Engineering Students Create Automatic Sprinkler System with Spider Sensor

Vast technological advances coupled with monotonous routines can trigger boredom that leads to stress. To rest oneself from this burnout, some people choose to switch to gardening or farming.

Based on a study published in the Journal of Health Psychology, it is explained that farming is more effective in reducing stress than reading books.

Another study in the Journal of Public Health also said that just working in the garden for 30 minutes can improve self-esteem and mood.

Therefore, some people decide to have a small garden in their house to refresh their minds. With a garden, they will try to taking care of it, watering, and maintaining their garden.

However, usually it only lasts for one to two months, due to the laziness and lack of focus and energy to care for the garden as a result of busy and increasing activities.

Facilitating the community to care for their garden at home, APPINDERS (Automated Sprinklers with Spider Sensors) was created.

APPINDERS is an automatic sprinkler system created by three students of the Faculty of Engineering, Universitas Brawijaya (FTUB); M. Roy Ali Saptura (Industrial Engineering 2017), Ilma Visi Rahmani (Industrial Engineering 2017), and Ifah Dea Hapsyari (Electrical Engineering 2018).

Supervised by a lecturer in Industrial Engineering, Wisnu Wijayanto Putro, ST., M.Eng., the team considered and fixed deficiencies in the existing automatic watering system; digital water timer (time based automatic sprinkler) and Arduino based automatic watering system.

APPINDERS itself has a more modern system and mechanism. APPINDERS uses solar panels as its energy source. As the name implies, APPINDERS is an automatic watering system using a spider sensor.

The spider sensor in question is a soil moisture sensor that is designed in such a way that the design topology resembles a spider web.

APPINDERS has a sprinkler mechanism that can move up and down automatically to adjust the location of plants that indicate a lack of water content.

When the soil moisture sensor detects dry soil, APPINDERS will move its nozzle according to the height needed to be able to reach the soil location.

This tool is designed to be as flexible as possible to make it easier for users to place APPINDERS in their garden. Besides that APPINDERS has a minimalist design. So that it can add to the aesthetics of a garden.

“APPINDERS will automatically water the plants when the soil around the plants is dry or the moisture content decreases. So we hope this tool can replace conventional plant sprinklers with more efficient and effective results,” said Roy as Team Leader.

For now, APPINDERS is still focusing only on a small scale, such as in a house garden. In the future, it is hoped that it can be developed for urban parks, educational institutions, and others.

This innovation is one of the nineteen innovation by Faculty of Engineering Student Creativity Program which will compete at PIMNAS XXXIII next November. (mic)
