A scheme of the hardware design of a low cost wireless sensor network node which can detect magnetic signal is introduced.The 16 bits MCU MSP430F149 is used as the core
combined with peripheral sensor AD8307 makes up of wireless sensor networks detectting node.Two kinds of IC for measuring magnetic fields are decribed concisely and a comparison between these methods is made.The node has many characteristics such as small in size
low power dissipation
low cost and so on.Detection of the target magnetism signal is also realized.
