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 goal. This device was tested in an outdoor environment to evaluate the proximity detection and warning technology. Experimental results show that proximity sensing and warning technologies can provide alerts to equipment operators at different proximity alert ranges. The results suggest that safety can be promoted in a laboratory and field experiment by implementing real-time proximity sensing and warning technology. The theory, design, circuit analysis, and circuit diagram were provided to give adequate information about the design.
