ally as the day starts. The duration of the day differs from season to season, accordingly our module works based upon the light intensity so as to when to start or stop. For this we are using Light Dependent Resistor (LDR) as the light sensor, which communicates with the required information to the micro controller.
Here we are using micro controller, LDR, and relay. By using the LDR we can operate the lights, i.e when the light is available then it will be in the OFF state and when it is dark then the light will be in ON state, it means LDR is inversely proportional ..................[:=> Show Contents <=:]

The temperature sensor LM35 senses the temperature and converts it into an electrical (analog) signal, which is applied to the micro controller through ADC. The analog signal is converted into digital format by the analog-to-digital converter (ADC). The sensed and set values of the temperature are displayed on the 16x2-line LCD. The micro controller drives contro..................[:=> Show Contents <=:]

e part of the experimentalist. The wide range of pressures to be measured under the general heading of vacuum measurement makes the problem an extremely extensive one. This range extends from the normal atmospheric pressure of 760 mm of mercury column down to 10 to power-8 of mercury column. For this measurement of vacuum, also we have a number of sensors that can be given below.
A) Pirani gauge
B) Knudsen gauge
C) McLeod gauge
D) Thermocouple gauges
Over here we are using the pirani gauge type of vacuum measurement. The operation of pirani gauge depends on variation of thermal conductivi..................[:=> Show Contents <=:]

REGULATORY CIRCUIT
The regulatory circuit is powered by the control circuit output.The normally open contact of the control circuit relay is connected to provide supply as shown in circuit diagram.The regulatory circuit makes the fan run at full speed for a pre-determined time. The speed decreases to medium after sometime, and to slow later on. After a period of about eight hours, the fan/cooler is switched off. IC3 (555) is used as an astable multivibrator to generate clock pulse. The pulse is fed to decade divider/counters formed by IC4 and IC5. These ICs act as d..................[:=> Show Contents <=:]
