4-channel temperature measurement with LCD display and recording of measurements

Hello !

I am looking for at least a 4-channel thermometer (4 temperature measuring points, range -20...+125°C) which displays the temperatures measured on "real time" and has the possibility to save a sequence of measurements to files for analysis with e.g. Excel. I need this for temperature measurements on a coil boiler.
I found such a kit: 8 channel thermometer with alarm and LCD display (avt pl shop model avt5489) and such a kit: Temperature recorder with USB interface (avt pl shop, model avt5230)
I would like something that is a combination of these two kits, i.e. 4÷8 channels of measurement, LCD display, logging to PC via USB or SD card, could be a DIY kit.
If any User has encountered such a device I would be grateful for help and advice on where I can buy such a device.

Regards,
Tomek

Hello, have you found anything? I would also need such a display and data storage solution.
A question for the more knowledgeable would using these two modules from the atv and common sensors connected in parallel work correctly? Or perhaps via relays?

Welcome.

Unfortunately I didn't find anything like this, but I'm still looking for

If anyone has a lead on a similar device to the one described in the topic then please let me know.

Regards,
Tomasz

I think this is the wrong place for this thread. It seems an easy matter to succeed with two putters using the same temp sensors.

Hello
There are ready-made solutions e.g:
http://www.dopomiaru.pl/produkt/wielokana%C5%82owy-rejestrator-danych-ar205
or
http://www.wentylacja.biz/produkt,21097,kompu...atury-model-krt-807-dc,pomiar+temperatures,,1
Alternatively, commission someone to make such a logger, but this will not be cheap anyway.

Nice equipment you sent indeed it is not cheap, but it is a starting point. Something more amateur would be useful

Do you necessarily need a range up to +125°C ?

Not for me, I don't know about the author. For me, up to 30ºC would be enough.

I need this device to record the temperature on the central heating cooker, including the pipe that discharges the flue gases into the chimney. Probably 125 degrees C on that pipe is not, but I don't know how much it can be.
I have two cookers - one solid fuel and there I guess the range up to 125 seems reasonable though, the other is a gas cooker but definitely not low temperature. In the latter case maybe a limit of 80 degrees would be OK.
Obviously a net price of 1400 is not what I'm looking for. I want to compare out of curiosity how the modulation of the burner flame depends on the water temperature in the central heating system, and how often the burner switches on depending on the water temperature in the system. It is this modulation that I want to assess indirectly by measuring the temperature on the flue pipe to the chimney.

I can see that the subject has come up a bit

Edit:
I'll also add that it could be some sort of self-assembly device, price in the range of £100-200, without a super enclosure, as much as possible with cables hanging out, more or less as I stated in the first post. Unfortunately direct links were not able to be attached.

I have to worry you, but you won't buy one anywhere for that price.
At least I was not aware of such recorders at such a price.

I was thinking of something to solder up myself. E.g. if you type something like this into Google (avt shop pl model avt5489) the price is £110, when you type in (avt shop pl, model avt5230) we have a price of £48, so a total of about £160. More or less something that will be a combination of the two is what I'm after. I care about saving data via USB because I don't want to sit in the morning for several hours and write down data from the temperature display

Welcome.

It is enough to read a little about ARDUINO , and the measurement of temperature, for example by sensors DS18B20 and its recording .Programs almost ready (sketch) , you can find through google , and colleagues from the subsection
arduino" sub-section colleagues in the subsection "Arduino" will probably help in adding, or direct a colleague to write the rest of the code.

Regards.

You have boilers not cookers, and a range of 125 degrees is far too low for a solid fuel boiler (although I don't know exactly what boiler you have)
I wonder what you need these measurements for and what you intend to do with them?

With the kind of requirements you need I doubt you'll find one for £200.
And with self-assembly kits and shops I know their offer you do not need to explain to me. The fact that a set costs e.g. 10zł and the other e.g. 15zł does not mean that both combined (functions) will cost 25zł. Such recorders are expensive and the more features they have the higher the price goes up x2 or x3 if not more.

Thank you for your answers.

I want to get an idea of how often and for how long the gas boiler switches on and at what output (gas consumption) depending on the temperature outside and indoors. I am unable to determine this by sitting in the boiler room (which is probably why I have boilers and not furnaces ) because it would take too long. If I had a graph of the temperature on the boiler feed and on the outlet pipe to the chimney then I could get an idea of how the boiler works. On the boiler you set the temperature at which you want the water in the system to be heated and the boiler operation, i.e. the frequency of switching on and the length of a single cycle depends on this temperature. If I had the chart I wrote about above it would make it easier for me to set the right temperature on the boiler. Let's skip the fixed-fuel boiler for now.

ARDUINO is an interesting idea, I'll have to look into it, but probably after Christmas as it's a headache right now

You're probably right that the price won't be the sum of the sets, but I was hoping I might be able to find one reasonably priced after all. As I wrote above I'm going to read about this ARDUINO, as it seems like it would be the quickest and easiest way to get the temperature sensor I wrote about in the first post built.

Thank you all for your replies, and I wish you a peaceful and joyful Christmas

Hello.
Here you have an example , just on the sensors LM35 , you can still to Arduino eg: uno add a time module , and you will still have the date and time of measurement . You can also add an SD module and save to the card , or via a wi-fi module , if you have coverage there , your network .

Hello,
maybe such a controller would come up. You can connect to it two PT100 sensors in the range -50..+160 degrees. And via RS232 connect to a computer and in some terminal record data from sensors.

I can offer my friend a PLC with hmi and program for a reasonable price
