Right, I know there are DHT11 and LM35, and kind know LM35 is more accurate, but as I asked above, they are not same, DHT11 is a board, while LM35 is just a part, not sure what are the right words for them, I mean it seems LM35 is very basic and need more welding work, not something just plug or wired like DHT11.
