In this paper, we describe the designed and tested system of automated double ring infiltrometer (DRI) that we
have developed using an Arduino microcontroller, a Hall effect sensor, a peristaltic pump, a water level sensor,
and a constant-level float valve. The system can be used for infiltration measurements in both single ring falling
head and double ring constant head methods. The precise measurements of the current method compared to
previous designed systems are not affected by sunlight, and due to themethod of flow measurement, remain accurate
even for lowinfiltration values. The set-up has an easy real-timedata storage on a micro-SD cardwithout a
need of a portable computer in the field. It only requires a single reservoir for both inner and outer rings towhich,
water can be added anytime needed without affecting the measurements. The system automatically detects
when the steady state infiltration rate is reached and concludes the testing and stopsmeasurements. The system
is mounted in a portable and weather resistant box and is applied to run DRI testing in the field to check the applicability
and accuracy of the portable set-up in field measurements. Manual testing was also performed in the
field for comparison with the automated system measurements. Overall system architecture, and the design of
hardware and software components are presented in details. The system configuration is illustrated for better
understanding of the set-up.
