ZigBee holds wireless sensor network technique,communication technique ,computer technique hanging together.,can be provided with information collection,transmission,manage. It is intervenient wireless badge and Bluetooth. ZigBee has a burgeon stone's throw, low complexity, low wear energy, low transmission velocity, low price wireless communication technique, which between wireless marker technique and Bluetooth’s technique resolution. The task transit adopt Atmega singlechip and receive module CC2420 design wireless network hardware node,draw correspond principle chart and design software flow chart and temperature humidity program. The sensor network will be improved in the future aiming at the enhancement in data processing and communication areas.
