Automatic lighting control for fluorescent lamp
MetadataShow full item record
This paper is to develop an automatic light control of the fluorescent brightness depending on the site environment. The brightness can be controlled by using the pulse width modulation (PWM) technique. The input signal of PWM obtained from the brightness values of the light dependent resister (LDR). Based upon the standard of an illuminance, there are nine rooms assigned under the particular illumination. This leads to save electricity in our house which becomes increasingly important in recent years. Results show that the system can work as intended.
