Smart Power Meter System Based on ZigBee
Abstract:
The Smart power meter system based on ZigBee technology is successfully developed in the paper. The EM250 SOC chips are adopted to develop the wireless communication modules with ZigBee protocol. Parsing the AT command, encryption and such more basic function, the two different and independent program framework for the ESP and IHD(In-Home Display) have been worked out except finishing the data transmission. A smart wireless network based on ZigBee has been established. The home and outdoor testing have also been implemented too. The measured results show that a coordinator can support more than 500 nodes and communication distance reach more than 1000 meter outdoor and more than 50 meter from home to outdoor through the two walls.
