Public micro mobility services (bikes, e-bikes, e-scooters) have a direct impact on the environment and the low-carbon economy. In parallel, sensing/monitoring urban air quality is a known need for any smart city to raise population awareness on health risks. ERMES is a technology transfer experiemnt project, supported by H2020 Smart4All aimed at improving the functionality of the air quality sensor kit of Cyclopolis to be safely mounted on public micro mobility fleets. It is enhanced with LoraWAN connectivity by exploiting the LoRaWAN@NOI network (https://lorawan.beacon.bz.it/) and will reduce the power consumption of the sensor kit. The system benefits of the the open source Chirpstack project and the data collected are going to be stored on InfluxDB, shared through and open RESTfull API. ERMES will provide the public shared mobility market with a reliable data and information service for smart cities.
