Wireless dual-axis tilt sensor is a measuring instrument used MEMS tilt sensor to collect information,and transmit wirelessly the angle of measured object end on the measurement site. Firstly,the working principles of the tilt sensor measurement are discussed. Dual-axis acceleration sensor is used to measure the acceleration signal and tilt signal simultaneously. Secondly,a hardware system consisting of tilt measurement module,controlling module,vision module,RF module is designed. A single chip microcomputer of STC89C52 is used as control core,ADXL202 acceleration sensor and wireless chip CC1110 are used to design the wireless dual-axis tilt sensor hardware circuit,and MCU is used to receive the front of the data collected the recuperation and display on the LCD. The system is small size,good stability,low power consumption,high communication efficiency. Therefore,it can be widely used in measuring,monitoring,alarm and some other industrial areas.
