In June 2015 the site was equipped with an RX3000 remote monitoring station to deliver rainfall and streamflow data via telemetry. In addition, a trial was performed with SMART sensors for high frequency measurement of water quality variables in the Baru stream.

Our Infrastructure and Sensor Deployment
The following images give an insight into the SMART sensor system set up at the Baru watershed:
i::scan probes (35mm and 5mm pathlengths) with autowiper mounted with ph::lyser for installation in Baru stream behind v-notch weir. Measurement interval was every 5 minutes.
con::cube controller for data acquisition (from i::scan and ph::lyser) and sensor interrogation secured in waterproof box with power source nearby to stream. High power consumption required change of batteries every 3 days.
