Overview

The Riffle is a collection of designs that take an open source approach to water monitoring, with the intent of making gathering water information easier and more accessible. (For an overview of the design philosophy behind the Riffle, see this wiki page).

The first Riffle design was an ARM-based datalogger board enclosed in PVC; Public Lab has supported development of an Atmel328-based datalogger enclosed in a water bottle.

Water Monitor Designs

By now, several instrument designs have been constructed around the Riffle, some of which of are described in an array of Github repositories:

• Openwaterproject -- the main organization on github
• riffle_328 -- hardware designs, instructions and software for getting started with the Riffle_328 datalogger
• riffle_328-conductivity -- Design considerations around conductivity
• riffle_328-depth -- Depth measurement circuit prototype
• riffle_328-turbidity -- Turbidity sensor prototype
• riffle_328-thermistor -- Connecting a thermistor to a Riffle
• riffle_328-i2c -- Connecting i2c sensors to a Riffle
• riffle_328-one-wire -- Connecting one-wire sensors to a Riffle

Sensor Designs

We've started to summarize some of the approaches to sensing water parameters like conductivity and turbidity:

• Sensing conductivity
• Sensing turbidity

Project Status

• 2016 Riffle_328 Status. A small order of Riffle_328 boards arrived late April 2016, and were sent to Public Lab community members as a ways of testing current hardware features and direct further development.

The Riffle

The RIffle_328 is an Atmel328-based variant of the original ARM-based Riffle water monitor, which was designed by Ben Gamari and Laura Dietz. The Riffle_328 is designed to be programmed just like an Arduino UNO in the Arduino IDE, and is compatible with most Arduino UNO software libraries. Hardware designs for the Riffle_328 are released under the CERN Open Hardware License v1.2.

Public Lab's Open Water Initiative has supported development of the Riffle_328, as well as several water monitoring sensor prototypes.

The width and height of the Riffle-ito device allows the device to fit through the mouth of a standard commercially produced plastic water bottle (20 mm). By inserting the Riffle-ito into such a bottle, along with a few AA batteries, and connecting a thermistor and other sensors that poke out through the water bottle cap, a very accessible water quality sensor may be constructed.
