Temperature Software Compensation of Air Level Posture Sensor
Based on operation computation of signal chip MSC1214, Output signal processing of air level posture sensor is carried on, including temperature –zero voltage compensation, temperature-sensitive voltage. The results show that the change quantity of sensitivity drops to ≤1%; the operating temperature scope expands from the normal temperature to 30°C; in this temperature range, the change quantity of zero voltage drops from ≤0.23V to ≤0.01V, depressing the influence caused by temperature and improving the measurement accuracy of air level posture sensor.
