I have built several prototypes that require testing in the UK before being deployed into field trials in Kenya. | |||
This project aims to develop testing tools that can be used in a ‘lab’ setting in the UK to gather benchmark performance data before being modified to work in a field setting to gather ‘real world’ data. | This project aims to develop testing tools that can be used in a ‘lab’ setting in the UK to gather benchmark performance data before being modified to work in a field setting to gather ‘real world’ data. | ||

==Progress== | |||
===26th April 2011=== | |||
Work completed: | |||
* Data logger shield built and tested, RTC and SD card both working | |||
* Built 18-bit ADC breakout board | |||
Next steps | |||
* Figure out how to connect the 2 pressure sensors to the ADC | |||
* Test the ADC/Data logger combination with a known analogue input (figure out how much noise there will be on the circuit - what resolution we should expect) | |||
* Write Arduino program to run the test | |||
* Hook up pump/filter and tubing to run first tests | |||

To drive the filtration system in a lab setting I’ll also need a heavy-duty motor, drive train and a frame to keep it all in place. | |||
==Expertise== | |||
I'm happy to work with other hackers on this project, especially those with an interest/expertise in: | |||
* International development (specifically water and sanitation) | |||
* Using any of the hardware listed above | |||
* Running field trials/Lab based testing | |||
==Future Plans== | |||
* Expand the data logger to accept other sensor modules, to enable open-source field data collection | |||
* Development of an open-source water quality (physical/bacteriological) testing kit for field work [[See Project:Water Quality Test Kit]] | |||
