Weather HAT (HAT only)
A meteorologically minded Raspberry Pi HAT designed to make hooking up weather sensors a breeze (or a squall, or a gale).
Weather HAT is a tidy 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 (remember those?) will let you easily attach wind and rain sensors. It will work with any Raspberry Pi with a 40 pin header (that's most of them except the really old ones).
You could install it outside in a suitable weatherproof enclosure (like a Stevenson screen, a waterproof junction box or even a Tupperware container) 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.
Please note: The wind and rain sensors are NOT included.

Raspberry Pi and accessories are sold separately, check out the Extras tab for some options!
Pimoroni has put together a Python library to give you easy access to all Weather HAT's functions, together with straightforward examples to help you learn how to read the sensors and use all the individual parts. There's also a weather station example that shows you how it's possible to combine all the functions into an application.
The Getting Started tutorial contains a thorough walkthrough of Weather HAT's functionality plus beginner friendly instructions for installing the Python library and running the examples.
- Want to add on more I2C sensor breakouts? No problem, we've added an I2C header on the underside of the HAT for you to connect jumper wires up to.
- Perhaps you would like to hook up more analog sensors? We have that covered too! We've broken out some extra channels on the Nuvoton chip that we use as an ADC and IO expander, as well as a convenient 3v3 and ground.
- Two standoffs at the GPIO edge should be sufficient to keep this HAT firmly in place, but if you're attaching it to a full-size Pi and want to add standoffs at every corner.
- Dimensions: 65 x 56.5 x 19 mm (L x W x H, including header and connectors).
