Comparison of Three Popular Thermal Cameras for Smartphones; infiray’s value is comparatively higher



Comparison of Three Popular Thermal Cameras for Smartphones; infiray's value is comparatively higher

Today I want to share a useful tool – thermal camera for smartphones. During circuit design or troubleshooting, thermal cameras can directly “see” the temperature distribution. So that it’s easy to find thermal issue during design. There are only a few brands of thermal cameras on the market. I have used Flir one pro and Seek compact pro before. Recently I got one Infiray T3S. Below is my test and comparison.

d.    Lens.

The working wavelength of thermal imaging is 7-14µm. The best lens material is Germanium. Some producers use less expensive synthetic materials. According to my investigation and directly consulting with manufactures. I got the lens materials are as follows:

  • Flir one pro – vulcanized synthetic material
  • Seek Compact pro – vulcanized synthetic material
  • InfiRay T3S – Germanium

Lens size- Flir one, Seek Compact Pro, InfiRay T3S

For infrared application, Germanium has best transmission of 95%. It can reach 99% with AR coating. Versus synthetic material can reach 95% with AR coating. Generally, cameras with better lens get clearer pictures and accurate temperature measurement.

2.   Image Quality

The main functions of thermal cameras are imaging and temperature measurement.

Resolutions of the three models are:

  • Flir one pro       – 160×120,with regular camera 1440×1080 pixels
  • Seek Compact pro – 320×240
  • InfiRay T3S      – 384×288

Let’s compare the images.

a.    Close-up Image

­­After overlapping with visible light, images from Flir one pro improves a lot. The thermal image and regular image are matched pretty well.

Image from Seek compact pro looks similar to Flir one ‘s 160×120. Even it is 320×240.

Image from InfiRay T3S is much better. The 384×288 pixels gives more- detailed and rich, sharp image.

b.    Close-up Portrait

Images from Flir one pro are better than the one from Seek compact pro, even its resolution is lower. The overlapping needs improvement because the visible and thermal images don’t match very well.

I took many pictures with Seek compact pro but could not get good one. The lady’s hair and background almost mixed.

Image from InfiRay T3S is much clear. Even the lady’s face detail and hair can be seen.

Close-up Portrait Scores

Flir one pro5 for thermal only 6.5 for thermal and visible overlap

InfiRay T3S9.5

c.    Medium Range Image

Above pictures were all taken at about twenty meters distance.

The images of Flir one can hardly distinguish subject and the reflection from floor. And the thermal and visible image overlap matching problem is more obvious.

Seek compact pro is better than Flir one pro on details. The person and its reflections can be distinguished.

Image from InfiRay T3S is the best. The person’s head, arms, legs can be seen clearly.

Medium Range Image Scores

Flir one pro3 for thermal only 5.5 for thermal and visible overlap
Seek Compact pro4.5
InfiRay T3S9.5

d.    Long Range Image

The image from Flir one pro without visible overlap is very blur. With visible overlap the different floors can be seen.

Seek Compact pro is better. Windows can be distinguished.

InfiRay T3S can “see” windows more clearly, and other details such as logo on the building, street lights and trees.

Long Range Image Scores

Flir one pro3 for thermal only 5.5 for thermal with visible overlapping
Seek Compact pro5
InfiRay T3S9.5

From all images mentioned above, InfiRay has best image quality. It provides more detail and rich display.

3.   Temperature measurement

  • Flir one pro       range -20–400℃, accuracy ±3℃ or ±5%
  • Seek compact pro       range -40–330℃, accuracy unknown.
  • InfiRay T3S      range -20–120℃, accuracy ±2℃ or ±2%

InfiRay T3S doesn’t have widest range but has best accuracy. ±2℃ or ±2% is the industry standard so it can be directly used on professional industries such as electric power industry. As for circuit design, since people could get burned with PCBA that is above 60℃, -20–120℃ is more than enough.

a.    Body Temperature Measurement

  • Flir one pro – 35.5℃
  • Seek Compact pro – 33℃
  • Infiray T3S – 36.13℃

The measurements from Flir one pro and InfiRay T3s are close. And they match with normal body temperature. The measurement from Seek compact is quite off.

b.    PCBA Temperature Measurement

Flir one pro, with the help of visible overlap, can see positions of components, however the problem is that the thermal and visible images not match well.

