Sensly is a portable pollution sensor capable of detecting the air pollution levels using its onboard gas sensors to collect information about the various gases present. This information can be fed directly to your smartphone for real time push notification updates. Sensly uses industrial sensors that assure an accurate reading of the office, home, or work environment and can be powered by either a battery or from the mains using a micro usb lead. Being aware of this data helps you to take action and bring the pollution levels down around you.
Sensly uses Raspberry Pi to manage the device and for educational purposes.
