wireless switch circuit using cd4027 detail information in pdf - manmaya - 10-04-2017
The circuit is made up of Operational amplifier LM741 which is employed like a comparator for sensitive voltage, LDR , Preset VR1 is used to give a reference voltage to the pin 3 which is a non-inverting terminal as well as to LDR and R2 is linked with IC1 at inverting pin 2 along with a few additional components.
It is very simple to understand the working of the circuit. LDR device will not start till we do not pass our hand over it and as a result of it IC1 pin 2 move to high state. And as a result of its low state is achieved by the IC1 pin 6 which is an output pin.
Now as soon as someone passes their hand over LDR, IC1 pin 3 is set to high as compared with the IC1 pin 2 as a result of its pin 6 reaches to high state which supply a clock pulse to 13 pins of IC2 (a flip flop IC). The logic level present at the input terminal ie. J and K guarded the state of a flip flop with the help of some internal control. With the positive going cycle of the clock changes occur. Set and Reset pin are not dependant on the clock and it started when high signal is provided to any one of the input pins.
The circuit revealed is triggered on the primary rim of the switch pulse ie output vary when you once more place your hand above LDR. As in the circuit you can find that J and K both attached to high input which implies that at each transition of the clock pulse whether negative or positive pin 13 fluctuate between high and low. This can be demonstrated with the assist of JK flip flop truth table. Hence when it got the pulse from clock from IC1 as of hand above LDR transistor attached to pin 15 begins condition and the output is get with the help of relay attached in the circuit. With the help of the VR1 sensitivity of LDR can be adjusted.
