Smart Irrigation System

During the summer, gardens abound — so many people are keeping an eye out for their sun-ripened, home-grown tomatoes or for that lovely hydrangea that’s just the right shade of blue. But summers are also a very hectic time. So how do you maintain that garden and make sure it receives the care it needs? One of the projects created for the Digilent Design Contest 2015 is a smart irrigation system intended to work with an Android device to see to it your garden gets the moisture it craves.

SPI with chipKIT WF32 and LabVIEW

I have recently been working on SPI and I2C with the chipKIT WF32, LabVIEW Home Bundle, and various Pmods. Using LabVIEW MakerHub LINX, I was able to have the WF32 interface with the different Pmods and LabVIEW. I wrote an Instructable here about how I got the PmodALS (ambient light sensor) to interface with the WF32 which also includes a section on how to read the data sheet to find what you’re looking for. This Instructable was made as a guide so that others can understand how to read the data sheet in order to find the information required to use SPI for various sensors themselves.

Digilent Pmods: Input Pmods – Sensors

It is time to check out another set of the Digilent Pmods! Last time, we looked at a subset of the input focused Pmods, the analog-to-digital converters. Today, we’re going to take a look at more of the input Pmods, most of which incorporate ADCs into their design structure. These ten peripheral modules are all inherent sensors, reporting the temperature, location, light level, or movement without the user needing to physically interact with them.
