Signal processing technique of omnidirectional gasflow style horizontal Posture Sensor

This paper introduced the structure principle and the signal processing technique of the omnidirectional gasflow style horizontal Posture Sensor. The heat sensitive resistance was used as heat source and sensitive unit, and the natural convection of the gas was produced in a hermetic chamber. The posture signal of carrier was got and processed by hardware circuit and software compensation technique, so it can measure the omnidirectional horizontal posture of the carrier when the carrier were in any yawing direction.
