Environmental sensors,
left in the field.

Solar-powered. No batteries to swap. No maintenance contracts. A weatherproof field instrument that streams camera, temperature, air quality, audio and solar data — for as long as the sun keeps coming up.

What it senses · 03

Five channels. One enclosure. No maintenance.

01

Camera

2MP · IR cut · 1 frame / 5 min

A wide-angle RGB sensor captures a frame every five minutes — a visual record of the landscape that complements the numeric channels.

02

Temperature

−40 to +85 °C · ±0.2 °C

A calibrated digital sensor logs ambient temperature every 30 seconds, averaged into a minute-resolution stream.

temp_c = 14.2 · σ = 0.03
03

Air Quality

PM2.5 / PM10 / VOC · MOX

Particulate counts and volatile-organic-compound levels expressed as a standard AQI. Useful in fire seasons and near roadways.

aqi = 22 · pm2.5 = 4.1 µg/m³
04

Audio

MEMS · 25 Hz–20 kHz · 16-bit

A MEMS microphone captures 1-second clips at 5-minute intervals. Anonymised sound-pressure level (dB) and spectral features are streamed; raw audio stays on-device unless opted in.

L_eq = 51 dB · 1 s clip
05

Solar & Power

Vin · W · battery state

The same channel that keeps the station alive is also data: solar input watts, battery voltage, and charge state — telemetry from the energy budget itself.

P_solar = 4.1 W · V_bat = 4.02
