PLC based weather station for experimental measurements

Monitoring the lower layers of the troposphere by observing the signals of BTS base stations requires additional weather measurements. It was decided to build an experimental weather station for purposes of comparison and evaluation of experimentally obtained data from radio frequency measurements. A PLC based implementation was chosen due to its ease of operation and possibility of simple future expansion. It consists of a control PLC with connected meteorological sensors such as air temperature and humidity, pressure, dew point, anemometer, rain-gauges and others. Weather station lot was built with regards to WMO standards as a fenced area with meteorological masts and electrical boxes for power and control circuits of the weather station. After one year of operation, it is clear, that the weather station serves well and supplies with required additional measurements for the radio frequency measurements.
