Hello Today I'm looking at the infraray P2 Pro thermal Imaging sensor. So this is the camera or sensor. Um, it's a USB type C for Android phones. it's very tiny.

I'll just put an A cell there so you can see the size of it. It is really quite small and also in the box is this macro lens. so I'll just take off the lens cover and that simply sticks on with a magnet so it's pretty quick to put on. So this is a 256 by 192 high resolution thermal imaging sensor.

It's also 25 frames per second, although it doesn't do that absolutely continuously because periodically it self-calibrate so you do see little jumps in the continuous movement. The macro lens does get you very close I'm guessing about two inches or something like that, but occasionally that's useful if you want to look at some small electronic components. Okay, let's get um, some Electronics which is going to give off some heat and take a look at the images. Um, through the app which I'll run on my Samsung phone and you can also record video which is going to be really handy for this video.

Okay, here's the app: Uh P2 Pro You can get that from the Google Play Store and I can either run that app or I think I can just plug in the thermal imaging camera into the USBC port and it will detect it and run the app for me right? Here's the app running on my phone and I'm looking at this Buck Boost Power supply and we can already see that there is or there are some hot spots this one over on the left even without the macro lens. I Think you can see that that is an eight pin chip. but let's put the macro lens on and get in a little bit closer. so the macro lens just snaps on like that and now I can get in really close and you can see all the detail.

The legs of the chip are fairly reflective so they're showing up well basically what is being reflected in them, but the body of the chip you can see there is quite warm and the temperature there is, uh, 40 degrees in the center of that IC Now that's a small buck regulator. I see and it's the main power supply for all the electronics, including the microcontroller on this unit. Lying down on the board looks like a possibly a two pin. that's possibly uh oh.

the tab may be being used as the third connection. I Can't remember what that device is. Let's have a look on the board. Okay, I've switched to my video camera on my phone and No.

I think the device we were looking at was actually that heatsink there. So let's go back into the thermal imaging camera software and switch to video mode. Um, no. actually there's the heatsink with the standing up to 220 device on it.

There's actually a device lying down in there and it is what I thought it was. It's a T0252 or something like that. I'll just switch back to the normal camera so that we can see that yes, the device we were looking at is actually down in this gap between that heatsink and the and it is a T0252 I think or something like that. Uh, down in that Gap Yes, I Couldn't see that at first because it sort of tucked under this Um display board.

Well, now that was with this buck boost converter switched off. So let's switch it on and see how the temperature profile on various components has changed. Actually, let's just check the current which is 200 milliamps. Well actually not much.

It seems it's the same suspects which are warm. I'll just snap on the macro lens and we'll take a closer look again. again. that eight pinch here for about 40 degrees.

Another eight pin chip there 38 degrees. the T0252 oh, that's quite warm. that's 43 degrees. and I think there was something over here.

Oh, that could be a resistor. Let's have a look. Uh, yes, it is a resistor. It's uh, three three.

Oh oh so it's a 3k3 and I've got a feeling that's across the capacitors, so it's just, uh, discharging those output capacitors. Well, now here's another Um heating. Appliance This is actually an infrared heating panel. It's 180 watts and it's really quite intriguing.

So I'll just switch into the thermal imaging camera and uh, you can see that there really isn't anything to see perhaps apart from apart from my own reflection. But let me switch that on and things will look very different, right? I've just turned on the power. Oh, you can see my foot there, but um, can you see that pattern emerging Now The resolution of this sensor is such that you can actually see I Don't know whether you'll be able to see my hand here. Yeah, um.

the wiring inside this panel? Yes, I can feel the heat coming off it, but you can see the connection point and a cable inside the panel and you can see all these sort of heating cells which are just completely unaware of. Um, if you look at using a normal camera. So yeah, back to my normal video camera. And of course, there's absolutely nothing to see apart from again, a few Reflections possibly.

So let's go back to the thermal imaging camera and I will turn that heating panel off and something quite interesting happens. So there again is the pattern of the heating cells. and it's interesting because there are parts of this which are so hot you can't touch them. Um, but there are other parts up in these Corners Um, which are not as warm and oh, you can touch them and in fact, you can use your finger to suck the heat out of that panel, right? Let me switch that off.

which I can do here. Um, off and watch what happens as um, the thing is not directly being heated by. this is Mains powered. It's 220 volt electricity.

You can see there that as the Heat starts to dissipate, as it starts to spread, the image appears to go out of focus. It's not out of focus, it's perfectly in Focus But the heat is spreading from what were the hot heating centers to the cooler areas. And yeah, you just lose the definition of that heating pattern. I'll switch it back on again.

So that's it. Switched back on and fairly quickly you see the detail of those heating cells comes back in well. I say into Focus It's really not much to do with Focus it's to do with the concentration of heat in the heating elements and so that's what's inside. You can't see that with the naked eye, but that's in what's inside one of those infrared heating panels.

What's the highest temperature? about 75 degrees and I now have come outside into the garden. and yes, the patio looks, uh, pretty. Uh, Kaleidoscopic doesn't it? And I'm out here with these two solar panels. and I Noticed something yesterday on the thermal imaging camera which was a little bit concerning.

I'll just switch into the Infrared app. Uh, yes, of course. I Remember now I disconnected. Um, the two connections around the back of the panel because it was causing a really strange effect.

I'll reconnect them now. Yes, you can see I've disconnected. There's one of the Mc4s and the other ones over there. so I'll connect those back together again.

So I've reconnected the two Mc4 connectors on the back of that panel. It does seem to set the dog off. so let's switch back into the thermal imaging software and what I noticed was that there were some cells which seemed to be quite a bit hotter than adjacent cells. So for example, there's one cell here, which is much warmer.

In fact, there's one down there, which is quite a bit warmer. Let's actually feel that. And yeah, you can actually feel that that cell is warmer than adjacent cells. So what's going on here? I've got a funny feeling that the terminal voltage, of course, has to be zero because I've shorted out the Mc4s, but are some cells generating voltage and other cells perhaps going inverse voltage? But um, yeah, it's only really with the thermal imaging camera like this that you can see that strange effect.

And here's a really interesting effect on the thermal imaging camera. Well, you can see my reflection, but you can also see the cell bottom right is much warmer, but only in its top left hand corner. Let's go back to the normal camera and you'll see why. and the reason is that that cell is half shaded.

so the bottom right of that cell is probably cold. And it is. But the top left is warm. and in fact, it's a lot warmer than adjacent cells.

I'll go back into the thermal imaging camera. Yes, that's really interesting, isn't it? So by partly shading that cell, it's doing far less work than all the other cells. and as a result I think it's been driven by the other cells, so it's getting hotter. Yeah, that's really interesting and it shows the effect of partial shading on a solar panel.

So that shows a few of the things you can do with this: Infrared high Resolution: 2 5, 6 by 192 pixels thermal imaging camera with 24 or 25 frames per second video, you can shoot actual thermal imaging videos of interesting things that get warm.
