Design of Multipoint Temperature Gathering System Based on ZigBee Technology

In order to solve the problems of traditional multipoint temperature acquisition system such as the cable distribution is complex, high cost, system design, maintenance and upgrade difficulty. Based on ZigBee technology, using CC2430 as the core chip temperature detection system, in order to meet the low cost, low power consumption, design a multipoint wireless temperature acquisition system. The sensor node is composed of digital temperature sensor DS18B20 and CC2430, the collected temperature signal wireless transmission with CC2430 as the control core coordinator, the coordinator receives temperature data can be displayed in real-time, and sent to the PC machine. The experiments show that temperature sensor contacts can receive 60 m outside the emission of indoor coordinator, temperature measurement precision of 0.7 ℃, meets the expected design requirements.
