Specification

Description

This Touch Sensor using a 555 timer is a very simple touch sensor switch that is built with the 555 timer IC. You just need to touch the metal plate and the led gets energized and is kept in this state for about 100 seconds, then is turned off. This kind of sensor switch is suitable for making touch-operated bells, buzzers of small toys which operate for a small time and then switch off automatically.

The input impedance of the trigger is very high and the touch sensor switch can be triggered by the voltage induced in the human body. The monostable mode of operation of 555 IC can be explained using a simple touch-sensitive circuit. Here, the timing constant (T) of the monostable timer= 1.1*R2*C2. The Touch Sensor Circuit has been configured in monostable mode. A monostable circuit produces a single pulse(for a certain duration determined by the Timing Constant(T)=1.1*R2*C2) when triggered at pin 2.
