摘要
From the view of practical application, this paper designs an infrared information collection nodes, the coordinator node, wireless transmission system using CC2430 microcontroller, and in detail design the infrared sensor （temperature, heart rate, ECG / pulse） circuit diagram. This paper set up a wireless network （ZigBee protocol）, sensor signal acquisition, wireless transmitting and receiving, serial communication software design of coordinator node and PC machine. Finally, we on-line debug each module of the system hardware and software. Experiments show that the network node data transmission accurate, reliable work, has basically met the design requirements.
