SmartPressure™ MEMS Pressure Sensors

Hi, We are using ICP-20100 pressure sensor and calibrated wrt standard reference sensor. At room temperature we are getting good accuracy throughout the range but when we are placing it in a control temperature chamber, the barometric pressure is varying with respect to temperature. Hence, Altitude is not stable.
How can we improve it or compensate temperature variation.

Hi,
We are looking at using the ICP-10125 in our application, the liquid that the user consumes could potentially come into contact with the gel and chimney of the ICP-10125 pressure sensor.

Q1. Are you able to provide the material details of the silicone gel and stainless steel chimney?

Q2. Does the stainless steel have any coating/plating?
We can then check to see if the materials are food grade so we can use in our application for production.

Thanks

we are currently using icp 20100 sensor with i2c communication protocol, but we're not able to read the device id properly it keeps on changing. Is there any important step that i've missed during init or during reading device id?
can anyone please explain the steps for init or tell what's the problem I'm facing.
thanks and regards.

Hi,
I'm currently using ICP-20100 for my project which requires interfacing with ATSAMD51J20A ,so can you please share me the sample code for the same!

Thanks and regards,

We are evaluating an ICP-20100 connected to an STM32 via I2C. The I2C clock speed is 100kHz.

The ICP-20100 will only return zero values in response to read requests. For example, reading address 0x0c (DEVICE_ID) returns 0x00 when it should return 0x63. All other read requests return zero as well.

The I2C bus appears to be operating properly as we have other sensors on that bus which work correctly. In addition, we have observed the SDA/SCL signals on an oscilloscope and the ICP-20100 is responding with ACK signals as expected, but all data values are zero.

Hello. We have the product coded ICP-10101 on our card. We receive some errors when we run our product. We are experiencing problems in mass production. While some sensors work fixed and stable, some work very differently. While the device that measures correctly shows the value 1004, devices that measure incorrectly can measure the value 850. Especially the sensors that read incorrectly change a lot instantly. When we debugged faulty products, we saw that the value read by the sensor changes as the temperature value changes.

Is there a equation of ICP-20100 OSR or minimal ODR?

I am working with two small evaluation boards for the ICP-10125 and the ICP-20100; however, these are not the ones shown on the website (which are bigger and with more components).
Mine are smaller and I cannot find any documentation about them. Does anybody know where can I get any data sheet, manual, or application notes for these two development boards?

Hello. I have ICP101xx ICs. I have developed the software related to it. It works normally without any errors. But when the card with the sensor starts to shake, the value suddenly deviates. When you play 1 meter up and down quickly, there are huge differences. What is the reason of this? Is there anyone who can help?

It seems not be possible to activate IIR Filter in Mode4 Config1 Register over the Motionlink 4.2.6 user interface. Values >0x1f were limited to 0x1f
Has someone the same problem?
