From the project

Outdoor environmental monitoring system built on a Raspberry Pi Pico W. Sensors are read every 30 minutes, uploaded over WiFi to a FastAPI server running on a Raspberry Pi, and displayed in a browser dashboard.

Remote access via Tailscale VPN — no port forwarding, no auth layer needed.

All sensor fields are nullable — unconnected sensors send null.

The PCB carries two independent SPDT relays (K1 on GP10, K2 on GP15), rated 230 VAC / 5 A with reinforced insulation to the sensor side, as a hard minimum. Both relays can be switched and scheduled from the dashboard, and local sensor rules can…

Sensor projekt-V2: common questions

What microcontroller does the Sensor projekt-V2 use?

The Sensor projekt-V2 is built around the SC0919, from the RP2040/RP2350 family.

How big is the Sensor projekt-V2 PCB?

The Sensor projekt-V2 measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sensor projekt-V2?

55 components, from 31 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Sensor projekt-V2 design files?

From the CustomStuffs/sensor-projekt-V2 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Sensor projekt-V2 design in my own project?

The repository has no license, so all rights stay with CustomStuffs. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Sensor projekt-V2 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
