CONSTRUCTION AND DESIGN OF DISTANCE PROXIMITY SENSOR USING LDR AND LED
ABSTRACT This project work describes the construction and designing of distance proximity sensor using LDR and LEDs. The construction focuses more on LDR most common types of sensor and widely available. This design was done by using LDR as the sensor and LEDs as the signal indicator at various level of distance with transformer of 230 volt and series of other electrical component highlighted in the work to achieve our ...
