Wireless Sensor Data Logging System Design

Wireless Sensor Data Logging System Design is a standalone electronic
sensor device that captures and stores data through wireless communication. This
system comprises two main integrated components; the Radio Frequency module
and the Microcontroller based system. The main goal of this project is to design
and construct a data logging system that effectively monitors the device's
measurement values. In real life applications, most data monitoring system is a
passive system. This type of system requires manned guarding on site to manage
the devices. Therefore, a standalone data logging system offers a better
enhancement system to replace the manned guarding method. The standalone data
logger system can be applied by leaving the device alone in any place that
requires the measurement of humidity and temperature. These data can be
retrieved from EEPROM and transferred to a PC whenever needed by a user. A
radio frequency module enables these data travels through wireless transmission
medium, whereas the serial communication interface enables communication
between the devices and PC. For diverse applications, an alarm system can be
implemented if assets and security are the major concerns. The final report
presents the development of a data logger system which is an integration of radio
frequency module and the microcontroller-based system. The system monitors the
device's measurement value via a Graphical User Interface. Basically, the system
introduces a RF module to replace the hard wired scheme and produce a dynamic
data transmission system. It is geared up with a PICI6F877A microcontroller to
drive the outputs besides providing communication between devices and a PC.
Overall, the project is the best platform to improve the traditional monitoring
system and ignites another innovative invention in the future.
