Hello,

I am looking to interface and gas and water sensor to my BS2. Has anyone tried to interface such sensors? Any recommendations as to a what sensors might work with the BS2?

Thanks,

Waveman

Gas pressure? Water Level? Water density? Gas Spectrometer? Water Temperature? Gas as in CO2 detector?

You need to be a bit more specific as to what you want to measure.

Think Inside the box first and if that doesn't work..
Re-arrange what's inside the box then...
Think outside the BOX!

I would like to be able to measure water pressure and flow rate, as well as a gas flow meter for let's say air.

Thanks,

Interesting gas flow meter uses temperature sensing probes to measure heat loss in flowing air with Voltage output or pulsed output.
You may be able to rig something up from this. Using a voltage regulator that has a thermal shutdown feature can be used to detect very slight temperature variations in flowing air by monitoring the voltage output at the critical point of shutdown temperature as the voltage varies or moves exponentially in this area similar to a fets turn on/off point.

This is a good read on water pressure sensors. A strain gauge on a rubber tube can be used to measure water pressure. There is information on this site on strain gauges you can search for.
