Low Rate Wireless Sensor Network Data Logger with Multi-core Microcontroller

Abstract

This paper presents the development of a data logger which collects interesting data via low rate wireless sensor network, not expensive, low power consumed sensor node. The system is wireless and more flexible to expand and substitute sensor nodes by add proper configuration wireless sensor node. System controller uses embedded small multi-code microcontroller, Propeller Chip by Parrallax Inc. This chip contains eight processors (Cogs) inside. All eight processors can perform tasks simultaneously or with coordination from other processors. It comprised of Xbee chip to perform wireless sensor network that work with 802.15.4 protocol. Data is collected and stored in Micro SD memory, small size and not expensive. It transfer data from data logger to master computer system via wireless network. The experimental results show that we can use single microcontroller based on data logger system, small size and flexible. To expand this system with Propeller chip, it can monitor data collected by system directly from this chip by generating computer screen monitor signal.
