Hello,
I’m absolutely, completely new to this and I need to design a system where I attach a GPS, accelerometer and pressure sensor to an object, and record its position at all times, and then process the data using a datalogger. How would I go about this? Could I just directly connect it without an adruino? Any help would be more than welcome!
Thank you!
Could I just directly connect it without an adruino?
No, because accelerometers and pressure sensors all require a microcontroller of some sort to read them out.
The SparkFun OpenLog works well to log GPS output directly, and would work well to log the output of an Arduino reading an accelerometer and pressure sensor. To do all three at the same time is a bit of a challenge as you need two serial ports, one for the GSP and one for OpenLog. Nevertheless, if you take it one step at a time, it is doable.
Another option is to use an Arduino with an SD card shield to log all three devices.
