In this project, we are using a water level alarm using simple and low cost hardware using a 555 timer circuit. The aim of this project is to operation of the IC 555 in astable mode depends on the values of R1, R2 and C1. circuit is normally disabled and it gets enabled only when the probes touch the water. The distance

31 Jan 2017 5 INTRODUCTION This simple touch sensitive alarm is developed by using NE-555 timer IC, operated as a monostable vibrator. This touch alarm circuit will sound when somebody touches the trigger plate. This is a little and flexible circuit consists of a touch sensor and a NE-555 IC with a small buzzer as the output load.
21 Nov 2016 A touch sensor is a type of equipment that captures and records physical touch or embrace on a device and/or object. It enables a device or object to detech touch,
This circuit utilising a 555 timer IC can be used as an alarm system to prevent the theft of your luggage Power supply failure alarm -designed by Naveen P N Click here for Circuit Diagram. Most of the power supply . Here is a circuit for using the printer port of a PC, for control application using software and some interface
In this project we will make a Touch on Touch off switch circuit using 555 timer IC on a breadboard. This circuit has two Touching one of the conductor pairs turns on the LED and touching the other pair turns the LED off. Watch the You can also use this circuit as a touch alarm by replacing the LED+resistor with a buzzer.

The idea of using sensing devices for convenience, safety, security and quality of service purpose is not new, . R3 and C2 determines the time out period of the 555 timer (i.e. the period at which the alarm.
Simple Touch Switch Circuit using 555 Timer IC. This simple Touch Switch is developed by using 555 timer IC operated as a MONOSTABLE vibrator. Here the stable stage is LOW, so the timer outputs low after the trigger is removed. Basically in this circuit we will have a LED which turns ON when we touch a pin of timer.
