Please let me know how you might want the specs. r-4-input/ for a USB sampler)ĭex, thank very much for your offer. the fun part was interfacing thermocouples for the cylinder head temperature and the exhaust gas temperature.

Some more advanced monitoring of the fluid levels and such require some interfacing but its not difficult. r-ds18b20/įor fuel consumption, I used a RS Components fuel flow sender (quite expensive but worth it) to a custom board that counted the pulses although I think the Pi can do it. 0-adxl345/įor Temperature sensors, these work a treat (1 wire digital thermometers that can be connected in parallel).

I built a non-pi and non race datalogger using a cheap £0 ELM327 based bluetooth systemįor some funky accelerometers, you can use the 2 axis accelerometer which can interface to the Pi using I2C (4 wires and it will work). Better/worse doing something with more off-the-shelf versus home-cooked? I am thinking longer term support, development, etc., but the appeal of Dex's 'InstaBoot' and other points about talking directly to the hardware also make sense. What I don't know is what to do with microV sensor outputs if we run across that, or whether there is any standard for this sort of thing.ĮcoRi, DexOS, speak up on how you might see this progressing. It takes inputs of +/- 10v, so all sensors would need to be in this range if using this device.

The Dataq 145 gets power via USB, transfers a stream northbound that has to be captured by some computer, hence the place for the Pi or other system like it (Shiva, etc). GPS position (for calling in airstrikes on your competitor's car. Flow, liquid and air at temperature (aarone's request) Position (multiple, ecoRi, Rogerw, others) Rotation speed/direction (multiple, ecoRi, Rogerw, others) Let's start collecting info on sensors for the following, and folks, add in as needed. I know what I need, but you race folks, sailboat folks will have a different set of needs. But maybe Dex is talking about both the sensor aggregator and data logging in the same device. Sensors->Dataq 145 aggregtor ($29) ->RaspberryPi running Splunk as a data logger, or with DexOS capture built from the ground up. Being a bear of very little brain, what I think I know is this: I just talked to the Dataq people, just trying to frame out how all this fits together.

Seems you need some device to interface multiple sensors. But if it is already built in Splunk.ĭex, how would you deal with multiple real-time sensor streams?

(I'm a splunk admin by day at my company so I'm certainly down to help out on that end if anyone has any log data they can send me I can work with)īy the way the DexOS site is way cool, too, and may be a way to deal with data logging. If your not familiar with splunk check out which is something they did for the 2012 elections kinda a show and tell to the nation on their software.

While I havent gotten to the point of getting hardware together and attempting anything on that end, I have been developing a backbone of a splunk app (still in the ui phase at the moment as i have no data to parse) to run analytics against the log data that way all a person needs is the logs dump them onto any computer and using an open source software (when using the free license which is fine for personal non enterprise use) can view and trend their data. esp now that people are monitoring everything from home security to their thermostat with data loggers and managing them from their smart phones as well as trending data in the case of thermostats. You know I hadnt really thought about it that way but roger I think your right, as we all tend to get more and more into monitoring our machine data the idea of a generic data logger market for cheap is prob a real one indeed.
