Abstract
The Smart Rock is a submersible sensor suite that monitors temperature,
pressure (water depth), turbidity, and electrical conductivity. The
sensor suite can be deployed in streams for 3-6 months at a time taking
data every 20 minutes. The frequency of data collection can be changed
which will affect battery life. Smart Rock assembly has been streamlined
to make assembly and programming as accessible as possible. We want
water sensing to be affordable and accessible to water scientists around
the world. Our goal with the Smart Rock remains to develop an
affordable, user friendly, low cost, and accessible for our different
users needs. For those familiar with previous versions of the Smart Rock
let me cover what has changed with this latest revision. We have
designed our own electrical conductivity sensor with increased control
for the user to change the range and resolution of the sensor. The
enclosure has shrunk with a new selection of batteries doubling the
capacity of the previous version’s battery. We worked on stabilizing the
code and simplifying the operation. You can now control the unit’s
settings via a config file on the SD card. No more Arduino reprogramming
to change settings.
