Proof of Concept – BioSignals

BioSignals has begun! Kim has set up a prototype IoT-based biosignal system using the Aloe Vera plant in our studio space.

 

The system configuration is:

ESP32 microcontroller

Sensors: DHT11 (temperature and humidity), Light-dependent resistor, Two x nails and a resistor to make a moisture sensor

Signal Protocol is still to be decided for the project, but this test involved a Firebase Realtime Database

The signal is being received on another ESP32 sent to a webpage.

Location: The Strand Arcade, Whangarei

Live Signals

Key to having a successful outcome for this project is the need for real-time raw data signals to be sent and received across the globe. This means generating signals for 24 hours so those in different time zones can receive and visualise during their main working hours.

Kim has set up a temporary site to experiment with visualisations. You can view it here: DATA (wiredvisual.net)

You can see the different sensors feeding data – the background image is of some prints Kim has done with local weeds using a Gelli plate.

Gelli Print Experiments

Alongside his IoT experimentation, Kim collected an array of noxious weeds from around our property: Moth Plant (Araujia hortorum), Taiwanese Cherry (Prunus campanulata) and used a Gelli print technique to create initial images.

We are still formulating which plants to use as part of our project here in NZ. We are experimenting and researching with various plants that represent resilience and are directly impacted by climate change. For various reasons, we are not using native plants in our project.

FAQ

The Internet of Things, or IoT, refers to a network of interconnected devices embedded with sensors, software, and other technologies that enable them to collect and exchange data with each other over the Internet. These devices range from everyday objects like thermostats and light bulbs to complex machinery in industrial settings.

Gelli printing utilises a reusable gel printing plate as the surface for creating prints. Artists apply layers of acrylic paint or ink onto the plate, manipulate the paint with tools or objects, and then transfer the image onto paper by pressing it down. Each print is distinct due to the spontaneous nature of the process.
