Story

A system for mobile real-time air  pollution monitoring system has been developed. This system is being developed with an aim to monitor pollution in real-time. This system uses low-cost air quality monitoring sensors with GPS and GSM/GPRS modules or Bluetooth mesh network. The concentration of various gases will be measured using the semiconductor sensors and location of that concentration using GPS module. This concentration will be measured at various locations at a real time scale. Sensors after gathering data will send data to a database using GPRS/Bluetooth module along with the location obtained. Fundamental aspect of above work is to provide a real-time dynamic pollution measurement system.

About the project

Hardware Schematic Water Density Mapping For Plants

Mapping water content in the soil of agricultural land is challenging due to variations in the field. In-order to track soil moisture content, each plant is equipped with a CYBT-213043 and capacitive soil moisture sensor forming a mesh network and the paired android app stores the data locally and popups a visual representation.
