In this paper, a collector of soil erosion data which uses the wireless MCU MC13213 produced by the company of Freescale as the core controller is designed based on wireless ZigBee technology, integrated temperature and humidity sensor SHT10, the atmos- pheric pressure sensor BMP085, hot film wind speed transmitter WIM120 and whirlwind sand collector. It can realize wireless and real - time acquisition and transmission of the wind speed values, the temperature and humidity values, atmospheric pressure values and the soil wind erosion values. The collector has simple hardware structure, small volume, low power consumption, convenient and flexible for use, simple maintenance and networking. It reduces the difficulties brought by the environmental factors on the measurement and the influence on the result, because there is no need to consider the wiring problems. Experiments show that it can meet 32 communication nodes for data transmission and processing at the same time. Its effective transmission distance is about 200m. The device can be stably used to collect the field wind erosion environmental data.
