The main objective of this project was to ensure a proper security to building against theft or intruder. The circuit uses 555 timers IC which was wired as a timing circuit, amplifier to obtain a maximum audible sound. The 555 timer times the circuits and also generates a tone and this tone is send to transistor which amplifies the tone generated through a loud speaker or buzzer. This device functions as a major security alarms used i […]
Most of the Remote control systems use TSOP 1738 IR Sensor module to control various functions. This IR Sensor is highly sensitive and may damage easily, if is supply voltage increases above 6 volts. This tester is useful to check the working of the IR Sensor. It gives audio-visual indications when the IR sensor is working properly. TSOP 1738 is designed to sense 38 kHz pulsed infrared rays used in remote handsets. The IR Sensor has […]
ABSTRACT This project work is titled design and construction a solar Street Light Control system with proximity sensor. A street lighting is any electrical lighting that is fixed in the road for the illumination of such road or a Street light is a raised source of light on the edge of a road or walkway, which is turned on or lit at a certain time every night using solar energy (solar panel) as the primary power supply. An Automatic S […]
ABSTRACT An automatic electric light switching system with proximity sensor system detects moving objects, particularly people. An automatic security light control and motion detection system is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area. An automatic electric light switching system with proximity sensor form a vital component of automated lighting control. Its […]
ABSTRACT Proximity sensor detects the presence of nearby objects without any physical contact using infrared sensor. The infrared sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity sensor's target. The operating distance of the sensor depends on the actuator's sha […]
ABSTRACT Proximity sensor detects the presence of nearby objects without any physical contact. Examples of proximity sensor usage include detecting an out-of-paper condition in a printer or a mobile phone screen that dims to save battery life when placed near a face. Proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signa […]
