Well we finally got our\u00a0Outdoor Weather Station out the door, it has been a background task for quite a few years but came to the front after a number of inquiries came in. Our talented mechanical designer Xiaoni at the office here has been doing iteration after iteration on the 3D printer, the design had been getting more & more mature and then…. everything changed. We found the tooling for the radiation shield on a Chinese web site, all the hard work is done for us. Nice. Our duct humidity probe just so happens to fit right inside this shield so we’re set.<\/p>\n

As usual clients are already asking for variations and we’ve since added a light sensor… another client is asking about wind speed & direction, another doing outdoor particle measurements and sound level. The design for these options is\u00a0 under way and we’ll have to do our own tooling to handle all these options but as usual I am game to get involved in interesting projects.<\/p>\n

The weather station has both an Ethernet port AND the RS485 port, plus it supports both Bacnet and Modbus on each of these ports so there’s plenty of ways to connect.<\/p>\n

The Enthalpy and Dew points are calculated from the temperature and humidity readings which helps if you’re doing free cooling strategies.<\/p>\n

Parameters: Temperature, Humidity, Light, Enthalpy, Dew Point.<\/p>\n

And here’s a nice graphical ‘Psych Chart’ interface we’re\u00a0 working on to help the building operator optimize,\u00a0 see problems and generally get a better feel for where their system is operating. This psychometric tool is free and open source, contributions are appreciated. You can clone the repo from here:<\/p>\n

And while we’re at it, here’s the repo of the source code for the outdoor weather station itself. The same PCB is used for many models of products so the title of the project is a little misleading, this is the source code for the weather station project as well.<\/p>\n
