Data transmission period consideration on the internet of thing node

Abstract

Internet of Things (IoT) has been very assistive in monitoring remote sites by placing some sensors connecting to the internet. Some sensors are located in fully available electrical sources; while some applications rely on the use of a battery. This paper concerns the latest, considering the quality of the sensed data against the power shortage. Vibration detection is chosen as the measured application. The remote sensor was designed by using MPU 6060, controlled by ATmega328 and connected to the internet through an intermediate node using 433 MHz radio. Intermediate node was controlled by ATmega8. Vibration data sent to the internet consists of minor and major vibrations. Major vibration occurs incidentally. Measurement shows that the sorter the data transmission period, the more effective sensor detecting major vibration. It is shown by the increment of vibration amplitude when the transmission period shorter. However, the more frequent the transmission, the more energy required. The assessment shows that data quality and power lifetime are determined by the transmission period.
