The Real Time Hardware Design to Automatically Monitor and Control Light and Temperature
Dushyant Pande, Jeetender Singh Chauhan, Nitin Parihar · 2013
A smart, integrated temperature and light controlling and monitoring system has been implemented with the use of open standard technology, commercial and household items which actively monitor the environmental conditions. A main target for this system is to have it designed and implemented as cost efficient as possible. The system allows for a user to input the desired conditions regarding the surrounding atmospheres temperature and lighting requirements. This paper incorporates design and development of temperature & light monitoring and controlling system. The project consists of two modules. One is the parameter monitoring and the other one is the parameter controlling. Monitoring and controlling physical parameters like temperature and light are of outmost importance. A temperature sensor LM35 will be used for the purpose of measuring temperature and a LDR will be used for measuring light intensity. A microcontroller then compares the environmental conditions against the user's input requirements, and actuators change the settings until the desired conditions have been obtained. The controller is responsible for sensing from ADC, detection and polling of the peripherals status. A display unit will show the values of parameters like Temperature and Light. This will be helpful for the person to know the values, for this purpose use various sensors will be used, which will be connected to ADC. The device can be used for various purposes like weather forecast, industrial monitoring and green house monitoring etc.
