AREA OF INTEREST: Industrial Instrumentation Digital Logic Theory ACHIEVEMENTS: Under gone INPLANT TRAINING in ICF (Integral Coach Factory) during January 2007. PROJECTS: MINI-PROJECT Title: New twilite switch. PRINCIPLE: The objective of this project is to switch ON/OFF a light depending upon the sunlight. New Twilite switch circuit is a simple circuit. The hardware of this circuit consists of 4 main parts, 555 IC – Timer, LDR, LED, and NAND Gate. When the light is been in OFF position LDR starts its function & detects that there is no light. This LDR activates the 4093 NAND Gate, which acts as a trigger to the circuit. The trigger IC makes the 555 Timer to activate. The timer makes the LED to make ON. In the 555 Timer the time is set manually by using variable resistance. The circuit do not get affected when the set time gets over the circuit will not go to OFF position or when the light is passed through the circuit. The main advantage of this circuit is when LDR triggers it will not affect the light variation moreover it will not affect the 555 timer after triggering. The NAND Gate is used as the activating element for LDR. This New twilite switch is mainly used in night time room lights which automatically triggers ON in night & switches OFF in day. MAIN PROJECT Title: Remote monitoring of Temperature using microcontrollers & chordless phone. PRINCIPLE: The aim of this project is to develop wireless communication for transmitting data’s between two microcontrollers. The hardware of this system consists of two 89C52 microcontrollers as CPU, MODEM, RF Transmitter & Receiver (using chordless phone), Control keys, & LCD display. In addition the system in receiver end will have the Temperature sensor, signal conditioning circuit & TRIAC switch to control the supply to heater. The system consists of two sections 1. Transmitter section & 2. Receiver section, At the Transmitter section the 89C52 microcontroller is connected parallel to the Modem (signal conversion) & RF Transmitter & Receiver. On the other side of the microcontroller, LCD display & control keys (set value of temperature) are connected. At the Receiver section the 89C52 microcontroller is connected to the Temperature sensor, Signal conditioning circuit & TRIAC switch. This Microcontroller displays the temperature on the LCD, as well as the temperature is Transmitted to the Microcontroller at the other end for display in the LCD of the microcontroller in the Transmitter section. The set value of temperature entered through control keys by the user is transmitted through serial port of microcontroller to the MODEM. The MODEM modulates the serial data by FSK principle & then sends to RF modulator for frequency modulation & transmission through antenna. The Transmitted data is received by the antenna at the receiving section & passed to FM demodulator for demodulation. After demodulation the signal is sent to MODEM for conversion to digital data by FSK demodulation & then transmitted to serial port of microcontroller at the receiving end. The microcontroller at the receiving end also reads the actual temperature through temperature sensor & compares with set value, to generate a control signal for switching ON/OFF of the TRIAC switch to control the temperature.