Seek compact pro is hard to find positions of components. Just could barely see PCBA itself.

InfiRay T3S got a clear image and easy to locate the components that has highest temperature.

c.    Parameter Settings

Parameter settings affect measurement accuracy. All three models have emissivity setting. Flir one pro and Seek compact pro both provide a few fixed options. It’s easy for regular users, however, advanced users are not able to set emissivity for specific material to get accurate measurement. InfiRay T3S has emissivity, ambient temperature, humidity, distance settings to fine-tune the measurement. This function is very helpful for hardware engineers to get accurate temperature measurement.

Parameter Settings Scores

How to Set up a Cardano Node?



How to Set up a Cardano Node?

The constant evolution of the blockchain has made it a more mainstream technology. Such improvement contributes to its rapid market growth. Blockchain technology came along with Bitcoin in 2008, the first-generation blockchain that can facilitate only cryptocurrency transactions. Later, when Ethereum (second-generation blockchain) entered the blockchain space, it set a new definition of how blockchain technology can power enterprise-grade solutions and eliminate the need for third-party authentications.

Amidst the blockchain advancement and the advent of new protocols, scalability continued to create challenges for the first and second-generation blockchain users. Besides, lack of interoperability is another reason that disrupts the global utilization of diverse blockchain use cases. Blockchain experts realized the potential adverse impact of these short flaws, and thus we had the third generation blockchain, Cardano, in 2017. This article will explore Cardano, its diverse use cases and discover how to set up Cardano node. So, let’s start.

What is Cardano?

Cardano is a third-generation proof-of-stake blockchain platform designed to be open-source and decentralized. It addresses the challenges of first and second-generation blockchains. In addition, it eliminates the flaws of POS (proof-of-work) consensus mechanism such as high transaction cost, slow transaction processing, high energy consumption, etc.

Due to its open-source nature, the platform offers a range of Cardano development opportunities for worldwide developers. One can easily participate in the Cardano ecosystem and contribute to its sustainability by developing innovative solutions like a Stake pool, smart contracts, Cardano exchanges, and even a unique ecosystem.

What is a Cardano node, and how it works?

A node is the core component of the Cardano ecosystem that underpins the whole network. Ultimately, every blockchain network consists of various interconnected nodes to validate transactions and blocks via a consensus mechanism. Specifically, in Cardano, users are required to run Cardano node if they wish to join the platform and contribute to the open-source project.

So, how does a Cardano node work?

A Cardano node is a service node that imparts complete transparency across the network by validating how the pool interacts inside the network. The nodes further hold and manage the combined stake in a single entity.

Other core responsibilities:

Production of blocks

Cardano produces independently verifiable blocks across a peer-to-peer protocol through a robust block-producing system. It further adds security layers to decide which blocks should be added to extend the chain.

Validation of transactions

Nodes validate the transaction by appointing slot leaders who determine if the sender has enough funds to meet transaction parameters. Once confirmed, the slot leaders record data and assume it as an active block after the complete verification process.

How to set up a Cardano node?

We will discuss the step-by-step process of setting up the Cardano node from the source node and running the node into multiple operating systems.

For that, you need the following component setup for node installation:

  • The latest operating system- Windows, Linux, or macOS.
  • Dual-core CPU with 8GB RAM and 10GB disk space.

For Linux

Step1: Install operating system dependencies on the Linux system.

Step:2: Install GHC and Cabal using ghcup.

Step3: Download and compile a working directory to store source code and builds.

Step4: Configure the build option.

Step5: Build up and install the node.

For macOS Operating system

Here, we will explain the download, compilation, and installation process for the node.

Step1: Install operating system (OS) dependencies for MacOS.

Step2: Install homebrew packages.

The rest of the steps are the same as the node installation in Windows operating system (from step 3 to step 5).

For Windows operating system

Node installation for Windows is the same as macOS and Linux, but you need WSL (windows subsystem for Linx) that changes the windows environment into Linux.


With a highly mutative nature and the ability to embrace modern technologies, Cardano has brought significant change to the blockchain and its real-world implementations. Such overwhelming popularity has also empowered Cardano-based development & deployment services since this protocol supports scalable, interoperable, and sustainable enterprise-wide solutions at a reasonable cost.
