Thermopile Array Development Support

To get started with instrument development based on our thermopile infrared imaging arrays, we offer quick access to your first thermal image to help you achieve rapid development progress. For quick plug-and-play access, we provide a USB Application Set with our windows based software to get started with the thermopile array sensor. Explore its possibilities and see if it is suited for the application you have in mind. This will enable you to take a quick decision on suitability before you start a software and support hardware development process.We also offer a software development kit (SDK), which is basically an Arduino shield capable of operating all of our different thermopile array sensors. With the documentation and software, you will be guided through the process of getting the thermal image read out of your sensor.

USB Application Set

Our USB application sets consist of HTPA thermopile sensor packaged with lens mounted on a small PCB with signal processing and power set in a modular metal housing for thermal image capturing and easy evaluation of our thermopile array data. It is a plug-and-play solution and all you need is a Windows PC with our FREE ArraySoft software installed. Just plug-in the USB connector and see your thermal image. The user can instantly start evaluating the sensor for suitability to the intended application, measurement and test.

The USB application sets are available with all Heimann HTPA arrays from 8x8 and 16x16 to 32x32 and 80x64 pixels with various lens options. The target temperature range of the USB application set is determined by the sensor type.

 

  • HTPA thermopile array sensor with 8x8 to 120x84 pixels
  • USB communication and power supply
  • Graphical User Interface (GUI) for visualization with:
  • Temperature display
  • Interpolation & data log mode
  • Control up to 10 independent devices

 

Application Set (UDP communication)

We designed an application set in a modular metal housing for thermal imaging and an easy evaluation of our array data.
The modules'  field of view depends on the built-in lens and can be varied on demand. The object temperature range depends on the array type and lens.

For every array type, we additionally provide a matching application set in our portfolio, which allows full sensor control. The application set processes the data and communicates via Ethernet/UDP to a PC. On PC side, the data stream can be visualized and logged with a Graphical User Interface.

With the given software the user can instantly start with sensor evaluation, measurements and testing.

 

  • HTPA thermopile array sensor with 8x8 to 120x84 pixels
  • UDP communication (Ethernet)
  • Graphical User Interface (GUI) for visualization with:
  • Temperature display
  • Interpolation & data log mode
  • Control up to 10 independent devices

 

WiFi Thermal Imaging SDK

For this next step of development, our aim was to create a set without cables to make the SDK a versatile tool for development and sensor evaluation. This became possible through the emerge of the ESP32-DEVKITC-32E boards with WiFi connectivity, which is available seperately: Digikey Partno. 1965-ESP32-DEVKITC-32E-ND.

 

Hand in hand with our new Application Shield and corresponding source code, it is possible to connect array sensors wireless to our ArraySoft v2 GUI and show realtime thermal images. From 8x8, 16x16, 32x32, 60x40, 80x64, 84x60 and 120x84 to all future generations, this will be possible with just one add-on board.


The open source software is available on our Github Site: https://github.com/HeimannSensor

  • ESP32 shield for thermopile array software development
  • Full C++ sample code to read thermal image data
  • Completely open source
  • Graphical User Interface (GUI) for visualiziation with:
  • Temporary display
  • Interpolation & data log mode
  • Control up to 10 independent devices

Measurement Spot Calculator

The measurement spot calculator can be used to determine the area that can be observed with a given sensor.

First select the resolution and subsequently select the lens with the field of view (FOV) that you are interested in. By entering the measurement distance you will instantaneously get the resulting measurement area in the given distance from the sensor.

Besides width, height and diagonal of the area the results will also give you the instantaneous field of view (IFOV) of a single pixel. Please note, that the IFOV is only an approximation and can vary for each pixel due to grid distortion of the lens system. This is especially true for very wide field of view sensors, where the edge and corner pixels have a larger distortion and therefore field of view than the inner pixels.


Also note, that the minimum distance to get a sharp image varies with the selected lens and focal length of the system. As a rule of thumb, 20 times the focal length can be assumed as the distance for a sharp image.
