How to create a weather station at home?

Question

Arduino

Good afternoon!
As a hobby, I decided to set myself a small task.
Description of the task: Build a system for measuring temperature and humidity in a room with the output of information from the sensor to the ios device.
I divide this task into two subtasks: devices and software.
There are no problems in the software part. iOS + Node.js Server.
Designing a device here, my knowledge for today is 0, so I ask you to recommend me from the open source world:
1. A good and high-quality chip, temperature, humidity.
2. Good and high quality wifi and blue chip.
3. A reliable microcontroller of the minimum size that will transfer data from the device to ios and node.js via wifi or blue.
4. How to connect it all into one device.
PS Please do not scold the amateur for questions.
The case will be made of steel with a high-quality coating on a CNC lathe, power will be provided through a rechargeable battery, charging via cables with a magnetic clasp.

Answer 1

Well, I don’t know about the qualities, but you can take Arduino Uno Rev3 or Arduino YUN (already with WiFi), take one of the sensors to it:
SHT75 humidity and temperature sensor DHT22
humidity and temperature sensor DHT11
humidity and temperature sensor
And take the module to Arduino Uno ( shield ):
XBee Shield or Dual *Bee Shield
C respectively Xbee Pro Series 2 with antenna and / or RN-XV WiFly module with wired antenna Bluetooth Shield v2.2 (Master / Slave )
shield weather station.
You can also screw on the screen (I advise with I2C, so the hassle is less than 4 wires)
And what is most interesting, all this usually does not work right away, you have to dig a lot on the Internet to make it all work :)

Answer 2

You can take the Arduino Nano (the most compact one) as micro. See the temperature and humidity chip here , and the WiFi chip here .
How to connect Arduino to wf chip read here .
It can be like this:
Here it is written about it
Or like this:
Read more about data transfer here .
The scheme is something like this: sensors --> arduina --> WiFi --> your software.
not the most special

Answer 3

For example, I made my own weather station - catethysis.ru/home-meteostation-stm32 - there are three articles on this topic.
The brain of the system is STM32, the sensors are DS18B20, BMP180 and DHT22, the server is Node.js. Haven't made a radio show yet. In fact, you just need to buy an STM32VLDiscovery board and flash this code there. I can post the entire project if needed. This, of course, is not an arduino in simplicity - but in fact it is also not very difficult.
I'm sure that you shouldn't be tied to Bluetooth, in my version I have almost done sending Push to an android phone simply via Wi-Fi. All indications are stored and stored by the server, and I think that Wi-Fi is much more convenient than Bluetooth.
Now a simple weather display page has been made, with charts on Flot.js: thermo.catethysis.ru
