The Gen5 Sentinel
One device. The whole environment.
Most monitors read a metric or two. The Sentinel packs best-in-class sensors into a single compact, wireless unit — then layers AI on top to understand what the numbers actually mean.
- AI-powered sensingVape, cannabis & cigarette detection · noise & partying · occupancy — the moment it happens.
- Wireless & flexible802.15.4, Zigbee, 900MHz, WiFi, Bluetooth & satellite. Deploy anywhere in minutes.
- Add sensors any timeFormaldehyde, CO, NO₂, O₃, ammonia, radiation, thermal, 4-20mA industrial bridge and more.
- No-code deploymentProvision, map and monitor from the Aretas IoT Cloud — no integration project required.
AI-powered insights
AI is the foundation of everything we do: real-time detection, predictive forecasting and anomaly detection turn raw data into decisions you can act on.
Unrivaled cost / value
The same enterprise-grade sensing and analytics as premium providers — at a fraction of the cost. End-to-end, from device to dashboard.
The IEQ difference
We measure what others can't.
Competitors stop at air quality — temperature, humidity, CO₂, particulates. Aretas reads the full Indoor Environmental Quality picture, so you understand comfort, safety and behaviour.
🔊Sound & Noise
40–120 dB SPL with FFT, spectrum and AI sound classification.
💡Light
188 µLux to 88,000 Lux — plus PAR / quantum options.
📳Vibration
Vibration, acceleration and angle for structure & equipment.
👥Occupancy
Real-time presence & occupancy detection for space utilization.
👃Odor
Multipixel odor sensing + AI that classifies 60+ scent signatures.
🌫️Air Quality
CO₂, VOCs, PM1/2.5/10, formaldehyde, ozone, CO & more.
AI at the core
It doesn't just measure. It understands.
Models trained on every sensor in a device score incoming data in real time — and now the cloud reads your whole building and writes you the morning briefing.
Daily AI briefing NewEvery morning, AI digests your building's stats, alerts and rhythms into a plain-language brief — with suggested actions.
Ask your building New"Why is room 204 stuffy in the afternoon?" Ask in plain English; the AI queries your live data to answer.
Smoke & vape detectionCatch cigarette, cannabis & vape events in the act — with evidence for chargebacks.
Anomaly detection NewRhythm models learn what normal looks like, hour by hour, and flag what doesn't belong — no thresholds to babysit.
ForecastingSee CO₂, temperature and more hours ahead — overlaid on any chart.
Noise & partying detectionFlag noise violations and gatherings before they become complaints.
Occupancy detectionUnderstand how spaces are actually used, room by room.
Odor classificationCustom-trained models recognize 60+ scent signatures.
