سلام اساتید محترم هدف ساختن یه ترموستات برای کنترل دما و رطوبت هست از nodemcu استفاده کردم ال سی دی و سنسور dht11 و رله دو کانال الان از طریق کلید ها و ال سی دی هم دما و رطوبت رو میتونم ببینم و هم کنترل کنم تو قسمت وب سرور هم کد html اضافه کردم که طبق عکس میتونم دما و رطوبت و حداقل و حد اکثرشو ببینم ولی نمیدونم چطور میتونم اون تکست باکس هایی که برای ورود حداقل و حد اکثر هست طوری تعریف کنم که حالت ورودی داشته باشه و اعداد رو به نود بفرسته و اونجا برابر با متغییر های حداقل و حد اکثر رطوبت و دما قرار بده لطفا یه نگاههی به کد بندازید و در صورت امکان برام تغییرش بدید که بتونم از صفحه وب متغییر ها رو کنترل کنم.
