摘要：This paper presents design and development of intelligent sensor node for environmental monitoring. The node is equipped with multimode sensors for sensing different environmental parameters, the node can sense four different environmental parameters, light, temperature, humidity, and three different types of gases. The node has half duplex wireless communication feature which is achieved by using an IEEE 802.15.4 standard compliant transceiver. Here we have deployed various intelligent protocols to achieve intelligent power management and precision sensing. The node comes with various error detection and correction capability which enhanced the performance of the node. Two different types of methodology are used to prove the intelligence of the node. The node is equipped with multiple sensors like gas, temperature, and humidity, light. A Special remote system enables user to wirelessly select the particular sensor which provides high wireless hardware flexibility. More priority is given to power consumption and sensing efficiency which is achieved by incorporating various smart tasking and power management protocol. All sensed data are digitized and processed by the internal analog to digital converter (ADC) of a Programmable interface controller (PIC) microcontroller and wirelessly transmitted to the base station for data acquisition and statistical analysis.
