The climb from branch to cloud.

Entry 01 / Probe POC

The physical object makes climate visible.

The Probe POC is the starting point: a small physical sensor that makes indoor climate, plant conditions and classroom experiments visible. It turns invisible changes in air, light and growing conditions into something people can observe, question and discuss.

The first bring-up is deliberately physical. A battery, a board, a light, a sensor and a plant on the table make the system easy to read before it becomes a cloud diagram. The object has to feel understandable before the data becomes useful.

That is also why the probe matters for KlimaLab. It can sit inside a classroom, greenhouse corner or workshop and become part of the room instead of another hidden instrument. The next step is to keep improving the enclosure, runtime and calibration so the measurements become trustworthy over longer tests.

Entry 02 / Cloud POC

The link from hardware to shared data.

The Cloud POC documents the next layer: Gateway hardware sends live measurements through NB-IoT into Firestore Cloud, where dashboard and app can read the same device-owned data. This is the proof that local sensing can become shared access.

The important part is not only that values arrive on a dashboard. The important part is the full path: a device measures, the gateway publishes, the backend validates the topic contract, Firestore stores the event, and the interface turns the stream into something a person can inspect.

This is where ARC starts to look like infrastructure. A teacher, investor or technician can open the same cloud view and see proof of life from the hardware. From here the work becomes sharper: access control, device identity, reliable command acknowledgement and a dashboard that can explain the system without needing an engineer beside it.

Entry 03 / MCU Format V2

From prototype design to format.

Version 2 of the modular MCU format has been ordered, and we are looking forward to exploring it for both lighting and motor control. The format has grown from prototype design into a reusable hardware foundation that can support multiple product directions.

The goal is a format that can carry different experiments without starting from zero every time. Power, sensing, control and firmware access need a repeatable base, so new ideas can move faster from schematic to bench test.

For lighting, the format gives a clear path toward connected power stages and controlled output. For motor control, it opens the door to FOC experiments, pump behavior and closed-loop control work. The common thread is the same: make the electronics modular enough to learn from, but disciplined enough to become a real platform.
