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 sold separately.

• RJ11 connectors for connecting wind and rain sensors (sold separately)
• HAT-format board
• Fully-assembled
• Compatible with all 40-pin header Raspberry Pi models

Notes

• Want to add on more I2C sensors? No problem, there's an solderless I2C header located on the back of the HAT that you can poke jumper / DuPont wires (or even a Breakout Garden slot) in to.
• If you'd like to hook up more analog sensors (3.3v max), some extra ADC channels are brokenout on the front of the board, as well as a convenient 3v3 power and ground.
