PlanetWatch is a French company that utilizes advanced technology and direct public participation to improve global environmental monitoring and help protect public health.Our current focus is on air quality. We are establishing a global network consisting of outdoor air quality sensors and environmentalists (PlanetWatchers). Some sensors are installed and managed by local residents, and PlanetWatch collaborates with transportation and telecommunications companies, local authorities, and others to install additional sensors. This method enables us to quickly deploy low-cost, high-density air quality monitoring networks, filling the data gap in government networks.The sensor data is recorded on the Algorand blockchain, creating a global, decentralized, and permanent air quality ledger.PLANETS is a practical token issued on the Algorand blockchain. All sensors that transmit valid data to PlanetWatch can receive PLANETS token rewards....
