Hello,
I would like to make a prototype anaerobic digester and would like to monitor the gas pressure. Could someone recommend a gas pressure sensor for a sealed vessel in which microorganisms produce gases? I am considering Qwiic Pressure Sensor - LPS25HB or Pressure Sensor (Qwiic) - MS5637 but didn’t know if there was another product more suited for such an application?
Thank you,
Brock Baxter
Hi Brock.
Both of those sensors are designed for measuring barometric pressure rather than pressure in a sealed vessel and both would probably max out pretty quickly in your application. The closest thing we have that might work for you would be the [MS5803-14BA but you’d need to find a way to protect the PCB and electronics from and liquid or vapors in your system.
If you can locate a sensor that threads into your vessel from the outside, that would probably be ideal, but unfortunately we don’t carry anything like that.](https://www.sparkfun.com/products/12909)
Thank you!
