你好,
我还想知道,为什么LPS25HB测量的环境温度(15-25厘米)比其他温度传感器低4厘升(例如)
HTS221和
校准Sensirion的SHT21 a SHT31)。中提到的公式
http://www.st.com/content/ccc/resource/technical/document/technical_note/23/dd/08/f8/ac/cf/47/83/DM00242307.pdf/files/DM00242307.pdf/jcr:内容/翻译/ en.DM00242307.pdf
使用42.5厘米的偏移量。它是固定值,还是可以在设备中设置的值?我使用

我希望可以排除不良的PCB设计和/或焊接。感谢您的任何建议。

Hello,
I would also like to know, why does LPS25HB measure ca 4 centigrades lower ambient temperature (15-25 centigrades) than other temperature sensors (for example
HTS221 and
calibrated Sensirion's SHT21 a SHT31).The formula mentioned in
http://www.st.com/content/ccc/resource/technical/document/technical_note/23/dd/08/f8/ac/cf/47/83/DM00242307.pdf/files/DM00242307.pdf/jcr:content/translations/en.DM00242307.pdf
uses an offset of 42.5 centigrades. Is it a fixed value, or value that can be set in the device?I use

board, so I hope bad PCB design and/or soldering can be ruled out.Thank you for any advice.
