TPMS... DIY and Design Anatomy

[srt8-in-largo]

Interesting; I haven't considered an audible alert. I'm assuming you mean an audible alert in the bike's sound system.

When the receiver detects an alert status from the sensor, all it can do is turn on a signal. With an LED the process is simple; all that needs to be done is to use this signal as the power source for the LED. Receiver detects an alert... turns on a signal... the LED gets power and lights up.

However, even my digital multimeter generates little beeps when I press buttons on it. There has to be simple tone generators out there that can be used here. Receiver detects an alert... turns on a signal to power the tone generator... sound is created. Hmmm... yes I think that's a possibility! The output of the tone generator would just need to tie into the sound system.

Now that I'm past the hard part, these will be easy to make, and the more I make the cheaper I can offer them. I currently have these built on generic prototype PCB's from Amazon but for ruggedization for automotive use these will need proper PCB's made which are cheaper in higher volumes.

I'm not concerned about it coming thru the sound system, half the time I'm listening to the wind only. You could mount a small warning horn out of sight under the dash somewhere. I've seen these small horns in electronic stores.

I'm gonna look into this. Thanks for the idea; it's a good one.

Audible warning through a 3.5 jack at set below normal tyre pressure would be excellent

SRT8 - your doing great, your project is going to be a hit! Positive enforcement always speeds up production!

With the design completely in my control, anything is a possibility!

I really appreciate that FLA; I won't say how many all-nighters I've pulled trying to get this going. I have parts for the sensor in hand and ordered custom PCB's last week.

I still say a small warning horn separate from the sound system. But who am I to say? You're the one staying up all night! Thx for working on this.

You're now the 3rd person to cast that vote... so I think a horn is "sounding" good

Would it be simple enough to run the LED trigger to a relay to activate the factory horn?
Might scare the hell out of you but it would get your attention quick enough for a catastrophic tire failure.

That's actually a brilliant idea Ted.
