Remote room temperature measurement via the Internet over twisted pair, 500 PLN?

I am looking for a solution to remotely measure temperatures in several rooms, preferably from a browser and from an android phone.

Ideally, I would like to be able to connect the sensors using the twisted pair cable I already have stretched in the walls.

What is the cheapest possible option on the market? What solution can you suggest?


I know you can use a PCL but it costs over 500PLN or is there something cheaper?
or what PCL model do you recommend that is not too complicated to use?

kind regards

Try a 1-wire to RS-232 converter, to this any computer - can be an old one for 50PLN, as DS18B20 sensors. On the computer a web server, results generated on the website. The only thing is that it is not a ready-made working solution, you have to make your own website with the measurement results. A bit of an amateur solution, but it was supposed to be cheap.

Well it could be more expensive e.g. 300-400PLN which means only PCL is left:)

A thermometer like this, for example:

and visualisation software on your PC?

LAN Controller should meet your expectations in terms of temp measurement and price.... only someone on the electrode mentioned that it can hang up.... also for the low price, but you probably need to use it a bit to gain confidence. There seems to be a version that allows you to connect 4pcs. DS18B20.

Welcome,

Gentlemen I don't want to start a new topic, but I have a similar dilemma. For me, cellular input is not important. I would like multiple sensors m.i.n wells (water and air temperature) in the ground (at different depths) and of course in the house. I browsed through a well-known auction portal, but did not find any ready-made solution that would meet my needs. However, I found a solution based on DS18B20 sensors in a brass housing + 1-wire / RS 232 interface + free LAMPOMITTARI application. The vendor claims that the sensors can be connected in parallel and in series while maintaining polarity, and can be extended using a UTP cable. What I do not understand is how the programme detects 12 sensors (this is how many the vendor has installed). What do you think about such a solution?

Hello,
If the measuring locations are not more than 200m away then you can use a wireless temperature logger.
AR434 will take care of your air and water temperature (built-in sensor and possibility to connect for example Pt100
and AR406 is a collective station of these sensors with a regulator function, because it has 4 relay outputs, so it will be able to switch on something even some kind of alarm if it is important.

and a sample temperature sensor for the AR434

The AR406 is 1000 PLN net plus ETHERNET 400 PLN net and transmitters, so it's quite a sum.
The question is whether it should make money or not, as far as I know it is successfully used by companies, I don't think anyone has bought it just for home.

Hi,

Thanks for the quick reply, I'm looking to install this at my house, I'm having a major renovation right now, I'm moving with all the installations in the spring. I would like to have everything on cable (I will have too many wireless devices). It would be lovely if I could have a view of all temperatures at once (could be a windows app). I'm looking for a slightly cheaper solution (I was thinking so up to £1500 for just the control panel and 16 sensors)

I'll only be able to get you a Pt100 in a sealed design for about £85 each, just depends on how much cable.

I recommend getting interested in Lan Controller from tinycontrol.pl The small board has its own web server and the possibility of connecting various analogue, status and digital 1wire sensors. The project is being developed all the time. A very cool feature is the action table (Even config), which allows you to program on/off relays/email, SNMP traps depending on the set detector states. You can also collect readings or receive set events by email. I am attaching a screenshot of one of my house controllers, it shows the temperatures from the living room, from above the fireplace mantle, and the 4 primary temperatures of the heat pump (lower and upper I/O). The attached relay is from the PC's large fan blowing on the fireplace
The second Lan controller acts as a twilight switch (photoresistor as thermistor odp corrected) and watering controller. And this is thanks to the fact that a scheduler is available for on/off time programming. It is also possible to set up remote control so that a sensor from one Lan Controller triggers a relay in another on the same network, and many other functions, such as a watchdog to monitor IP devices on the Internet. Another version of the firmware, yet to be developed, is designed for smart homes, e.g. allowing the control of lighting from a button on the wall and remotely or automatically via the controller.
