Hi,

Some news. The electronic system is finished and operational since May 2016. Basically all that was done with multiple thermostats is today by the Arduino microcontroller.

To control my fans I use the PWM mode that is to say the speed is variable depending on the temperature through a cutting signal.

In air conditioning mode, this summer everything worked normally. In October I had a big breakdown, a blocked fan motor resulting in the destruction of a Power Mosfet. As I doubled all stages of power apart from a transistor to change and a few wires a little brown, everything is back in order.


The control is carried out by an independent system based on two arduino nano, consisting of two modules one detector, the other transmitter. I opted for 2,4 Ghz powerful enough with broadcast every quarter of an hour. The system is quite sophisticated, if the temperature is too high yes too low, a buzzer starts to ring, allowing me to intervene quickly.

I have two LCD displays, one in the greenhouse giving alarm setpoint temperatures, fan speeds depending on voltages.

Inside another display give me the temperatures in the greenhouse, in the buffer tanks, the maximum and mini.

So I took my foot ...

I am adding a speedometer directly on the fans, so as to stop the power supply in case of blockage.

Finally, I doubled my installation with copper pipes running around my central table (13 meters in all) powered like radiators, they provide a better distribution of heat with less effort on the fans


I confirm the comments above, arduino is crazy we can do anything or almost ...

Hello,
This is a good example of what can be done with an Arduino. The complexity of editing and the use of PWM outputs have caused you a lot of torment if you are not a programmer. You used a lot of useful functions for any ecologist:
-The ability to vary engine speeds by simply controlling a PWM pin
-Input management (analog / digital) to get your temperatures (ie the arduino can turn its pins in or out just by the program)
-the use of a (shield / additive module) to talk in hertzian (2,4 Ghz I did not know that there were already shields of this level for me only the 433 MHz was common .... certainly the environment of drones that pushed the community to add the shield and it also means that we can transmit video on the fly!) .....

Can you talk about the difficulties or not the coding and the electronic part?
Do you know that the community has developed an interface for us non-C language, in fact I discovered recently that we could program the arduino without a program just with elementary bricks (a breeze).
This is the arduino blocky
http://blogpeda.ac-poitiers.fr/lp2i-si/ ... nvenients/
With this we take a step towards simplicity and I do not think we arrive so easily at the limit of block language because we can still drive robots with this type of simplified language to the extreme ....

More than to know a little about electricity / electronics and only our imagination becomes the limit ....

Hello,

I took the wrong thread. Sorry, the correct thread was "greenhouse heating by thermal pad"

Otherwise we do not understand anything

Hi,

By my job, I used several languages ​​but never in specialist. That said, learning a computer language is like learning a foreign language, for the first it is often painful because you have to think differently, then it's easier.

So the C and C ++ is done quickly at least in a somewhat rustic mode of use ...

Using blocks, several other languages ​​have tried themselves like LaTex. Having used both, there is no picture, hard programming is much more enjoyable than prefabricated products. Finally it is a point of view. It is better to suffer a little at the beginning to then get your foot ...

In fact I suffered very little to build my project, I must say that I took my time and I absorbed a bunch of tutorials on arduino. Trouble we still have, a deposit for which we have forgotten the hysteresis and that it stops it, it starts again, it stops again ...
It may be to set the time on my quartz clock that I have the most trouble!

To control my two 2 fans and pumps (in all 4 DC motors) I used a double motor power stage (2 MOSFET FQP30N06 mounted in parallel) fixed on oversized radiators. So in all 2x4 MOSFET.

For the rest, I used a baby computer case to install the electronics. The advice I can give is that you always have to plan big at the level of the home box, it's quickly full. The motor power supply is supplied by a good quality PC power supply.

I did not use a circuit board, I hesitated, did some tests and opted for a shield with a lot of duplicate connectors on which I installed my arduino uno. The interest is that if the microcontroller is dead, I disconnect and replace a new one.

Regarding the radio link, I opted for RF24l01 with aerial antenna (not printed on the circuit) there is more power. Online libraries include drivers such as nrf24 or mirf. We spend a little time there but it ends up walking ...

I chose a solution like nag: rather than dialogue between transmitter and receiver (the transmitter sends its frame, the receiver waits, if it goes wrong, he informed the transmitter that will restart the frame, etc.) On the contrary, I opted for a powerful emission, always assuring me the transmission, but not to bathe in a new electromagnetic field (there are already enough) I send the data frame at once, all quarter of an hour (hence the need to use a DS313 type clock module.

cordially





I used as the case welds + heat-shrinkable sheaths, sugars and wagos ..

Thank you for mentioning your approach it can give ideas.
For my part I program a little but I will try to use the simple method of blocky arduino (google is behind this concept anyway), the risk being of course to reach the limit of blocky (which I doubt) and then to have to program afterwards. The flexibility of this block language however allows any handyman to launch without fear. What I like is that it is experienced at the level of teaching and passionate level. One can easily go from the visual block to the coded transformation and one can do so mix (code / block) some professional have pushed the language by simply using flowcharts. I also think that the flowchart mode is more suited to our management system '' econologue '' but I preferred the block that also allows to better understand the program at first glance (initiated or uninitiated).

For my part, I will test the implementation of an intelligent heating management system only with "block" even if I have already done programming (which I reserve for the specific beyond the capacities of the blocks) . I will use the "shield" as much as possible (clock, relay, Ethernet ...). I want to avoid the complexity of the program, increase the ease of troubleshooting (program and add-on module) and have the set duplicated (arduino uno and the "shields" for instant troubleshooting). It seems more than reasonable to me for a heating management system.
Block management seems to me less subject to errors, in fact when a hysteresis valve management block on 2 setpoint T ° is achieved, a simple block displacement makes it possible not to repeat the problem (the copy paste of a language being more difficult because there is often slightly different coding along the program)
Of course, I will also do results "reporting" to optimize solar thermal management in the long term, which goes without saying with the arduino.

In agreement with you, the shields simplify the life and in case of failure, a standard exchange immediately solves the problem. Your IT approach may also be easier to debug than x pages of lines of code.

I have just recently discovered an "arduino shield" developed only for "reporting" and management operations for all of the home energies.
it's the monon EMonTx Open Energy shield. It is able to measure the actual electrical energy consumed, injected or returned to EDF using its hall effect sensors, 4 input provided for this purpose (current measuring clamp without disconnecting the installation).
It also has specific inputs for temperature and voltage measurements. An 433 Mhz link and an RJ45 output to transfer data to a dedicated site. The user only has to install his measurement points and use his PC or smartphone to see different graphs.
If the user has to manage the numerous outputs it is of the arduino program ...
