similar collected, I suggest on esp12 for example, oled 0.96 (but can also be on 2004)
but on oled you can also have pictures, graphics, and animation
if on esp then you can have a web interface and control via MQTT
from 18v20 better on NTC sensors, then hot disconnection and connection of sensors is possible, +18b20 if unlucky you can also get self-heating, NTC are cheap and available
