Solar Powered Environmental Monitoring Kit

A solar-powered open source kit for monitoring air quality, sound level, humidity, and temperature.

My city Dhaka (capital of Bangladesh) is one of the world’s largest cities, with a population of 18.89 million people in the Greater Dhaka Area. It is also the 4th most densely populated city in the world.

Sorry to say that Dhaka has been ranked highest in the US Air Quality Index (AQI), for having the worst level of air pollution in the world. Noise also always goes far beyond the permissible level. Sound pollution has reached the highest 120-130 decibels (dB) at many points of the city — almost double the permissible level.

To save the city it is very high time to take necessary steps. Creating public awareness is first one of the steps. For creating public awareness we need real time data of the noise we are creating everyday. If every one can see the noise level and air quality in real time it will create a mental pressure for taking steps against the pollution. Researcher will also be benefited from this open source real time data.

From the thinking I designed an open source real time city pollution monitoring device which monitors noise level, air quality, temperature, and humidity and sends the data to the ThingSpeak. I used GSM for data transmission because availability of wifi is very much limited in the city. The device gets power from a solar panel.

I tried to keep it very simple so that anybody can make his own device. No soldering is required for the device. Just collect the required components, upload the code and plug and play all the modules.

Following figures shows all the required components and modules. All the things are available in seeedstudio.com.”
