<p>The present invention belongs to the field of monitoring of air quality of the environment. The invention presented herein is a low cost smart device that automates the monitoring of the dust particles present in the air of surroundings. This invention comprises of a microcontroller module, a display unit, a wi–fi module, an alarming module, and an infra red dust sensor. The invention is especially effective in detecting very fine particles in size of 0.01micron–2.5 micron. Measured dust particle is calibrated into (mg/m3) unit, which is shown on the display module attached. If the amount of dust particles is beyond the threshold level a warning message appears on the display module. An alerting system also gets activated to notify about the probable harm and discomfort. The wi–fi module periodically sends the measured value of dust density to an Internet of Things based cloud platform for storage. The user can monitor the real time data over the terminal connected to this Internet of Things based cloud at any time, any where provided the internet connectivity is available. User can later on perform statistical analysis on the extracted data from the cloud, if required.</p> |
