Are you in a Bind?  The poor documentation can make things seem more complicated than they really are. Getting an Raspberry Pi output pin working on OpenHAB is actually much easier than you are led to believe.   Here's a quick example on how to get an LED and current limiting resistor connected to Pin 11 (GPIO17) up and going. All one needs to do is to; 1. Ensure that the GPIO is not exported and used by another process. 2. Connect the LED and resistor. 3. Copy the gpio binding ...
In this post, I will face a difficult challenge: detect whether a plant is flourishing or not. At this moment in time, this feature requires some more experiments and works to make a reliable solution, but I think the solution is promising NDVI Vegetation is green because plant leaves reflect green light -- they don't use much of it for photosynthesis (see Figure 1).   Instead they use lots of the blue and red wavelengths in sunlight. The pigments in leaves absorb this light to power phot ...
This is an update to my Forget Me Not Design Challenge project. It is delayed because of a week lost to a trip, two weekends lost to softball tournaments, half a dozen hockey games and the process of landing a new job. Also, I am still struggling to get the parts I need, but I have enough to show some progress. Enocean provides fairly straightforward software for monitoring their sensors and several of the contestants have provided excellent instructions on how to get such systems working with ...
