Hiroyoki:
Any recommend on what temperature should i use?
I would recommend Fahrenheit.
of course you could use Celsius.
....really whatever you like.

Any recommendation of sensors?
the BME280 is a single sensor that offers both humidity and temperature.
it also offers absolute pressure.
the DHT11 is a simple to use sensor, not very accurate and does not have high resolution.
the DS18B20 is a simple to use tremperature only sensors
I would suggest you google :
arduino temperature
arduino humidity
arduino air quality
as for the software, I do beleive that you can copy that code and use it with the exact type sensor.
the free software is the Arduino software you can download from this site.
Hiroyoki:
Sorry typo. Any recommendation on LCD display?
this depends on the microcontroller you want to use :
-Arduino Nano/Uno (328)
-Arduino Mega
-ESP8288
-ESP32
the Nano/Uno can use any of the 2 line LCD displays easily
it can use the Nokia 5110 for more line and different fonts
it can use the 128x64 monochrome OLED as well.
the ESP chips can use those but they can use the larger color displays as well.
the ESP chip have more speed and more memory, so they can send the massive amount of data to the display. if you attempt to use a UNO/NANO with a multicolor display, you may not be happy with the speed.
Hi guy, I need help on selection on board. As uno wifi will be delay until dec. I can’t wait as my project due next month. So which boards should get to have the same function as Uno wifi.
please tell us your abilities.
generally speaking, we would all recomend an UNO for some simple reasons :
-easy to use, most tutorials use this and you do not have to figure out how to transfrom from one device to a different one.
-shields. the UNO offers the use of plug in sheilds. this eleminates a lot of hardware decision making.
as for WiFi,
I would bet that the majority would recomend you get a ESP8266
- very low cost
- minor difficulty in altering the sketch to work with the odd pins
I would be +1 on Paul and his recommendation of the WEMOS D1 MINI
very low cost.
you will need to have some sort of breadboard to allow you to connect more things to the pins.
Basically it is a simple project. I am using sensor DHT22 connect up to uno. As for the wifi, it will transmit/receive sensor data to the terminal. So for the wifi module, which module suit the function?
