Abstract: Hardware monitoring of shearer attitude is realized based on the low-power MSP430149 single chip.Single/dual-axis accelerometer ADXL103/203 is used for the monitoring, TMP05 temperature sensor is used for the temperature compensation to the initial measuring result of the accelerometer and the corrected result which is the final output of the monitoring circuit is transmitted and displayed via single chip 485 bus to facilitate the interaction of human-machine interface.As a result, the temperature drift effect due to underground adverse working environment is reduced, improving the accuracy and reliability of the measuring result.

Key words: Accelerometer, Temperature sensor, Temperature compensation
