Item type:Item, Small gardening robot with decision-making watering system(2019-01-01)Tangtisanon, PikulkaewAt present, people who live in the countryside tend to move downtown in order to get jobs. As a consequence, only elders and children live in their hometowns with plenty of land left uncultivated. The aim of this research is to build cheap small gardening robots to help people grow plants in small yards as a hobby via a long-distance communication system. In this research, two robots composed of Raspberry Pi and ESP32 microcontrollers, which are low-price controller boards and convenient to buy within the country, were constructed. The robots can be controlled from long distances using Android smartphones. The capacities of the two robots with the two types of microcontroller are compared and discussed. To measure the soil moisture content, two types of moisture sensor, which are capacitive and resistive sensors, were implemented in this project. There are two main functions of the proposed model, which are weed cutting and watering plants. Moreover, a decision-making watering system was implemented and connected to moisture sensors and sprinkler controllers placed in the user’s garden. The robots were placed in the northern region of Thailand, while the user stayed in the central region and remotely controlled them with a smartphone for three months. The results show that the automatic watering system is better than a manual watering system since the plant growth rate for the automatic watering system was 20% higher than that for the manual watering system. - Some of the metrics are blocked by yourconsent settings
Item type:Item, Telecare application and tools for older adults(2015-01-26)Tangtisanon, PikulkaewRecently, with the innovation of modern medical technology, the elderly population has been rapidly increased than before. In the past, without the Internet technology, the elderly must spend their life in the nursing home even though they are not in any serious sickness due to the expensive wage of the personal curator. Fortunately, nowadays, the capability of mobile phone and the quality of networking have been improved. With the proposed model, the elderly health care strategy is changed. To begin with, the questionnaire has been carried out to the caretaker of the elderly. The result shows that almost all of them would like to tend the elderly at home if these three major problems; falling, medicine taking, and monitoring, can be solved. In this paper, not only the senior patient can recuperate at home safely without home health aides but also, this new model runs with everyday technologies and low-cost equipment such as Smartphone. The falling is detected with an integrated tri-axial gyroscope and the alert will be sent to the caretaker via the Internet. The medicine taking problem is solved with the medicine box that can be controlled by the caretaker in a remote distance. Lastly, the monitoring application is developed.
