Design of a Room Monitoring System for Wireless Sensor Networks

Abstract EN

In wireless sensor networks (WSN) systems, various indoor environmental parameters can be monitored in real time by an RF wireless sensor module.

A wireless sensor module with several sensors is developed for an indoor environment monitoring system.

ZigBee is a wireless standard for personal area network (PAN) sensor monitoring and control, also known as IEEE 802.15.4.

In this paper, we designed a wireless sensor module that had a ZigBee communication module and a sensor module for monitoring a room or an office environment using WSN.

The sensor module has various enlargements for various types of sensors, for example, a humidity sensor, temperature sensor, and O2 and CO2 sensors.

Using ZigBee technology of 2.4 GHz Industrial, Scientific, and Medical (ISM) band, we could monitor the information from terminal PC modules that are attached to the wall of an office or a room.

A wireless sensor device was developed to circuit schematic using PowerPCB tool PADS and made it a printed circuit board (PCB).

From the results of our tests, we confirmed that the designed wireless sensor module and room monitoring system can supply a comfortable environment for people by monitoring the indoor environment.
