I’m about to start a project to build something that monitors air pressure, and passes defined values off to a mail server for delivery to a person’s email.
This setup would be tied into a pressurized air line, so you could think of it as monitoring gauge pressure. My initial thought was to have a photon reading values from a surface mount air pressure sensor with a male barbed port for the air line to be attached to.
If anyone has suggestions on a different approach or know of a better way, I’m all ears.
I would suggest replacing the photon/arduino with a Raspberry Pi. The use of a full computer (the pi) would allow you to create the hardware and position it where you want it, then ssh into the computer and be able to develop and modify your code as your project progresses. I believe it would also be cheaper.
What units of pressure? Meaning psig, inwc,etc. Also what range? I bought some pressure sensors a while back from Amazon. The range I am personally using is 0-200 psig with a .5-4.5 vdc signal.
@wandrson I’ll look into the pi approach, but you can connect to photons in various ways, flash code, read values, etc., just like the pi. I think it would also be cheaper. Photons are $19.
@TBJK The units are psi. The range is 0-150. How did you tie in the pressure line to the sensor?
Since you subject said arduino/photon, I was assuming you were using both, which would cost as much or more then a PI. That said I know nothing about the photon. Good luck with your project.
There are many ways to tie a line in for pressure. It all depends on what you have existing or what your looking for. You could use compression fittings on copper tube, flare fittings, hose. Cheapest would likely be compression fittings with copper tubing.
