In this project, uses two sensors, two relays, ADC (Analog to Digital Conversion), Microcontroller, LCD (Liquid Crystal Display) for displaying the messages. By using this project, one can control the TEMPERATURE and LIGHT by means of a GSM modem by sending SMS. In this application two conditions will be displayed whether we want to change the temperature, light intensity else not that can be varied depending upon the user's requirement. LED Indication is provided on the Kit to know which sensor has been activated.
This project uses regulated 5V, 750mA power supply. 7805, a three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/12v step down transformer. The RFID module requires a separate +5V power.
