As the Internet of Things applications become more widespread, we face the need to replace existing implementations with Internet-enabled sensors. However, these sensors often provide worse battery life, have higher costs per unit and are not backward-compatible with existing weather stations. This paper concentrates on the possibility of decoding the weather station data by a cheap device which would forward them to the Internet of Things frameworks. The basics steps of receiving and decoding of the wireless weather sensor data are discussed together with the common problems which are associated with their capture and processing.
