“Air pollution has a number of negative impacts on the environment, including damage to human health and natural ecosystems. The World Economic Forum has stated that air pollution is the ‘deadliest form of pollution’, while the World Health Organization claims that in 2016 over 92% of the world’s population reside in places where air pollution exceeds health and safety limits. Despite these unbelievable facts, some countries - like the UK, US, Australia and New Zealand - are seeing a decrease in the amount of air pollution. Although urban green spaces are not solely responsible, it’s undeniable that these areas have contributed to the overall decline.
I live on the shores of a big city, and close to an ecological reserves with natural lakes and migrating birds of all species. I developed a LoRaWAN System with the Arduino MKR WAN 1300, that help me to monitor the air quality and water ot the ecological reserve of my community. INNOVATION: I have replaced the commercial Gateway with a hardware and software solution between the Arduino MKR WAN 1300 and Arduino NANO 33 IoT, so this project is original and cheaper than any other. Now, plants receive enough quality water, and adequate nutrients thanks to real-time sensor monitoring.
How does it works?
I collect data with sensors such as: Humidity, temperature, Carbon Monoxide, Carbon Dioxide, Volatile Organic Compound (TVOC), Smoke, water level, etc;
I select and pre-program the time intervals when the system is monitored, and then it go into low consumption for energy saving;
I’m using connection via RF through Carrier frequency LoRa (433/868/915 MHz)
I read the captured data and activate alarms to be seen on an LCD screen or on a Laptop or a PC.
This system connects to the cloud of an IoT server through an Arduino NANO 33 IoT board.
