Grow-Native Tent Monitor

Meet Sensi

Sensi tracks temperature, humidity, barometric pressure, CO2, light, and VOC trends right at canopy level, the readings cheaper monitors leave out. Place or hang it where it matters, connect power, and join your local network.

Precision & Quality

Built around the sensors, not the price tag.

Genuine Bosch and Sensirion sensors, tier-one Samsung and Panasonic passives, and latest-generation parts on a 4-layer board sealed in waterproof M8 connectors, chosen so Sensi meets or beats the tolerances of monitors costing far more.

Sensi monitor with a live Visual Diary display and its sensor suite: temperature, humidity, VPD, CO₂, VOC, light, and PAR/PPFD

Bosch pressure True atmospheric pressure for pressure-aware VPD and tighter CO₂ compensation.
Sensirion temp + RH Dedicated climate sensor at roughly ±0.2 °C and ±1.8% RH.
NDIR CO₂ Real ppm enrichment readings, not an estimated eCO₂ proxy.
VOC Aroma Index A digital-nose signal for run-relative smell and stress.
Precision light Calibrated lux on Sensi1; quantum PAR/PPFD on Sensi2.
Built to last 4-layer lead-free PCB, authenticated ICs, vented for honest gas exchange.

Aroma Index is directional guidance, not guaranteed diagnosis. Tolerances are typical sensor specifications; field accuracy varies with placement and calibration.

Local vs Cloud

Same app. One half never sleeps.

The app and browser look the same either way. The real difference is what keeps recording and watching when you (and your devices) aren't around.

Local

Open the app or a browser on your Wi‑Fi and read your Sensi directly: no account, no subscription, nothing leaving your network. The device runs a lightweight server that hands the latest readings to Cannalytix or your own local apps on request, and buffers a rolling window of recent history on‑chip so a brief network drop backfills on its own.

That on‑device window covers recent history, not a permanent archive. Keeping a complete long‑term record just needs something always collecting it; locally that's whichever of your devices is running the app, while it's awake on your network. Want that handled for you, everywhere, around the clock? That's exactly what Cannalytix Cloud is for.

Cannalytix Cloud

Cannalytix Cloud is the permanent, always‑on half. Your Sensi streams to it continuously, so history keeps filling and alerts keep firing even when every phone and laptop you own is asleep, updating, dead, or three states away, and even if you're gone longer than the device can hold.

And it's reachable from anywhere: check the room while you're out, share access across people and sites, recall long‑term history, and get alerted the moment something drifts, not whenever you next happen to open the app. APIs and cross‑Sensi scores build on top.

Included per our launch policy; optional paid Cloud after the included months on non‑founding hardware.

On the device, in the app, or in your browser.

Three surfaces for the same grow. Pick what fits the moment. Each works on your LAN or with Cloud, depending on what you need.

Sensi on-device display showing live environmental readings

On the device

The built-in display shows live temperature, humidity, pressure, CO₂, VOC Index, and light, no phone or laptop required.

Cannalytix mobile app with charts and grow diary

In the app

Cannalytix on your phone or computer: charts, alerts, grow diary, and Visual Diary. Connect locally (read your Sensi directly on Wi‑Fi) or sign in with Cloud for sync and sharing.

Cannalytix web interface with Visual Diary in a browser

In the browser

Full UI in a web browser on phone or laptop. Same idea as the app: read the Sensi on your LAN for local use, or use Cloud when you want history and access away from home.

Two Models

Sensi1 and Sensi2

Same precision core on both. Sensi1 tracks ambient light in lux; Sensi2 adds quantum PAR/PPFD (keeping lux for light-leak detection) and an expansion port for future add-ons.

Sensi1 in warm grow light, its display on the light view showing ambient brightness in lux — Sensi¹

Core environment sensor with temperature, humidity, pressure, VPD, CO2, and VOC-based Aroma Index, plus precision lux light tracking.

Starting at $159.

Sensi2 with its display on the light view showing quantum PAR/PPFD in µmol/m²/s, side expansion port visible — Sensi₂

Everything in Sensi1, plus quantum PAR/PPFD light sensing (with lux retained for light-leak detection) and an expansion port to grow the stack later.

Starting at $299.

How Sensi Compares

The most complete instrument in its class.

These are all serious, scientific-tier monitors built on premium, top-brand sensors; this isn't a comparison against bargain gadgets. The difference is how much Sensi includes at each tier: real CO₂, barometric pressure, and a VOC aroma signal come standard, even on the entry model.

1 Computes VPD and dew point using actual measured barometric pressure for higher precision. 2 Computes from estimated elevation/pressure (no onboard barometer). 3 Buffers readings during outages but requires the vendor cloud/app for normal use.
