摘　　要：CC2530作为传感器数据处理电路主要微控制器,建立温度传感器和水平姿态传感器的Zigbee网络,对姿态传感器的温度补偿及线性度补偿可以在线进行。结果显示因为温度变化引起的灵敏度变化下降到≤0.9%;工作温度范围从常温扩展到35°C;在这个工作温度范围内,零点电压的大小从≤0.25V下降到了≤0.008V,减少因为温度变化带来的灵敏度的变化,水平姿态传感器的测量准确度进一步提高。In this article CC2530 is the core of the compensation circuit,building the Zigbee internet of temperature sensor and posture sensor,getting real compensation.The range of compensation includes zero-voltage compensation and temperatue-sensitivity compensation.The experiment results show that:the sensitivity flowing because of environment temperature is smaller than≤0.9%;the working temperature range expands from normal temperature to 35°C;in this range zero-voltage decreases from≤0.24Vto≤0.007V,lowering the sensitivity change based on the change of environment temperature,increasing the measurement of air posture sensor.
