我有
对温度对加速度计和陀螺仪读数的影响研究很少。 将传感器在摄氏温度下冷却至负温度，然后在IR灯下加热至约50度，完全静止而不移动。 而且我注意到了一些奇怪的事情。关于加速度和角速度对LSM6SL温度的依赖关系图呈现出非线性跳跃。我想从ST开发人员那里得到解释这个效果。 PS LSM9DS1在更小程度上具有这种效果。 LS303AGR没有这种效果。 ＃lsm303agr＃lsm9ds1＃lsm6dsl＃accelerometer-gyroscope-temperature-dependence 以上来自于谷歌翻译 以下为原文 I have conducted little research of temperature influence on accelerometr and gyroscope readings. The sensors were cooled to a negative temperature on celsius, and then heated under the IR lamp to approximately 50 degrees in complete rest without movement. And I have noticed some strange thing. On the graph of the dependence of acceleration and angular velocity on temperature for LSM6SL present nonlinear jump. I want to get explanation of this effect from ST developers. PS LSM9DS1 has such effect in in a more less degree. LS303AGR hasn't such effect. #lsm303agr #lsm9ds1 #lsm6dsl #accelerometer-gyroscope-temperature-dependence

您能否提供更多细节，您是如何进行测试的（设备，时间......）？特别是你是如何冷却设备的？
这种行为可能是由测试期间的水积累引起的。 以上来自于谷歌翻译 以下为原文 Can you please provide more details, how did you perform the test (equipment, timing, ...)? Especially how did you cool down the device? The behavior could be caused by water accumulation during the test. |

将该板在冷冻室中冷却至约-5摄氏度，然后通过具有磁性紧固件的机架安装在重金属基板上，所述磁性紧固件在具有反射器的IR灯下。此外，威廉希尔官方网站

加热持续约15分钟（见图表）在发生液滴的相同温度下，在温度的增长中观察到制动 实际上发生了水滴凝结，但这又如何影响加速度计和陀螺仪读数的差异？ 以上来自于谷歌翻译 以下为原文 The board was cooled down in freezer compartment to approximatly -5 degrees Celsius, after that it was mounted at heavy metal substrate on by means of racks with magnetic fasteners under IR lamp with reflector. Also, the board was fenced on all sides by walls to prevent the movement of air masses. Heating lasted about 15 minutes (see graph) At the same temperature at which the drop occurred, braking is observed in the growth of temperature Condensation of water droplets actually occurred, but how does this affect the difference in the readings of the accelerometer and the gyroscope? |

在这种情况下，确认问题是由水（湿度）引起的。由于T增加导致的封装湿度吸收和随后的湿度降低引起机械应力，其改变封装力平衡，从而引起影响MEMS的应力。
这种变化被转换为数字输出的变化。 以上来自于谷歌翻译 以下为原文 In this case it is confirmed that the problem is induced by the water (humidity). The package humidity absorption and the consequent humidity reduction due to T increase induces a mechanical stress that modify the package forces equilibrium, thus inducing stresses that affect the MEMS. This change is transduced as a change of digital output. |
