We report on a cost effective, portable urban air pollution monitoring device, Envirobat, based on commercially available gas sensors. In order to carry out air pollution monitoring over an extensively large area, the device integrates inexpensive solid state sensors, along with GSM Module which transmits measured data at multiple ground sites to a centralized server through GPRS. This device facilitates rapid dissemination of information on pollution levels at multiple ground sites simultaneously. The device has the capability to sense location, atmospheric pressure, temperature, humidity, CO2, CO, SO2, NO2, and O3. The device is validated through calibration and deployment for indoor and outdoor sensing applications. |
