Automatic plant watering and time-lapse
With this system, you no longer have to worry about your plant running out of water. Using a humidity level sensor, its water level will be monitored every 30 minutes and, if necessary, an extra spray will be given! The system also publishes all its measurements made thanks to the BME280 sensor in a site…

Irrigation system with solar panels
In this project we see the development and construction process of a solar-powered irrigation station. This also collects atmospheric data and soil moisture and sends them in real time to the cloud for remote monitoring, also independently controlling irrigation via a drip irrigation system, in order to keep the plants happy and within an adequate…

A smart chair that reduces the stress of sitting in the office
When designing and building projects, we probably find ourselves sitting much longer than we should, which poses a problem. Poor posture leads to all kinds of health problems, including back pain, limited circulation, and even headaches. A team of students from Tohoku University in Japan wanted to solve this problem by creating a new type…
