Weather HAT is an all-in-one solution for hooking up climate and environmental sensors to a Raspberry Pi. It has a bright 1.54' LCD screen and four buttons for inputs. The onboard sensors can measure temperature, humidity, pressure and light. The sturdy RJ11 connectors will let you easily attach wind and rain sensors. It will work with any Raspberry Pi with a 40-pin header.
You could install it outside in a suitable weatherproof enclosure and connect to it wirelessly – logging the data locally or piping it into Weather Underground, a MQTT broker or a cloud service like Adafruit IO. Alternatively, you could house your weather Pi inside and run wires to your weather sensors outside - making use of the nice screen to display readouts.
