Solar powered Environmental system

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.

Its 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.

Project Description:

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

• Seeeduino GPRS : Seeeduino GPRS is an Arduino board with integrated GPRS module (SIM800) and support GSM, Bluetooth and FM. Instead of using it you may use Seeeduino V4 and Seeed Studio GPRS Shield V3.0.
• Seeed Base Shield V2: Seeed 1W Solar Panel 80X100= 1W Solar Panel is required for charging the Battery and providing the required power for the kit. This panel is enough for delivering the power required to run the kit at least 48 hours with 4 hours sunlight. The size is important to adjust it in the 3D printed case.

• LiPo Rider Pro board: The LiPo Rider Pro board allows you ride the solar wave to run your favorite 5V device. The LiPo Rider Pro board is the ideal green power solution for your outdoor sensor design. Attach the LiPo Rider Pro board to your sensor board and it can run on solar power forever! Instead of LiPo Rider Pro you may also use Solar Charger Shield v2.2.
• Air quality sensor v1.3: The sensor can detect carbon monoxide, alcohol, acetone, thinner, formaldehyde and other slightly toxic gases. It is compatible with 5V and 3.3V power supply. The sensor is used to monitor the air quality of the environment
• Loudness Sensor: The Grove - Loudness Sensor is designed to detect the loudness of environmental sound. Based on amplifier LM2904 and a built-in microphone, it amplifies and filters the high-frequency signal that received from the microphone, and outputs a positive envelope. This will make for Arduino's signal acquisition. The output value depends on the level of sound input. It gives an analog output. I mapped the analog value to dB with a sound level meter. The output dB is not accurate enough and for testing purpose only.
• Temperature & Humidity Sensor: The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data.
• Li-Ion Battery 1000mAh: 1000mAh is required for powering the device for 48 hours assuming the data will be updated once in a minute. Capacity depends on the frequency of the data update.

Application:

1. Live time Update
2. monitor your city conditions
3. pre alert before nature activity
