I have a mid 80’s Honda Sabre motorcycle, and the gauge panel is severely broken. I was able to salvage everything except the speedometer. The parts for it are no longer available, and used parts are sky high in cost when available, plus they’re 25 years old. The bike uses an electronic speedometer & tachometer, along with a digital display that had LCD gear positions (via 7 wires- one for each gear and neutral), fuel level, and water temperature. The bike predates the engine control modules and data bus setups of newer bikes- it’s fairly old school. The wheel speed sensor uses a three wire setup: an 8V input from the dash, sensor ground, and outputs 0~4 to 8V back to the gauge per the shop manual. I’ve looked at late model bike dashes, and many use CAN BUS setups that I’m unfamiliar with. Some older ones still uses similar sensor data as what mine does, so they are a possibility, but I’d have to add-on gauges to monitor all the things I want to monitor. I’ve looked at dashes (via wiring diagrams & shop manuals) from all the Japanese models as well as Aprilia, Buell, Ducati, and Triumph and even a couple of snowmobiles. All are either lacking a feature I want or they cost way too much. What I’d like to do is hijack a later model dash with an LCD panel & make it display the stuff I want… but I digress.

I found some LCDs with built-in serial graphics here. I downloaded the software tool and have been learning how to use it. Of course, I’d need either a waterproof LCD or secure casing for it/them. I have a basic understanding of electronics, and the ability to learn about things- I’ve self-taught myself things such as welding and AC repair.

I’d like to build an Arduino project to drive an LCD (or possibly 2, speed & RPM). What I’m planning to monitor is as follows, along with my comments:

I don’t need fancy displays on the LCD, just numbers & letters. I drew a prototype using some software and have attached a JPG of what I’d like to end up with (single screen).

However, using the HC-SR04 outside is a different story. It is a pretty fragile device and can easily be damaged by dirt, or even high winds. And, above all, it is not waterproof.  Even sealing up its circuit board would not protect it, as the two transducers it uses are essentially just small speaker/microphones.

The A02YYUW is an ultrasonic distance sensor that bears some resemblance to the HC-SR04 in that it has a separate receiver and transmitter.  The device is enclosed in a rubber-like material and is fully waterproof.

If you need an ultrasonic distance sensor that is waterproof, then either of these units would make an excellent choice.  They both performed well, and they are rated for harsh environments.

They are, however, more expensive than the HC-SR04, so if you don’t require a rugged waterproof sensor then the latter is still a more economical choice.

Learn to use the JSN-SR04T and A02YYUW waterproof ultrasonic distance sensors with an Arduino. In this article, you"ll learn how these sensors work, how they compare to one another, and how to use them with an Arduino.
