This home made wireless remote controlled switch system is a very easy to construct and can change our living experiance. The circuit has also a good range of upto 20 meters.
Three Push On Push Off Latching Circuits 3 Steps
Wireless on off switch circuit diagram. In this project we are going to show you how to make a wireless circuit using ldr lm741op amp ic and 4017 decade counter ic. The wireless rf remote control onoff switch is used as a switch of your fan lights or other electronic apparatuses even if you are in another room. The infrared rays transmitted by d2 is detected by the. The whole project contains two parts which is an fm transmitter and a rf receiver. Normally home appliances are controlled by means of switches sensors etc. The coil l1 in the receiver circuit is a hand made air cored coil having 6 turns of 24 enameled wire coiled intently on a 5mm structure.
Schematic of the electronic wireless light switch circuit. This is a good solution for a unique and so interesting idea to wireless switching system to control the home appliance. During the interruption the appliance remains on through the relay. Using this simple wireless switch circuit you can avoid the dangers of having physical contact with the switches. However physical contact with switches may be dangerous if there is any shorting. In order to switch on the appliance you simply interrupt the infrared rays falling on the phototransistor through your hand.
A relay switch is used at the output of the circuit which can be connected with the appliances to make them switch onoff. The circuit described here requires no physical contact for operating the appliance. The method implemented here involves a wireless switch circuit where when you slide our hand in front of the circuit the device like lamp will be turned on and if you slide you hand once again the device will be turned off. When you remove your hand from the infrared beam the appliance turns off through the relay. So today we are building a simple wireless switch circuit in which there is no need of physical contact with the switch just one has to take his hand over the switch and it turns onoff the light. You just need to move your hand between the infrared led d2 and the phototransistor q1.
Ir infrared remote controlled switch circuit diagram for lightfan appliance. For good results use a good quality fm transmitter with the circuit.
