Yes. That's the exact problem. You're asking a question that would require a book to answer. Especially when you factor in the whole web server aspect. That's a whole other complex topic.
What you probably need is some sort of off the shelf product, designed to do what you want -- some sort of environmental monitoring system. I don't know of one, personally, but perhaps someone else has an idea.
In may day -- back decades ago -- the problem of distant sensors might be solved with 4-20mA lines. These days, something like SPI, or I2C, might be used if the lines aren't more than 20 feet long, or some other digital-serial solution like RS485, or even Ethernet, which can work with longer runs. I suppose you could also use something like WiFi, but that seems like overkill to me--ala: The more complex a system, the more things to go wrong.
For a website, perhaps a Raspberry Pi running something like "LAMP" or "XAMPP". I'm versed in PHP, so that's what I would use to build the site, along with Javascript, jQuery, JSON and AJAX, for a seemless realtime display update. Maybe a Python app would monitor the I2C connections, and send that data via CURL and HTTP to send POST requests to the PHP webserver script.
And, what-the-heck -- thinking in terms of a wireless solution, perhaps each sensor could be paired with an ESP module for a WiFi connected solution. That way, firmware in the module could send HTTP POST requests directly to the PHP script.
But, that's just me thinking out loud.
