CHAPTER ONE 1.1 INTRODUCTION The light sensitive alarm is an electronic circuit that detects a sudden shadow falling on the light sensor and sounds the bleeper. When this happens, the circuit will respond to gradual charges in brightness to avoid false alarm. The beeper sounds for only a short time to prevent the battery from running flat. Normal light can be use. The circuit will work best if a beam of light is made to fall on the light sensor. Breaking this beam will then cause the bleeper to sound. The light sensor is a light dependent resistor (LDR); this has a low resistance i…
