Multiple low cost individual sensors communicate with a server. A proxy sensor communicates with the server. The server periodically compares information from the individual sensors with information from the proxy sensor. The server validates and accepts information from individual sensors. The server changes gain and offset values for individual sensors providing information that is not validated by the comparing.
