Hi All
I am Building a Home made ROV. Lockdown give me more time to do stuff. I have a couple of questions please. First how other, finding out the depth of the ROV. Second recommendation for a digital compass. I am using Arduino nano for sensors, and second Arduino nano for control, over Ethernet network.
Thank Dave

Re: New to here, and have some questions
Buenos días.
En cuanto a la profundidad, depende mucho de los materiales con los que realice su ROV.
Con tubos de PVC, plástico de fontanería, los compañeros dicen que bajan hasta 100 metros de profundidad. Yo personalmente, no me lo creo.
Si usted utiliza metales hierro o aluminio, para realizar el casco, puede bajar a mucha mas profundidad.
Y otra cosa.
Yo creo que los Arduino Nano, se quedan cortos en cuanto al numero de pines para la conexión de sensores.
Si usted solo va utilizar la brújula digital, el Arduino Nano, le puede servir.
En el momento que usted quiera poner mas sensores, sencillamente, no va a tener espacio físico para conectarlos.
Yo le recomendaría el uso de los Arduino Mega 2560.
Hay muy poca diferencia de precio, y una gran diferencia en cuanto a posibilidades.
Un saludo.
Good morning.
In terms of depth, it depends a lot on the materials with which you make your ROV.
With PVC pipes, plumbing plastic, colleagues say they go down to 100 meters deep.
I personally don't believe it.
If you use iron or aluminum metals, to make the helmet, you can go down much deeper.
And another thing.
I think the Arduino Nano fall short in terms of the number of pins for the connection of sensors.
If you are only going to use the digital compass, the Arduino Nano, can serve you.
The moment you want to put more sensors, you simply won't have physical space to connect them.
I would recommend using the Arduino Mega 2560.
There is very little price difference, and a big difference in terms of possibilities.
Greetings.

Re: New to here, and have some questions
Hi there
Thank answering my questions. I am aware of limitations of the arduino nano, I try keep the size down, this project is I want take around the world with me, I Scuba dive. I using 2 nano one for control, one for sensors. Which digital compass do you think is the best. Also my question on depth, was how do you get sensor to get the depth, I think a pressure sensor, but can’t find one that can do the job, just checking I was not missing any thing.
Tell me about your ROV… how are things by you… world is not a nice place at the moment.
Thanks Dave.. hope you and your family stay safe.

Re: New to here, and have some questions
Hola buenos días.
Por aquí estamos bien de salud, espero que tu también lo estés.
En cuanto a la brújula digital, yo estoy utilizando un GY MPU6050, es muy fácil de incorporar y tiene muchas posibilidades, es un giroscopio digital de 6 ejes, que tiene incorporado un sensor de temperatura, en este enlace te explica como funciona.
https://www.electronicshub.org/getting- ... o-mpu6050/
En cuanto al sensor de presión, "Houston, Tenemos un problema".
La electrónica y el agua no se llevan bien, por lo tanto, olvídate de la mayoría de los sensores de presión para Arduino.
Pero tienes una alternativa, que es utilizar un sensor de presión de aceite que se utiliza en automoción, se llaman Sensor de Presión SKU237545, en este enlace se explica como funciona.
https://create.arduino.cc/projecthub/Fi ... ing-42189b
Te adjunto un código que yo hice solo con el control del sensor, porque no me hacia falta todo lo demás, ni la pantalla LCD, ni la Tarjeta SD, ni nada de todo lo demás que se explica en el proyecto.
Puedes ver mi proyecto en este enlace.

Hello good morning.
We're in good health around here, I hope you are, too.
As for the digital compass, I am using a GY MPU6050, it is very easy to incorporate and has many possibilities, it is a 6-axis digital gyroscope, which has a built-in temperature sensor, in this link explains how it works.
https://www.electronicshub.org/getting- ... o-mpu6050/
As for the pressure sensor, "Houston, We have a problem".
Electronics and water don't get along, so forget about most pressure sensors for Arduino.
But you have an alternative, which is to use an oil pressure sensor that is used in automotive, they are called Pressure Sensor SKU237545, this link explains how it works.
https://create.arduino.cc/projecthub/Fi ... ing-42189b
I attach a code that I did only with the sensor control, because I did not need everything else, nor the LCD screen, nor the SD card, or anything else that is explained in the project.
You can see my project in this link.

Re: New to here, and have some questions
You can also put a scuba depth gauge and a cheap automotive ball compass (for the dashboard) in view of the camera on the ROV. Poor man's solution.

Re: New to here, and have some questions
For a depth sensor I use a Honeywell PX3AM1BH100PSAAX
and my compass is a CMPS12 from Robot Electronics.
both are excellent sensors.
I also use two nano's, one for topside control and one in the rov. they suit my rov perfectly due to their small size.
in fact I replaced my rov nano with a bare Atmega 328p chip to save even more space.
if you use I2C sensors you can connect several on the I2c bus so you aren't limited.

Thanks for your information. Like the Houston we have a problem... quote. I think that going to go with the CJMCU-MS5540C designed for us underwater, it’s good for 100 Meters. I send some information over on my specification of my ROV.. focused my interest on control and sensor. Waiting for parts to come, then I can get my thrusters sorted. At the moment my ROV is a load of bits on my desk....
Look after yourself and family. Best regards Dave
