Embedded Sensing Module for Real Time Remote Monitoring Applications

Monitoring the various parameters is very crucial in the field of real time remote sensing area. Considering the wide potential applications of this field the present paper details the smart sensing array for the remote monitoring applications. This is implemented with a number of high-performance front-end circuits for various types of sensors. Sensors elements can be directly connected without the need of extra circuits. The present available sensor interface allows a limited 4 to 5 sensors at input. The present paper describes development and typical features of a low-cost, highperformance interface. All parameters and set point values are displayed on LCD and are stored in external EEPROM for future reference. The developed system can be connected to a host Personal Computer using wired RS-232 interface and wireless (IEEE 802.51.4) connectivity using the Xbee-PRO-PKG RF modem.
