Normally, home appliances are controlled by means of switches, sensors, etc. However, physical contact with switches may be dangerous if there is any shorting. The circuit described here requires no physical contact for operating the appliance. You just need to move your hand between the infrared LED (IR LED1) and the phototransistor (T1). The infrared rays transmitted by IR LED1 is detected by the phototransistor to activate the hidden lock, flush system, hand dryer or else. This circuit is very stable and sensitive compared to other AC applia ....etc

A clap switch circuit is a classic beginner s project.
Equipment can be switched on and off by just clapping your hands. Add a tiny microcontroller and you can easily build-in some more useful features.

The microcontroller in this circuit makes it a simple job to add some useful features that are not seen on other clap switch designs:

Changeover relay contacts enable the unit to be wired in conjunction with a manual changeover switch so that manual override of the switched equipment is always possible.
The unit is only responsive to a specif ....etc

Wireless switch circuit using CD4027
SUMMARY OF THE PROJECT
Work in wireless switch circuit using CD4027. Using this scheme, you can control any electrical device, just passing a hand over the LST.
DESCRIPTION OF THE PROJECT
Work in wireless switch circuit using CD4027. Using this scheme, you can control any electrical device, just passing a hand over the LST.
These schemes largely depending on the two chips. The first of these is LM714, which is the operational amplifier. This IC is used to increase the voltage output of the hundred of thousan ....etc

CLAP SWITCH


Here s a clap switch free from false
triggering. To turn on/off any ap
pliance, you just have to clap
twice. The cir-cuit changes its output state
only when you clap twice within the set
time period. Here, you ve to clap within 3
seconds.
The clap sound sensed by condenser
microphone is amplified by transistor T1.
The amplified signal provides negative pulse
to pin 2 of IC1 and IC2, triggering both the
ICs. IC1, commonly used as a timer, is
wired here as a monost ....etc
