Pressure Sensors Forum Discussions
各位好,我在使用dps368进行参数测量,目前温度测量是正常的,但是气压的变化数据实在过大(静止状态下),我想询问下论坛里有老师前辈们实现过手册中写到的2cm高度检测吗?目前英飞凌哪一款最适合动态情况下的gaos
我测量的高度大概都是在m级别变化,寄存器给的已经是最高精度的配置了。两块传感器,在同一个位置同一个时间上电,差别也十分大,想知道导致这种变化的原因是什么?以及在运动过程中这个气压计实际的相对高度测量精度究竟能够达到多少?
谢谢各位!
Show LessI am working on the pressure sensor (DPS310) for my study.
The time resolution of the sensor is around 4Hz which I would like to develop.
Do you guys have any idea to develop the time resolution of the DPS310?
It is ok to lose the accuracy a little bit after I fix the time resolution of the sensor.

If you have sample code for RF communication between SP40T and CMT2219B or code to read sensor values of SP40T, please let me know.
Thanks you so much!!!
In our factory, PCBA will go through water clean process.
Does Tire pressure sensor(TPMS) allow this clean process?
Hi Dears.
I want to read parameter from sensor by sending command through out I2C for the SP370 (900 kPs) In programming Mode.
I can read Temp and Voltage of Battery correctly. But for check Flash_erase Status, i can't get back right CRC from sensor!you can see my signals in below pictures.
For checking status i send the FLASH Check Erase Status and wait for 40ms and get the answer!!
I get the this Chars :{0xFF,0x03,0x5A}! what is that wrong?
The some thing is weird! All commands from my side that have no CRC (like getting voltage or temp or status) give me back right but in some command that i have to send CRC with, the answer is wrong?!
Thanks.
