Design of a portable system for sensor data acquisition and transmission

Abstract

The current paper represents a portable battery powered system which is capable to measure and analyze the data from different type of sensor data like humidity, air pollution gases, dust, smoke, etc. and send it via Bluetooth or GSM/GPRS connection to the remote devices. It contains GPRS modem with integrated Bluetooth module, integrated chip antenna, power management module, rechargeable Li-Ion battery and some analog or digital I/Os to connect to the internal or external sensors for data acquisition. This system may be used as a remote sensor system in smart homes, air monitoring stations, etc.
