This page refers to commercial and kit weather stations. Complimentary pages include suggestions for assembling your own sensors and custom monitoring station, and systems using the Dallas Semiconductor 1-Wire technology. Please see the links at the bottom of this file.
|There are a number of
approaches to acquiring a weather station or other monitoring system, as you can see on
the following web sites. You can purchase ready-made weather stations to measure
most parameters, you can build kit projects, or you can start at the bottom and build your
own, adding the specific sensors you need as you figure out how to implement them.
By building your own, you can configure just what you want to have in your station.
Each approach has its own advantages and disadvantages in terms of cost, complexity and in
the flexibility of adding additional sensors.
If you are a neophyte in this area of environmental monitoring, it would be useful to review each of these sites highlighted below to get a feel for what's available, and perhaps shake down the direction you would like to follow.
If you have no experience in building electronic equipment (and figuring out how to make it work), then you are probably better off to purchase a complete station, ready for installation. If you have the inclination to build something and (usually) to save some money, then a kit weather station or individual sensors may be for you. A lot depends on how much you know or are willing to learn about building instruments, analog and digital electronics, and in some cases the programming of microcontrollers. How much knowledge, building skill, time, enthusiasm and money do you have ? Only you can judge these factors.
Do the available station designs do everything you want to do ? Bear in mind that it may be difficult to hook up additional sensors to some commercially-available weather stations and to station kits.
If you would like to check out the popular brands of ready-made stations, Have a look at the popular Peet Brothers and Davis Instruments. There are other brands, and check with Radio Shack - they have a variety of weather-related equipment available in US outlets.
Peter Anderson, KZ3K, is Associate Professor of Electrical Engineering at Morgan State University in Maryland. He offers lots of neat kits at attractive prices relating to microcontrollers and their applications for monitoring and control, including two versions of weather stations - one PIC-based and the other using a Parallax Basic Stamp II as the controller. The Basic Stamp design is not fully implemented (but what has been done so far is very useful). His weather stations use some sensors (anemometer, wind direction assembly, and rain gauge) from Fascinating Electronics. See the Sensors file (link below) for Fascinating Electronics sensors kits.
WeatherStamp (Basic Stamp II based) Weather Station also uses some sensors
from Fascinating Electronics.
Another manufacturer has stepped
into the breach .....
Another possibility to think about is to get the Dallas weather instruments kits and do not use the 1-Wire electronics, but to adapt the anemometer/wind vane unit and other sensors to other pickups and controllers.
Here is a threaded mail archive/discussion on 1-Wire implementation problems and solutions.
Here is an implementation of a Dallas 1-Wire weather station for APRS by Will, N0XGA, and Russ, KB0TVJ (wind direction and speed, plus temperature; they are thinking about barometric pressure). The authors feed the output to a controller (Motorola 6808). TAPR has a kit available for the controller/display.
Fascinating Electronics - These folks produce quality kits for various weather station sensors, including a rain gauge, anemometer, wind direction indicator, temperature and humidity module, and so on. They also have a weather station control and display module for sale. FE's wind direction indicator uses a dual-wiper potentiometer, which they offer as a separate module. This pot can be used for many position indication applications such as radio antenna altitude and azimuth position angles. It comes in regular and sealed (for outdoor use) forms. FE also offer the Humidity sensor separately from their T & H sensor kit.
