Through our collaboration with Bosch, Zubie’s smoke detection works by considering the following parameters:
Particle detection
The device can detect the smoke of a cigarette, vaping device or similar products by measuring an increase of particle levels in the vehicle for at least 30 sec.
The device can distinguish between different sizes of particles and therefore identify particles that are typical for smoking.
Comparison of particles detection to background air quality
The device frequently examines the air in the vehicle and establishes the background air quality. This enables us to consider changes in the air quality outside of the vehicle when determining whether smoke has been detected.
The increase of particles must be significant to be considered a smoke event.
Duration of the event
If several smoke events happen in a timeframe of 10 minutes, they are summarized into one event.
Additional considerations
Any person smoking in the vehicle can trigger a smoke event. This is not limited to the driver only.
After detecting a smoke event, Zubie provides smoke event data to the fleet owner, but neither implies any actions towards end-customers nor gives decision-making advice.
The smoke detection device cannot identify the number or identity of people in the vehicle.
Based on the provided smoke event data in connection with timestamp and license plate, the fleet owner can map the information to the respective end-customer or assigned driver.
How to read the event data and the smoke graph?
The blue line shows the number of particles detected throughout the smoke event.
The green line shows the background air quality before, during, and after the smoke event. Background air quality represents the quality of the air measured before the detection of the smoke event.
The background air quality is typically expected to be close to 0.
