LPG Cylinder – Continuous usage monitoring

In this post, we had talked about a continuous LPG monitoring system. We built an updated version of the system where we changed the base platform, and used a more rugged and sleek set of enclosures for the load cell’s PCB, and the WiSense node, respectively. A set of CAD renderings of the system is shown here:

We used ply-wood to build the platforms, and used enclosures made from ABS plastic. The system been running continuously for over a week now.

  3. how long does the battery last?

    • Sleep mode current consumption is in micro-amps, so battery life depends on how often you want to send data.
