Wireless temperature sensor network based on DS18B20, CC2420, MCU AT89S52

摘要

Wireless sensor network (WSN) has extensive applications including temperature testing. Thus, this paper utilizes three fundamental chips, i.e., DS18B20, CC2420, MCU AT89S52, to design the wireless temperature sensor network (WTSN) via the ZigBee technology. The novel network sequentially transmits the temperature information to the substation, node, computer, thus realizing the wireless temperature monitoring. The WTSN holds prominent advantages regarding the high detection precision, the low power consumption, the high cost performance, and the high reliability. Thus, it could widely apply to the Internet of things field to effectively perform the temperature testing.
