Setiyono , Budi and Sumardi, Sumardi and Harisuryo, Rafdito Measurement system of temperature, humidity and air pressure over 433 MHz radio frequency: An application on quadrotor. 2015 2nd International Conference on Information Technology, Computer, and Electrical Engineering (ICITACEE) .
Gathering information of weather parameters such as temperature, humidity, and air pressure in a particular place and time as quickly and as possible are required to support other areas. However, sometimes geographical constraints such as the natural contours of the Indonesian archipelago with the ocean, mountains and hills can hamper collection this information. Therefore, we need a data collection system that can handle the problem without the influence of geographical constraints. One solution is the telemetry system. In this research, weather data acquisition system was designed with BMP180 sensor to collect air pressure data, DHT11 sensor to sense temperature and humidity data, and Arduino microcontroller used as data processing. Transmission system used 433 MHz RF module with 17 cm cable antenna as the sender and receiver of data. Data is displayed in a graph in server. So we get the data acquisition based on Graphical User Interface. Experiment results showed that the increase in temperature tends to be accompanied by a drop in air pressure, and vice versa. However, the air pressure data tend not affected to this changing the height of an area measured from sea level.
