Voi is increasing the V4 e-scooter with an air high quality sensor

Voi has launched Voiager 4 (V4), an electric scooter with intelligent sensors that measure noise and air quality on roads.

The air quality sensor measures various particles of different sizes in the air, including organic compounds or even humidity levels.

The noise sensor measures the sound level around the scooter in decibels.

The data recorded by the sensors is processed via Voi’s Internet of Things (IoT) hardware.

In a blog post, Voi says it will be able to see the location of the scooter whether it’s been on the move or static, and provide information about air particle levels with an accuracy of less than a meter.

Over time, Voi has data from all areas of the operating area so that areas of high and low noise and air quality can be located.

The company can then share this data with its partner cities and researchers who want to use it for projects or strategies to build healthier cities.

The scooter’s safety features also include audible alarms and indicators to improve visibility for vehicles and pedestrians, including those at risk.

According to Voi, turn signals offer a 360-degree view and allow drivers to safely communicate their intended maneuvers.

V4 has a number of indicators on the handlebars and a second on the lower rear of the scooter. Users can turn on the indicators with a button on the right side of the bell while holding the handlebar. There are also two flashing indicators in the display area to indicate to the user that the indicators are enabled.

It is expected that the connected control node of the scooter enables precise positioning.

To improve location accuracy, the IoT compensates for lost or degraded GNSS satellite signals (Global Navigation Satellite System).

According to Voi, the IoT uses dual band GNSS (L1 and L5 bands). By comparing and averaging the two signals, positioning errors are minimized, as each signal can be influenced differently by urban features such as tall buildings or trees or by atmospheric disturbances.

It also accesses corrections from Egnos (European Geostationary Navigation Overlay Service) provided by the European Space Agency.

When pure GNSS positioning is difficult or impossible, the IoT combines information from various sensors to calculate the current position of the scooter.

Drivers can unlock the scooter with a smartphone, smartwatch or transport card using contactless NFC (Near Field Communication) technology.
