Node One

Daj się poznać / Get noticed – summary

Time is almost over but we have so much more work to do! Of course, we won’t stop our work but let’s summarise was has been done during competition.

The main goal was to build a control node that can gather and display information from different sources/sensors. This node is the Doton project.


But before we could create it we have to do two other projects: a GfxLCD python library, NodeOne sensor and improve one: NodeMCU boilerplate. So, in fact, we have done four projects 🙂

Doton the Control Node – part 1

We may now return to the main task, the Control Node with all data from all sources. We will present data in form of a tile.
I’m thinking about creating widgets for both Node One sensors.
Each node is the one tile. We could present light and movement with small icons and humidity and temperature with numbers. It sounds nice and simple but there is a catch. If we refresh the whole screen it would take around 5s to change its content. So we must find a way of repainting only required parts of the screen.

Part 2 – weather widget
Part 3 – window manager

Node One – a multi-purpose node

Today we combine the power of HLK-PM01, PIR HC SR-501, DHT11 and a light detector.
Together they create a nice looking multipurpose Node One. I wanted to do it for some time but the last piece was missing. I didn’t have an idea how to create a box for components.
Few days ago I found a perfect case named Z27. It has all I wanted, socket, plug and enough space for NodeMCU v3.
