Station Creation

As the final task for the Introduction to Programming and Physical Computing course, the HPWWS (House Plant Watering Weather Station) is a small Arduino project for data-savvy plant enthusiasts. The project gives real-time data about the plant’s (indoor) climatic conditions to the inhabitant and tries to maintain a constant and optimal soil moisture level for the plant.

Station Testing

The technical build-up of the HPWWS.

The project consists of three different sensors and four actuators.

With a quick prototype of the system, the HPWWS was tested and the data was analysed to check the stability of the sensors and the overall sequence between the components.

HPWWS prototype and testing. The picture was taken after watering of the plant: Valve (servo) is closed, soil water content is at 71 (high value) and red LED indicates a lack of water in the reservoir.

Data logging on a MicroSD card allows for a review of the growing conditions of the plant. The data logging (both in the serial monitor & MicroSD card) also allows checking the stability of the sensors and their reaction time to external changes.

House Plant Watering Weather Station is a project of IAAC, the Institute for Advanced Architecture of Catalonia, developed during the Master in Advanced Architecture (MAA01) 2021/22 by student: Jett Demol; faculty: Angel Munoz, Cristian Rizzuti; Bernat Morato; faculty assistant: Antoine Jaunard.
