What is the best internal Temp sensor can works with the Navigator?

I want to measure the temp inside the enclouser using any kind of sensor which can be connected to the navigator and works with Ardusub without coding?

Hi @elhedody, welcome to the forum :slight_smile:

Where and why are you wanting to measure the temperature?

The BMP280 sensor onboard the Navigator already provides temperature in the SCALED_PRESSURE MAVLink messages, and the BlueOS System Status shows the onboard computer’s CPU temperature.

If you need the temperature from somewhere else in the enclosure then I suppose the simplest approach with automatic ArduSub integration would be to use one of our Celsius PCBs, but you’d need to solder on the wires yourself.

Hi @EliotBR

Thank you for fast reply.
Actually I will be using 2 M200 motor for brushes underwater which will be working 10-20 min continuously. So I am worry that the interior temperature inside the enclosure will be too high and will lead to a failure. The escs will be connected to heat sink and touching the aluminum enclosure.

So do you think the sensor integrated in the navigator is enough ? Or should I add other sensors?

Many thanks

If you’re using our BasicESC they have built in thermal protection, that reduces the output throttle if they get too hot.

If you’re worried about the heat from the ESCs causing the other electronics to overheat and reduce the system performance/control then you could set up a warning using the internal temperature failsafe (via Vehicle Setup / Configure / Failsafes, in BlueOS) to tell you when the Navigator gets to a temperature you’re concerned about.

Thank you for your support, yes I have your escs I will setup failsafe as you mentioned.

Thanks again
