SENSOR NODE ARCHITECTURE Sensor Node consist of following five main hardware component Controller Memory Sensors and actuators Communication device Power supply

Schematic diagram SENSOR NODE ARCHITECTURE MEMORY COMMUNICATION DEVICE CONTROLLER SENSOR /ACTUATORS POWER SUPPLY

DEVICES AND EXAMPLES OF FIVE COMPONENT OF SENSOR NODE 1-Controller-Microcontrollers, microprocessors, FPGAs, and ASICs. EXAMPLE-Intel StrongARM,Texas Instruments MSP 430 2-Memory-RAM,ROM ,EPROM 3-Sensors and actuators- Types of Sensor I}Passive, omnidirectional sensors II] Passive, narrow-beam sensors III] Active sensors Actuators -Actuators are just about as diverse as sensors, yet for the purposes of designing a WSN, they are a bit simpler to take account of: In principle, all that a sensor node can do is to open or close a switch or a relay or to set a value in some way. EXAMPLE- 4-Communication device-Transreciver 5-Power supply-Battery,conventional energy storage,Energy scavenging
