Our technology stack rests on four main pillars.
build our network using compact air quality monitors which stream data
to our cloud platform. Only third-party monitors that Planetwatch has
thoroughly tested for reliability and performance against reference
systems can be connected to the PlanetWatch network.
We are developing our own monitors, which will feature increased data
security and reliability (proof of data origin).
are setting up a data acquisition framework capable of receiving and
validating high-frequency data streams from thousands of sensors
worldwide. In doing this we leverage the CERN Control and Monitoring
Platform (C2MON), which is a heterogeneous data acquisition framework
with configuration, persistence, historical browsing, control and alarm
functionalities. It has been developed for CERN’s demanding
infrastructure monitoring needs and is based on more than 10 years of
experience with the Technical Infrastructure Monitoring Systems at CERN.
One of the biggest technical challenges for Planetwatch is to extract reliable air quality information out of data from a heterogeneous sensor network. We aggregate data from consumer-grade as well as high-end sensors, installed in a variety of sites, possibly including mobile sensors. This is why we need advanced AI-powered algorithms to cross-calibrate sensors dynamically and filter out outliers and spurious data.
leverage blockchain technologies to build a global, permanent,
tamper-proof air quality ledger and to track and reward all data
streams. We have chosen the Algorand blockchain because of its
unparalleled scalability and security. In addition, its Pure Proof of
Stake (PPOS) consensus mechanism also makes the Algorand blockchain a
“green” one, removing the need for computer-intensive calculations to
