Hi. Interesting project, I congratulate you for your initiative. A year ago I made a project very similar to this one (you can check it in my profile) to regulate the temperature of the interior of an attic. All this by opening windows and turning fans on and off. All this project was done using AutomationDirect brand PLC with some parts such as digital input modules, relay output modules and thermocouple modules. The sensors measure the temperatures inside the attic and on the outside and as the case the actuators are turned on to close or open the windows and turn the fans on and off. I would like to know what type of PLC brand you want to use, what kind of sensors you have in mind. In case you have not chosen any I can make some suggestions. If you want to ask any question or comment please do not hesitate to contact me. regards Pardo Darwin

Hello, how are you? I hope you have a bright day/evening from your side. I have read the details provided, but please contact me so that we can discuss more on the project. I believe I have the required skills in this case. I will work on your requirements personally since I do not outsource to third parties, this guarantees you high-quality work that is delivered on time. You can also request for revisions till you’re fully satisfied with the work. I believe research is a passion and not a money making business where people will deliver low-quality work just to get paid. Try my services, and you will never regret. Waiting for your kind response

Hi, Are you open to a Raspberry PI or Arduino implementation? The boards can be programmed to read and take action based on the readings from the sensors. We'll have to review the connections to the sensors, first of course, and then I suppose to attach a relay capable of powering up the fans. Would you like to explore this option further? This is placeholder bid, the final price will be different depending on the details. Regards, Sergio
