Traditional methods of environmental monitoring have the shortages including difficult network layout and low intelligent of node. A monitoring system for temperature and humidity was designed based on ZigBee (wireless network), with SHT11 (temperature and humidity integrated sensor) and CC2430 (wireless radio frequency module integrated with MCU). Data of temperature and humidity, collected at some acquisition terminals in SHT11 and CC2430, were displayed on monitoring host via centre node. By using solution of single chip ZigBee, the system was optimized with high precision, low power dissipation and simple equipment.
