Manoj Kumar, Neelu Jain . Design and Development of Handheld Solar Powered Air Quality Measurement using LoRa. International Journal of Computer Applications. 174, 25 ( Mar 2021), 22-27. DOI=10.5120/ijca2021921161
Abstract
This paper discusses design and development of portable solar powered air quality measurement device using LoRa technology. It uses RTC and GPS which allows the system to identify when and where the data is been recorded. In this paper, main objective was to focus on making system self-powering, along with displaying the measured quantities on the sensor node and sending to the receiver node. This work also focused on making a system which can measure indoor and outdoor AQI as well. It has been tested and verified with the data measured by “aqicn.org”. It is a low power consumption device which can also be powered by a standard USB. The device is able to transmit the data up to 7 Kms with the RSSI of -128dBm in urban areas and can be deployed for measurement of AQI. The device can also be used as mobile AQI measurement device, as it is fitted with GPS and RTC through which it can determine when and where the AQI is good or bad.
