Touch the sensor of the alarm with your finger and it starts beeping, goes on for some time and then stops. Touching it again, and it goes again! This little and flexible circuit consists of a touch sensor and a directly coupled transistor amplifier with a small loudspeaker as the output load. Two sensor strips of metal are mounted side by side on a 1 1 cm size micasheet and connected to the input of the circuit.

How the touch alarm works

Under normal conditions no current flows through switching transistors T1 and T2 and the potential acros ....etc

sir,
this is venkateswarlu mannepally working as asst professor in eletronis and communications branch.i want work on the project it is related to cc camera based bomb detection with siron.by using cc camera+spectro meter+laser light+siron ,is there any possibility to find ccbased bomb detector with siron to decrease human loss at bomb blasts.please send any information regarding this topic.
thanking you sir.

ABSTRACT
This research focuses on detection of unauthorized access to residential and commercial buildings when
the residents are far away from the access gate of the house. The system is a simple and reliable touch
activated security system and uses sensor technology to revolutionize the standards of living. The system
provides a best solution to most of the problems faced by house owners in their daily life. Due to its
simple electronic components nature, it is more adaptable and cost-effective. The system is divided into
three units; t ....etc

TOUCH SENSITIVE ALARM


How it works
Heart of the circuit is a single 40106 hex Schmitt trigger
inverter IC, together with a piezoelectric alarm unit and a
handful of other components. The first Schmitt Inverter
(IC1a) together with its associated 10kW-feedback resistor
and 22pF capacitor forms a simple oscillator with a nominal
frequency around, 1MHz. The oscillator output passes via
a 15pF capacitor to a second Schmitt inverter, IC 1 b,
which in turn is AC-coupled to a full ....etc
