嗨,我正在使用HTS221和STM8L052C6。通信通道是I2C。
我能够获得高达99%RH的湿度数据。但是在读取数据的某些点之后,传感器会被挂起并且即使在电路复位后也无法恢复。我还发现在这种情况下SDA线仍然很低。 任何帮助将不胜感激! 谢谢, unnati 以上来自于谷歌翻译 以下为原文 Hi, I'm using the HTS221 with STM8L052C6. The communication channel is I2C. I am able to get the humidity data upto 99% RH. but above this after some point of reading the data,the sensor gets hanged and is not recoverable even after circuit is reset. i also found SDA line remains low in this condition. Any help would be greatly appreciated! thanks, unnati |

嗨,
我需要更多信息。 你在用什么设置?一枪? ODR?等等。 您是否在不受控制的环境或RH饱和至100%的受控环境中进行测量? 设备出现故障多久后? 你只检查一台设备或更多? 问候 安东内拉 以上来自于谷歌翻译 以下为原文 Hi, I need additional information. What setting are you using ?One shot?? ODR?? and so on. Are you getting measurements on not controlled environment or on controlled enviroment with RH saturated to 100%? After how long the device fails? Do you have check only one device or more?? Regards Antonella |

我正在测量受控环境,RH饱和度达到100%。 我已检查过2台设备,两者都出现同样的问题。 该设备失效约15分钟。达到99%RH后。 我每隔10秒从传感器读取数据,每次使用以下设置初始化和取消初始化传感器: 为了初始化HTS221,我写CTRL_REG1 = 0x80; CTRL_REG2 = 0x01; 对于DEINITIALIZING HTS221,我写CTRL_REG1 = 0x00; 传感器的供电始终打开。 问候 unnati 以上来自于谷歌翻译 以下为原文 hi, i am getting measurements on controlled enviroment with RH saturated to 100%. i have checked with 2 devices and the same problem occurs for both. the device fails approx 15 mins. after reaching 99% RH. i read the data from sensor every 10 sec and everytime i initialize and deinitialize the sensor with following settings: for initializing HTS221 ,i write CTRL_REG1 = 0x80; CTRL_REG2 = 0x01; for DEINITIALIZING HTS221, i write CTRL_REG1 = 0x00; the supply to the sensor is always on. regards unnati |

嗨,
使用的设置似乎很好。 你应该考虑到在这种情况下它很可能会产生冷凝。 我猜这个故障与使用过的接口(电路板,接线等)的故障,短路等有关,而不是与设备本身有关。 我建议你注意这个方面。 问候 安东内拉 以上来自于谷歌翻译 以下为原文 Hi, the used settings seem good. You should keep in consideration that in this situation it is very likely to create condensation. I guess the failure is related to malfunctions, short circuits and so on of the used interface (board, wiring, etc.) and not to the device itself. I reccomend you to pay attention to this aspect. Regards Antonella |

嗨,
这个问题可能与时间有关,而与湿度百分比无关。 由于使用了ONE-SHOT模式并且传感器正在通过PD位关闭,请参阅主题 https://community.st.com/0D50X00009XkVvtSAF 祝你好运! 注意:原始帖子包含大量线程对话,只能迁移到第9级 以上来自于谷歌翻译 以下为原文 Hi, This problem may be related to time and not percent humidity. Since ONE-SHOT mode is used and the sensors is being powered down with the PD bit, see topic https://community.st.com/0D50X00009XkVvtSAF Good luck! Note: the original post contained a large number of threaded conversations and was only able to be migrated to the 9th level |
