Life Node at Scheerwolde, Weerribben (first Life Box site)
What the box measured and how it was doing, over time. Nothing here is modelled: every point is a post the node made. Times are local to the place (Europe/Amsterdam); the grey bands are nights. The location is shown to within 1 km.
Life index
One verdict for this place, read from three streams on one timeline. The seven readings are never summed: the weakest decides, and a stream that has not spoken yet makes the verdict insufficient, on purpose. The satellite has watched since 2019; sound and soil began when the node arrived.
Satellite: 814 clear Sentinel-2 scenes since 2019, computed here from Copernicus data. Sound: species recognised in the box (BirdNET-Go); only names leave the field. Soil: moisture and temperature from the probe at 10 cm; the activity in the readout is what the weather allows soil life to do (Q10 of 2, moisture from water-filled pore space or an optimum of 31% from the soil texture); the cycling reading takes its direction from the water roots draw on dry days (the soil's water loop), not from this. Method: the spec.
Heartbeats
Every post the box made. It posts three minutes after a start, every three hours after that, and once more when it switches itself off. A silence after a shutdown is sleep; a silence without one means a post went missing.
Soil
No soil probe has reported yet.
The box itself
From the heartbeat: the battery it runs on, how warm it is inside, and what it draws. The battery is a 12.8 V LiFePO4; under 12.8 V the last tenth of the charge is left, at 12.6 V the node switches itself off to keep it, and above 13.2 V, with the panel charging, it starts again.
Sound
What the microphone recognised. Species recognition runs in the box; only the names leave the field. The grid is the last fourteen days by hour of the day, so a dawn chorus shows as a dark column.
