LASER based security system using wireless sensor network and GPRS/GSM technology for inland aquaculture in Bangladesh

摘要

Our paper deals with the design and implementation of a novel LASER based security system for inland aquaculture such as Shrimp/prawn farming perspective to Bangladesh. The system implements LASER as a mean of detecting intruders. A wireless sensor network based on nRF24L01 trans-receiver is used to communicate with the gateway and the sensors. The number of LASERs obstructed is determined by LDRs attached to an Arduino board; which is programmed to take decisions whether to sound an alarm or call a desired mobile number through a GPRS/GSM network; depending on the number of LASERs obstructed. The proposed work has been done and verified in real life. The system was satisfactory in terms of both cost and security compared to other existing systems available in Bangladesh.
