S142 How Low Can You Go? Determining the Accuracy of Very Low Cost Internet Weather Stations

Two different types of personal weather stations are compared to the Texas A&M Research Farm Mesonet meteorological site and tested for accuracy in multiple parameters to determine viability and value. The tested stations are among the least expensive stations that provide all major parameters and are capable of uploading to services such as Weather Underground or the Citizen Weather Observer Program (CWOP). The two weather stations tested are the Oregon Scientific WMR-100 and the Dr. Tech WH-1080PC, each available for around $100 (U.S.). The research included testing the two stations for accuracy in a variety of situations, such as cold front passage, excessive heat, and thunderstorms. Additional tests involved the use of an optional radiation shield to examine how the shield improved temperature performance. Recommendations are also given for those wanting to invest in low cost weather stations based on factors such as ease-of-use, supplied accessories, and software options.
