== What else to buy ==
You can buy just the Pi, which is just a circuit board, or a kit that includes other components. Generally buying as a kit is cheaper than buying items individually.
You will need a micro-SD card (preferably class 10, the class number indicates the relative speed of read/write compared to original design, so this class is 10 times faster). I won't mention manufacture names here, but one well known brand (that uses descriptions like extreme) is the market leader and does have greater reliability than cheaper imitators. The card needs to be at least 16 GB as the installation takes up half of that, but you might prefer to install a 32 GB or 64 GB (or add an external drive or USB memory stick) if you intend to keep a lot of data on the Pi. You can buy Micro-SD cards in these capacities with NOOBS so that on first boot they actually install Raspberian onto your Pi.
This obviously depends on your PI model and on your weather station connection type.
You may want to buy a case, that will protect your Pi from accidental damage. A case specifically designed for your Pi model will have cut-outs in the right place for each interface connection, and will have sufficient ventilation for the electrical components to not over-heat.
You may need a power supply. This could be an official Raspberry Pi power supply. Alternatively, any power supply unit that has a micro USB connector will do, the power consumption of a Pi (whichever model) is fairly small, but it will be powered on 24/7, so a low power consumption ‘switched mode’ type is preferred – i.e. one that does not become warm when plugged in with nothing attached. You may have a suitable one left over from an earlier mobile phone. Some designs have additional holes for peripherals to be attached.
You may need to buy connection leads. You may need a HDMI lead to connect your PI to your TV or a spare computer monitor. You may need a USB lead to connect to your weather station (the Pi model Zero requires a micro USB, the Pi model 3 requires a standard A end USB) and your station probably has a USB A end connection. If your weather station connects by Ethernet, you will need one lead to connect the station to the router and possibly another to connect the hub or router to the Pi.
