Thread: Arduino Modular Engine Sensors Unit (~$50)

I'm still interested though no longer for a disco I upgraded to a perentie so dash space is at a premium I wanted to purchase one of the 5 channel temp sensors from the shop on this site but when I got around to it they had sold out so currently might have to dig this information up again and work on a temp sensor arrangement to keep an eye on things.

Doesn't look like Hayden has been around here for a while, but was wondering if anyone is currently playing around with Arduino gauge projects.

After some cold nights and a recent thread on the 1Gauge (http://www.aulro.com/afvb/communicat...questions.html) I decided to dig out my dusty box of Arduino bits (mainly a Arduino Uno, 16x2 LCD shield, and some DS18b10 one-wire temperature sensors).

If progress stays ahead of the enthusiasm decline my plan is to put together a data logger for the county with

• A few DS1820 temp sensors for head temp
• RPM
• K type thermocouple inputs for EGT and turbo compressor temp (since they'll exceed the 127degC limit of the DS1820's)
• Speed
• Battery voltage (just because its easy!!)
• SD card for logging
• Display of the various values
• Visual and audible alarms

So far I have working setup for 3x DS18b20's and a functioning frequency meter with optocoupler isolated input to take "W" wire output from the alternator (already have the W wire installed and currently drives a normal VDO tacho).

Does the County need such a logger?
No
But that's not a good enough reason not to play around and make one

My enthusiasm curve turned out to be inversely proportional to time.

I look forward to your updates tho!

Time spent, available or just elapsed??

Seems Hayden is still doing Arduino stuff, but no longer able to post in tech sections http://www.aulro.com/afvb/showthread.php?p=2574629

Best I start my own thread rather than continue to hijack this one...

Bit of a thread Resurrection here, but I've got a micro-controller based gauge system in development...

It started out life on Arduino Nano, but I rapidly ran out of GPIO & memory so it's now moved onto STM32 (32bit 76mhz vs 8 bit 16mhz).

All the code is here -> GitHub - BennehBoy/LRDuino: In car multi gauge system - Arduino, 0.96" SPI OLED, MAX31856

I've got one of my early Uno based prototypes in my TD5 Disco:



It turns out that 8 of those OLED screens fit perfectly in a CB cutout so I've upsized the bench test system. It now has a digital inclinometer with animated vehicle images, and it also will display readings from an ELM327 type OBD dongle via Bluetooth.



The screens are not blurry at all, my phone cam just doesn't like taking pics of them.

I'm currently porting Luca72's (the guy who wrote td5 map editor) td5 opencom to the same microcontroller, it provides a cut down version of nanocom. Datalogging to SD card, fuelling info, fault reading & clearing.

You can see it running in instrument mode here, it's hooked up to an Arduino Uno which is running as a basic td5 emulator. I'm using a logic analyser to sniff the serial connection between the two, it makes life a lot simpler.


The idea is that I will then integrate this into my multi gauge system.

Just saw this thread and am very interested in these type of projects, always looking for something like this at an affordable price for the ute, as well as possible projects for the bike 'just because'.

Oh and I have a Defender so just in regards to the above pic, I don't need that 102 mile per hour bit....

Yeah it's a bit optimistic even for my D2 - big tyre's and lot's of offroad toys

Great project. Im start to look at arduino to get information from the ECU. This info is very good.
