Wireless switch circuit diagram. Go through cd4017 circuits to learn more about this ic. And here is one simple application of toggle switch to understand the working of 4017 to latch the output. The circuit is built around an ic ca3140 irled1 photo transistor and other discrete components. The circuit diagram circuit description and working are described in the following sections. In this project we designed a simple wireless switch that uses simple hardware to achieve the action of switching. Wiring a 3 way light switch is certainly more complicated than that of the more common single pole switch but you can figure it out if you follow our 3 way switch wiring diagram.
Pin diagram pin configuration of ic 4017. Current consumption is low in milliamperes. The working of the circuit is simple. These modules are cheap for its functions and are easily available. This wireless light switch is very stable and sensitive compared to other ac appliance control circuits. Circuit diagram of rf transmitter and receiver.
This gallery contains network diagrams for wireless wired and hybrid home networks. Circuit principle the main principle of this wireless switch circuit is in the functioning of ldr lm741 op amp and a cd4027 jk flip flop ic. Many home network layouts work fine but most are variations on a basic set of common designs. This circuit is very stable and sensitive compared to other ac appliance control circuits. For good results use a good quality fm transmitter with the circuit. Wiring a 3 way light switch.
It is simple compact and cheap. Current consumption is low in milliamperes. Each network diagram includes a description of the pros and cons of that particular layout as well as tips for building it. It is simple compact and cheap. Using this simple wireless switch circuit you can avoid the dangers of having physical contact with the switches. In this wireless switch we have used 4017 ic to latch the output to one pin when we pass the hand over ldr.
A relay switch is used at the output of the circuit which can be connected with the appliances to make them switch onoff. The most common type of wireless communication between the switch and the appliance is rf transmission. When regulated 5v is connected. The complete circuit diagram including the transmitter and receiver part for this project is shown in the images below. The whole project contains two parts which is an fm transmitter and a rf receiver. In this project we will learn how we can build wireless projects using a 433 mhz rf module.
The circuit has also a good range of upto 20 meters.
