In this research, two prototype measuring instruments were built for two different measuring parameters: an anemometer and rainfall integrated with IoT. The built sensor system can work well with consistent and real-time data presentation. The prototype anemometer built has a good level of precision but relatively low accuracy where the coefficients of determination are respectively R%u00b2 = 9x10-6, R%u00b2 = 0.1634, and R%u00b2 = 0.0239, with a percentage difference in relative values of 21.29%, 25.14%, and 25.46%. The TippingBucket Rain Gauge Prototype in measuring rainfall has quite good measurement accuracy with a measurement accuracy percentage of 95.55%.Keywords: IoT, Anemometer, Tipping-Bucket Rain Gauge, Dry Land, Precision Agriculture
