Hello,
I am building a data logging system for my senior design project. I was wondering how many channels I can log with the current data logging shield?
Thanks,
Emma

Re: Data logger shield
That depends on what type of sensors you are using. With analog sensors on an Arduino UNO or similar processor, there are 4 analog pins you can use. With SPI or i2c-based sensors, you can potentially bring in many more channels of measurement.
What are you measuring and which sensors do you plan to use?

Re: Data logger shield
I intend to use 3 axis accelerators and 3 axis gyroscope and possibly a load sensor but I'm not sure about that. The outline of the project is test the crashworthiness of a low speed vehicle so I will mount the sensors onto the chassis and read the measured force experienced during the test.

Re: Data logger shield
You should consider one of our IMUs. These contain 3-axis accerometers, gyros and magnetometers. They use an i2c digital interface, which they can share with the real-time clock on the logger shield.
Load sensors require an instrumentation amplifier. These are available with an i2c interface as well.

Re: Data logger shield
I'm pretty new to all this so just so I'm clear: you are suggesting I use both the IMU (10 DOF,ect) in addition to the logging shield?
Thanks much

Re: Data logger shield
Yes. The IMU has most of the sensors you need and is compatible with the logger shield. The 9DOF IMU should be sufficient. The 10DOF adds a barometer, which does not seem to be a requirement for your application.

Yes, the 9DOF seems sufficient. Thank you so much for your help and I'm sure I'll be back
