Cellular Connectivity: Deploy Anywhere, Instantly
- Out-of-the-Box Mobile Data: Built-in SIM connectivity lets you deploy instantly in remote locations or rental properties without needing tenant Wi-Fi credentials.
- Secure & Uninterrupted: Avoid the security risks of shared commercial networks and maintain reliable data uptime independent of local internet outages. (Optional Wi-Fi and Bluetooth are also available).
Comprehensive Multi-Parameter Monitoring
- Granular Particulates: Tracks PM0.3, PM1, PM2.5, and PM10 across four distinct size classes.
- Advanced Gases (CO2, TVOC & NOx): Features precision NDIR CO2 sensing alongside TVOC chemical vapor detection and NOx (nitrogen oxide) monitoring for combustion and traffic sources.
- Comfort Tracking: Precision Sensirion chips monitor ambient temperature and relative humidity.
Key Performance Features
- Industrial-Grade Components: Utilizes named, industry-standard hardware including SenseAir NDIR CO2 sensors and Sensirion SGP41 VOC/NOx chips.
- Open-Source Hardware (OSHW): Built on open firmware for complete transparency, full data ownership, and easy integration with Home Assistant or custom APIs.
- Continuous Stationary Operation: Designed for round-the-clock compliance monitoring and data logging powered via wired USB-C.
Frequently Asked Questions
Do I need Wi-Fi to use this monitor?
No. The Cellular/SIM Edition transmits data over mobile networks out of the box. Wi-Fi and Bluetooth remain available as optional alternative connection methods.
What makes this different from a typical consumer air quality monitor?
It tracks a broader pollutant suite—including NOx, which most consumer devices skip—uses named industrial sensor modules, and runs on open-source hardware and firmware.
Can I integrate this with Home Assistant?
Yes. The monitor is fully compatible with Home Assistant and provides an open API for custom dashboard building.
Is this monitor portable or designed for permanent placement?
It is engineered for continuous, stationary operation on wired USB-C power, making it optimized for fixed deployments rather than room-to-room portability.
Who is this monitor best suited for?
Property managers, schools, commercial building operators, and researchers who require reliable data streams independent of local Wi-Fi infrastructure.
