| dc.description.abstract | The building is a critical civil infrastructure
for human life, so it needs maintenance. One way of
maintenance is to monitor the condition of the building
regularly so that it can minimize early damage and use
can last as planned at the beginning of manufacture. The
monitoring process can be done manually, but it is less
efficient considering the increasingly advanced
technological developments. Wireless sensor network
technology can be used to monitor this because it does not
require a wire loop, and data transmission is carried out
wirelessly where sensors have been placed in several
locations. Therefore, a prototype was tested using a
vibration sensor (SW-420) which detects vibrations. The
protocol used is the ZigBee protocol (802.15.4) with a
mesh topology. The results of the tests that have been
carried out are that distance dramatically affects. The
RSSI parameter is influenced by the distance, namely, the
farther the distance between the transmitter and receiver,
the smaller the RSSI value, which means the signal is of
poor quality, and vice versa. This result is evidenced at a
distance of 4 m RSSI average of -75.7 dBm and a distance
of 16 m RSSI average of -81.7 dBm. | en_US |
