Hi clan,
Hope everyone is doing well.
I've been contemplating an idea of building an early warning system, which will send an audible signal to the driver when the coolant temperature goes above normal. I think the device can be made relatively inexpensive.
Great idea?
Good idea?
Ok idea?
Nah, find something better to do.
Brutal honesty is much appreciated.

Sounds like a cash cow. I think it's a great idea.
I know a lot of us look at the temp gauge more than the speedo, but by the time you see it overheating, it's likely too late...

Pretty good idea!
The thing with newer BMWs is the coolant tanks get smaller and smaller, so by the time you see its hot, youve lost most of the little coolant it had. Older BMWs had much bigger tanks...

Great idea. The temp sensor range we have right now (the gauge), has a huge band in the middle.....so if it leaves the 12 O clock position...you know your in the sheeeeets and most don't catch it.

I would be very interested in this

Also interested.
What are you considering? Moving the sensor? Installing a process controller that displays a digital value and sounds an audible alarm once a temperature or temp rise is reached?

Awesome idea.

@billschusteriv - There are couple of approaches on the table. One thing I definitely do not plan on doing is an LCD readout of the temp. As soon as you introduce a display component the price and complexity goes up. In fact there are many products out there that will read out the temp from the ODBII.
Are you versed in Arduino coding?Originally Posted by nk_zhp

I have never done anything on that platform, but have seen a variety of project utilizing it. I can certainly see its application in this case.
