Introducing Weather HAT & Weather Sensors Kit - make your own Raspberry Pi weather station
Вставка
- Опубліковано 20 лют 2022
- 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 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).

The price isn't that bad too, normally the weather sensor parts are really expensive compared to getting a full weather station which you could get from maplins at the time using to same parts .
Hi, what is the easiest way to adjust the wind direction settings?
I want to mount the bar parallel to my carport. North is like 20 degrees direction „West“ of the vane.
Hi, can you please share a link to the bracket you used to mount the station outside? Thanks!
Hi. I can’t understand where the hat+rpi should be put. And how long the rj11 cables are. I’m thinking about mounting the kit outside on the balcony while having the chance to keep hat+rpi inside home. Is it possible?
Putting the HAT outside in a weatherproof enclosure or inside so you can use the screen are both valid options.
You get a fair bit of cable on the wind and rain sensors so your setup sounds possible!
How often would you have to update to get rain data? Does the HAT store any data or would I need to update say every second to get the data?
The HAT has an onboard microcontroller that collects the signals from the rain and wind sensors - more info in learn.pimoroni.com/article/getting-started-with-weather-hat ! The update interval is customisable in the library.
@@pimoroni Thank you!
@pimoroni What troubleshooting would I do if we downloaded the weather hat software for the sensor kit but it is not working. we are using the raspberry pi zero with wifi.
Please drop a post with the details on our forums ( forums.pimoroni.com ) or to support@pimoroni.com .
Around 2014 Maplin had a weather station for something like £80. Used the same parts as this to collect rain quantity, wind direction and wind speed. You were able to buy a "spare" rain sensor for something like £3, wind speed for £5 and wind direction for £10. Had a look for the wind speed sensor on ebay recently and it was something like £30! Kind of begrudge paying £30 for 2 bits of plastic, a reed switch, a magnet and a bit of wire
We remember those kits at Maplin and are pretty sure at the time they were trying to get rid of stock (hence the low price). Shipping is extremely expensive at the moment due to covid (like 10x the usual price) and since the sensors are quite large and bulky that does have a big effect right now - hopefully things will improve soon!
Can you use an external temperature sensor with the kit?
The Weather HAT has 4 IO/ADC channels exposed for your own use - they would be suitable for hooking up an external temperature sensor.
Hi, is it possible to use it with a pico w?
Weather HAT is designed for use with Raspberry Pi SBCs, but Enviro Weather is Pico W based - check out shop.pimoroni.com/products/enviro-weather !
How can you change the software to display Fahrenheit temperature?

I bought one and it's very nice. However, as it stands, I don't think it's usable for serious work, for example in a school. I've a great respect for Kevin but he's a bit thin on how to mount the weather hat outside. He suggests using a Stevenson screen, the standard metrological enclosure from the 19th century designed to prevent sunlight influencing a temperature sensor (in old school terms a thermometer). But using one will not allow the light sensor to work probably as it needs to be in sunlight. Using a tupperwear box isn't ideal either nor a standard waterproof electrical box. Each sensor really needs to be positioned in a way that allows it to take readings without being unduly influenced by external factors such as the processor temperature, enclosure humidity and light from the display. Using a "fudge factor" to compensate for the processor temperature isn't that good an answer.
If you ever do a "Mark 2" I'd like to see an option to have the light, temperature and humidity sensors remotely mounted and the ones on the board optionally disabled. It's nice that the the A2D pins have connectors on the board but it would have been handier (arrr) for the I2C bus to have been broken out, breakout garden style. This would allow the use of all those fab sensors you sell such as the BME688 I've got my weather eye on arrr.
Apologies for the lengthy comment but I've been a customer of yours for a long time and I want to see you make a good product great....
Ahoy Stephen! There's some more info about how you can calibrate your readings to allow for Pi-generated heat in our Getting Started tutorial - learn.pimoroni.com/article/getting-started-with-weather-hat . We've found having a well ventilated enclosure helps a bunch!
We're using a white 3D printed Stephenson screen for our enclosure, which does a pretty good job of letting the light through - you can certainly tell the difference between night time and day time for example, or between a sunny and cloudy day. If you're using a more opaque enclosure , you could use something like a light pipe to help light get to the sensor.
There is a broken out, jumper wire friendly I2C connector on the bottom of Weather HAT that will let you connect up I2C sensors or Breakout Garden breakouts. If you want to add a Breakout Garden slot for your BME688 you could plug one of these connectors into it? shop.pimoroni.com/products/breakout-extender
@@pimoroni thanks for the reply. I was dumb enough to not notice the I2C connector on the base of the board. It must be old age, or that I don’t usually use the breakout garden slot because I habitually hard wire sensors.
I’ll 3 D print a screen and look at light piping for the light sensor.
Thanks again for the product and the comments. Apologies for my dumb post
shame that brexit made you abandon your european store
That was due to quite a number of reasons. We have implemented IOSS and are continually tweaking the process so that shipments into the EU happen smoothly and VAT etc are all handled by us.
