light controlled digital fan regulator pdf

Mans are born of habit, and we all want comfortable. At night while sleeping we often switch of the light. But sometime we used to increase or decrease the speed of fan. And it is very difficult to trace the switch board in a dark room at night and to wake-up from bed is also irrigative. By keeping this problem in mind the group of electronics geek at Dreamlover technology designed and verified a circuit light-controlled digital fan regulator. By using this circuit one can control the fan speed with a torch light remotely from the bed. The speed of fan can be varied by number of times focus on the LDR (light- dependent resistance) of the circuit. LDR is a semiconductor which changes their resistance according to the intensity of light.

Circuit description of light-controlled digital fan regulator

The circuit of light controlled fan register is build around times IC, decode counter (7490), BCD to 7-segment driver(7447), BCD –to decimal decoder, hex inverter, common-anode 7 segment display, LDR and few other components.

Circuit description of light-controlled digital fan regulator

The circuit of light controlled fan register is build around times IC, decode counter (7490), BCD to 7-segment driver(7447), BCD –to decimal decoder, hex inverter, common-anode 7 segment display, LDR and few other components.

Timer IC (IC1) is configuring in monostable mode (timer) and its time period is adjusted to 1.3 seconds. The fan regulator is triggered when torch light fall on LDR1. In every focus of torch light the resistance of LDR1 goes low which trigger IC1. The every monostable clock is counted by decode counter IC2, given to pin 14 or clock pin as shown in circuit diagram. The output of IC2 is given to IC3 and IC4 parallel.

IC3 is a 7 segment display driven where output is given to 7-segment display. Here 7-segment display is used to display the number of times you focus the torch light on LDR1. As shown in table1 in every even number the fan will be off, where with increase in odd number, the speed of fan also increases.

The output of IC4 (BCD to-decimal decoder) is given to hex inverter IC. The output from pin 2,4,6,9 and 11 is given to reply driver circuit through corresponding reply driver circuit. The even number output of IC4 is not used. Due to this the fan turns off in every even-number.
