Yves Arbour and Rui Santos describes a concept of building a weather station plus data logger using two ESP8266 modules operating in a server/client configuration. The client ESP8266 measures temperature and other sensor inputs and transmits the data to the server ESP8266, which is connected to a PC through a USB-UART bridge. This ESP8266 weather station records the sensor data to a Microsoft Excel sheet on the PC. They used the Things Gateway PC application by Roberto Valgolio to read/write data to the Excel sheets and to generate real-time graphs of sensor measurements.
