the camera at a cup with hot coffee. Testing went perfect figure 5. Prices are reasonable which makes the MLX very attractive for further experimentation.
The processing and display of thermal information in 1, pixels may go beyond the limited capacity of the Arduino Uno. You are commenting using your WordPress.

A real-time infrared camera IR camera was introduced as a way of monitoring temperature for applications in person counting, heat transfer of electronics, indoor comfort monitoring, industrial non-contact temperature measurement, and other applications where multi-point temperature monitoring may be useful.
The approximate error of the sensor over its operable range is 2. This tutorial is meant as the first in a series of heat transfer analyses in electronics thermal management using the AMG The Arduino, in this particular case, will communicate with a Windows computer via the serial port and send data from an Arduino-compatible sensor, which will subsequently be read by MATLAB through its serial communication library.
I will also introduce a real-time analysis and plotting routine to visualize the Arduino data as it arrives in real time.
