Zephyr is a lightweight, compact and low-cost continuous air pollution monitor that measures a wide range of harmful gases and particulates.
Zephyr Features
Cartridge system
Zephyr’s pollution sensors are located within removable cartridges, allowing a Zephyr to be highly configurable and easily recalibrated.
Near-real time monitoring
Zephyr measures air quality continuously, uploading the recorded data to the cloud every 15 minutes to provide near-real-time pollution data to the web. Zephyr can send us measurements by cellular data or Wi-Fi.
Adaptable power
Zephyr can be powered by mains or solar panel. The battery life of up to 5 days allows for Zephyr to be used for periods of unpowered mobile monitoring, such as on foot or by bicycle. We also offer an off-grid battery solution with solar charging capability for long-term deployments without mains and sporadic sunlight.
Zephyr Applications
- Identifying pollution hotspots
- Establishing baseline ambient conditions
- Studying nuisance effects of local emission sources
- Evaluating the effectiveness of pollution lowering initiatives
- Establishing city-wide sensor networks & smart cities
- Automatically control integrated systems with pollution data
- Create and configure alerts for individual or whole networks of Zephyr monitors for pollutants, meteorological conditions and monitor status. Stay informed of pollutant exceedances to help with decision making and minimise exposure.
