Hi,
as successor to the MT13S Aliexpress/Banggood brought the HX1, boasting a 240x240 thermal image.
Requests did not manifest a 240x240 sensor resolution...
The images look very "postprocessed", not as noisy as the ones from the MT13S but also less detailed.
As with MT13S no thermal video possible.
Maybe someone can identify the sensor module?
rgds,
schufti
p.s.: unfortunately up to now there is no sw available to "analyse" the images (*.bmp) like for MT13S

A quick look for true IR resolution on the HX1 did not reveal any useful hits. It does resemble the HikMicro ECO / E01 though and that unit also has a “240 x 240” pixel resolution specification. Hikmicro are honest though and state that the true physical IR pixel resolution is 96 x 96 pixels interpolated to 240 x 240 pixels for presentation on the display. They use a Super Resolution technique to enhance the produced image. Having seen the HK1 for sale at under £100 on Banggood, I would suggest that the camera is too cheap to be a real 240 x 240 physical IR pixel unit.

The HikMicro ECO camera page…….

The manufacturers label on the core is the same format as that used on HikMicro cameras and the PCB even has “HM” stencilled on it. I attach one of your pictures showing the core label, and one from the teardown of my Hikvision (HikMicro) DS-2TP31 camera.

I suspect the core, if not the whole camera, is from HikMicro.

with the whole sensor in HikMikro being built on a solid metal block, it sure is way more thermaly stable than the HX1.
Usually the HikMikro models do the clacking during the calibration phase where they put a thermal referenced mass infront of the sensor, this is missing in the HX1 (it does do "calibration", though).
To round it up: it feels/looks like utter crap, even more than the MT13S.

Ah dam I should have check the forum before buying the E01.
Saw it on sale on Amazon (£50 off, £150 total) (https://amzn.to/4eD9B9l)and went for it thinking it was a good deal for 240x240 pixels.
The B01 is also on sale right now. (https://amzn.to/3UZck5U) 256x192 pixel.
I am quite impressed with the device overall though. Looks like it has a USB camera mode as well which works quite well!
Having tested it around the building, going to keep it. I think it will be fine with PCBs. I don't really do that much debug work but it comes in useful when checking out buildings for thermal issues.
I have found the HX1 Thermal Imaging Camera (https://s.click.aliexpress.com/e/_DBISacl) on AliExpress. It looks the same but claims 240x240 IR resolution.
