Abstract :
The high number of theft cases in mosques is still a problem in the community,
which is still a lack of attention in mosques, for security in mosques the security
system must also be maximized because in mosques there is only CCTV (Closed
Circuit Television), it only displays visuals but theft often occurs in mosques.
In this research, the design of a security system based on Arduino UNO as a
central control system with a Reedswitch sensor, and also a connection to the
Bluetooth Transmitter and Bluetooth Receiver, will be designed when the Bluetooth
Transmitter box contains the Reedswitch sensor, the buzzer on the Bluetooth
Receiver will sound.
From the incentive design of the sensor and the Bluetooth connection on the
device, it can still be connected at a minimum distance of 0.5 meters and a maximum
distance of 20 meters for Reedswitch and if it is more than that, the sensor cannot
be read by the Transmitter for Bluetooth connections, a maximum distance of 21
meters for pairing system, the connection takes time. And if the sensor is opened the
buzzer will sound.
