An automatic device that can measure and record six weather parameters has been built at Bosscha Observatory. Those six parameters: wind direction and velocity, air temperature and humidity, precipitation, and rain gauge and time-keeper, are measured and recorded periodically to a Micro SD card. The device is powered by a battery which is recharged using a mini solar PV panel. In addition to requiring precision and accuracy as normally prioritized in measurement device, our design particularly considers the economic aspect and the transparency of the inner working of the device. For the educational and empowerment perspective, it is important that all the applied scientific principles are comprehensible. Our objective is that this automatic weather measuring device, which is much needed in various open air work areas, can be easily learned and built by young technicians all over Indonesia using simple and easily available materials. We had calibrated our device to a standard commercial one and tested it in a number of places in Lembang. We plan to test this device in other areas to know the device reliability and construction strength against various weather conditions.
