Vietnam’s agricultural production depends heavily on natural conditions such as land, weather and irrigation water. Due to the impacts of climate change, the Central Highlands and the South-Central Coast region, Vietnam often suffer from prolonged drought conditions, wilting many crops such as coffee, apple grapes, pepper causing damage big socio-economy, affecting people’s lives. According to the survey results of the Central Highlands Agriculture and Forestry Science Institute (WASI), over 73% of farmers irrigate water for crops, wasting water resources and increasing production costs. Therefore, the research for advanced irrigation technology, can determine the appropriate amount of irrigation water, at the right time for each type of crop, thereby saving the maximum amount of irrigation water but still ensuring productivity and capacity increase. In this study, we will develop methods, models and designs smart, economical irrigation systems using humidity sensors to regulate the amount of irrigation water sufficiently and at the right time by solar energy. We have designed a soil moisture sensor system using wireless sensor networks technology for remote control for watering enough and at the right time to supply crops. The Soil Moisture Sensor (Soil Moisture Sensor with accuracy: 0 ∼ 50% (m 3 /m3) within ± 4% of working voltage: DC 3 - 5V. Average current 16 hours. Moreover, we have built a process of smart watering technology based on the Soil Moisture Sensor system and remote control for vine in Ninh Thuan province, Vietnam for the Vine farm 1000 m 2 . The system has been tested in reality in vine research area in Ninh Thuan province, Vietnam for the Vine farm with 1000 m 2 . The system includes automatic sensors connected to the central controller and the pump is simplified by buttons on the electrical cabinet or on the phone application, making it convenient for the farmer to operate and apply.
