The CleanSpace Tag incorporates a carbon monoxide sensor; integrated temperature sensor; Bluetooth Smart (BLE) to connect to the smartphone; and Freevolt enabled Harvester – GSM & WiFi. The tag connects to the smartphone via Bluetooth and sends carbon monoxide levels to the CleanSpace app. Click to enlarge.

The data will feed into the Air Map, an interactive map that will show the pollution levels at the location of each courier, in real time. With the couriers predicted to travel more than 17,000 miles across London each month, the amount of indoor and outdoor air pollution data collected will be on a scale that has yet to be achieved.

The collected data is anonymized and fed into the CleanSpace mobile application allowing users to view their exposure to air pollution.

The LoRa trackers will track the location of the Gophr couriers via satellite without having to use mobile location based services which drain battery life. This provides more accurate readings on the move, with the need for fewer access points to cover the whole area of a city.

The CleanSpace Tag is the first product to be powered by Freevolt, a technology launched by Drayson Technologies that harvests and recycles wasted wireless signals to power low-energy devices so their batteries never need changing. (Earlier post.) The Freevolt harvester comprises a multi-band antenna and rectifier, which is capable of absorbing energy from multiple RF bands at almost any orientation.

Gophr and Inmarsat are the first partners announced in Drayson Technologies’ plan to create the world’s most advanced air pollution map of a city. Further organizations, groups and individuals will be equipped with CleanSpace Tags in the coming weeks and months in order to collect data, gather insights and help address the issue of air pollution in the capital.
