Our staff is experienced and qualified to install remote monitoring equipment for a variety of applications that require general construction knowledge to interpret structural, electronic and telecommunication plans and specifications. We can also provide expertise in developing instrumentation hardware and software aspects of remote monitoring devices; we have created programs for dataloggers and interfaced sensors for automated stormwater sampling systems, including the development of input/output routines using proprietary communications protocols of manufacturers of flow meters and other devices. We have deployed, developed, and diagnosed systems that were accessed remotely using various technologies that included simple modems, cellular modems, short-haul radio modems, long distance high-gain radios, satellite communications, and Ethernet systems using the Internet. ADH has managed databases of multi-year sampling programs for numerous clients, and written analyses on the respective data. We have in-house expertise in statistics; have designed sampling programs; have run the statistical tests specified by those designs; and have written statistical sections of stormwater annual reports.
