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.

Temperature-Sensing Coffee Coaster

Coffee is taken very seriously here at Digilent, as it is in most workplaces. Something that used to make me mad was not knowing when my coffee hit that perfect “Goldilocks” temperature zone where it didn’t burn my mouth but was warm enough to fully enjoy. I am currently working on developing a thermocouple Pmod using Analog Devices MAX31855 and thought of a great application project. If I could somehow sense how hot the temperature of the coffee was, I could have a microcontroller tell me when my coffee hit the perfect temperature range!
