Regal 2250 - Remote boat monitor

by mlines » 31 May 2015, 19:19

Wet weather playtime, start of a remote monitor for the boat using an Arduino. The intention is to eventually create a little boat installled computer that reports back via the internet various status reports.

This is the initial build with a display added and a small temperature sensor, you can see I use my body temperature to raise the sensor temp and set an alarm to red. I have a GPRS module in the post to get the "remote" part working next.

Intresting project, Keep the updates coming,

Intrested in what the unit will report back.

It will report anything you like. Its a microcontroller to which you add sensors and programme it. So it can report anything from battery condition to motion (g force) speed , locations, fluid levels

I've done a lot with this. The arduino are great mini boards, and get quite good fun with gps and accelerometers etc. Looks like you are using a single wire DS1820 temp sensor?

One thing for a boat is its worth looking into sleep and power management. That way you can massively extend battery life. I'll be keeping an eye on this are you going to get a sim/GPRS module as well?

Ed - in the video its an LM35 sensor. However this does not go below 0 Centigrade and although you can see the test alarming at a warmer temperature, the real interest is to watch for freezing temperatures. I have the digital humidity/temperature sensor 2302 but the supplied library crashes the compiler at the moment, so that work in progress.

I am waiting for the GSM/GPRS module to arrive in the post, they are cheap as chips from China.

Power management will be essential in the finished version. It will be running on shore power and will alert when it detects a change over from shorepower to battery (i.e power fail). However I am talking to a Microcontroller expert at work about putting the chip to sleep and waking it up on a timer or an external event input (movement sensor?)

There are some libraries which mean the remote Arduino can feed into Google charts so the status can be seen from an Internet web page with the data fed in from the Arduino - I like the gauge chart and can feed temp/humidity to this with an SMS text on reaching an alarm limit - https://google-developers.appspot.com/c ... lery/gauge

That's better, now found a library that will compile. I can add in humidity as well.

Next is the GPRS card but this is more difficult as I notice it shares an I/O port with the LCD card :(

Very impressive, very useful bit of kit that!

Of course after you start a project you find someone has been there before!

The Scooterputer - http://www.janspace.com/b2evolution/arduino.php

He uses a different (and much fancier display card) which does not clash with the GSM card so my project may become "heavily influenced" by this design ;)

And there are some out there which let the owners where there boats are moving too.

Yours lets you know all sorts of other information, keep at it! :D

Well the gsm card has arrived today. An accelerometer, real time clock and GPS is on its way. This will give me 3 axis motion detection, location and an accurate timestamp
