I am looking for an IMU module to mount on an R-Theta-Z type robot (on the end effector), used for semiconductor wafer handling, similar to this one - Products | GCR4280 (For 300mm wafer) | Wafer Transfer Atmospheric Robot, to monitor its movement and vibration. Can you suggest which of your modules would be better for this type of application? I… (Show more)

On our ADIS16490, the factory bias calibration for two of the gyro axes seems to be completely wrong. After doing a factory calibration restore, if the IMU is standing still, and we plot the outputs, one of the delta angle outputs is close to zero, and the other two are way off, apparently close to the numerical limits of the integrator, so if we… (Show more)

Hi, I have been using the ADXL213 in a low volume, specialist hobby application that has been working well across the world exposed to the elements and wanted to build a new batch of 5 units but was shocked at the ~$35 price.   I need help finding a more cost effective accelerometer for this application: Operating temperature: - 40degC to about… (Show more)

I'm developing a board using the adxl1002 accelerometer. I collected a lot of points using a reference accelerometer as a base and the measurements that the accelerometer are presenting to me are not according to the datasheet. Has anyone had the same problem? The curves are attached.

I'm using an ADIS16223. My code to read the X, Y and Z buffers is just returning 0xFF for each byte, but all other reads and writes seem to be working. Any idea why I am having trouble getting acceleration data from the X, Y and Z buffers?     Here is my code:   //============================================================================== //… (Show more)

I found the ouput data is negative when the gravity in positive direction as follow. Can you confirm it ? or something wrong in my operation?

ADXL375 we are working on our first application with it and wanted to know if there are any major effects on its reading of vibration and shock detects if it was completely potted?

Hi engineer team,   I was looking on the ADXL1002 datasheet and I was wondering about something : is that significant and accurate to measure a voltage difference which is less than 2mV or 1mV with the ADXL1002 ? We know that the sensitivity is 40mV/g, and the ADXL1002 is made for a huge range +/-50g, so basically the main purpose is not to… (Show more)

adis16448 The data  changes very slowly when reading ADIS16448AMLZ inertial data via SPI at 200Hz sampling frequency. The microcontroller I use is STM32F103. The data is abnormal When I download the program to the microcontroller and then open the module's switch to drive the ADIS16448. As shown in the figure below. For example,the data from… (Show more)

I am having intermittent issues with both the ADXL355 and ADXL357 accelerometers (we use them interchangeably due to stock issues). The issues manifest as one of three problems: All three outputs sit at zero One output sits at zero All three outputs have large bias errors (> 1 g). The issues are usually resolved by power cycling, although… (Show more)
