Simple and Cost Effective Environment Monitoring System
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 2
Abstract
Monitoring Environmental factors such as temperature measurement, light intensity, relative humidity and air composition are not only important for industrial purposes but also a cause of growing concern in our day to day life. This paper documents a construction and working of a very simple, easy to use and cost effective Environment Monitoring system which runs on battery power. It is a basic model that monitors temperature in “Celsius” and Light Intensity in “Lumens”. It starts working as soon as it is switched on and continuously shows monitored data on a LCD screen and refreshes itself every five seconds. The main objective this project is to construct a simple and effective environment monitoring system for both industrial as well as day to day use for people. It uses two sensors which are LM35 IC for temperature monitoring and Voltage divider circuit of LDR for Light Intensity measurement. It also uses Arduino Uno board which has ATmega328 microcontroller for its functioning. Arduino acts as an interface between the sensors and LCD screen. This project is successfully implemented in hardware and works excellently. The temperature readings are precise and light intensity in lumens is accurate with a negligible error of ±10%. The system is cost effective as it uses very cheap sensors, is easy to make, highly portable and compact. This is highly beneficial for low cost industrial applications, travelling situations, outdoor conditions, basic military purposes and household applications.
