Air Quality Monitoring in Bangladesh: Use of Arduino with SO2, NH3, NO2 Sensor and Radiation Kit- A Part of Smart City Planning

monitoring the atmospheric condition is emerging as an essential issue to keep in step with progress in technology. Recently many scholars have been monitoring the real-time atmospheric condition for arising consciousness. Our device consisted of three sensors and a nuclear radiation detector connected with an Arduino board to detect the real-time environmental situation. The implementation of a device display board that is flexible and displays a detected value. The control of the sensor is based on an ATMEGA 328 microcontroller. The used ATMEGA 328 microcontroller is programmed using Assembly language through using AVRstudio software. The system consists of 16 MHz crystal, Sulfur Dioxide sensor, Ammonia sensor, Nitrogen Dioxide sensor and nuclear radiation detector. A 5V power bank is used to feed the system. The advantage of the designed device is to identify particles between 0.3 - 10 µm in the sampled air.
