Potenza offers low cost air quality monitoring system for buses
By Jim Gibbins - 1st October 2019
UK - A new CO2 monitoring system for inside the bus has been developed by Potenza Technology Ltd of Coventry, UK. The system has been installed on a new protype all-electric low entry city bus developed as part of CELEB (Cost effective ELEctric Bus) a consortium of British companies and Agrale Argentina, which is due to go on trial in Q1 2020 - see article in this issue.
The CO2 monitoring system uses Potenza’s Ethernet over Powerline system, allowing sensor modules to receive power and communicate over the same wire, greatly reducing material and labour costs of manufacture of a bus. Each sensor module has a simple 24V power connection, onto which it overlays Ethernet packets at radio frequencies. Any other device connected to the same power source can see these packets in order to form a network used to send useful data to the driver’s screen; all via the single power wire.
