Design Specifications

The SWEETSense™ Technology combines commercially available front-end sensors, selected for specific applications including water treatment, cookstove, sanitation, infrastructure or other applications, with a comparator circuit board that samples these sensors. The comparator boards monitor the sensors for trigger threshold events that start and end periodic local data logging. The stored events are coded to reduce the amount of data and the amount of energy required for transmission. The measurements are relayed directly to the internet via GSM or Wi-Fi. If there is no internet connection, all of the data is stored on an SD storage card. Data processing is enabled on the internet-based software program SweetData. The SweetSense package includes: • 15 sensor inputs – 8 contact, 7 analog to digital • 5 AA batteries • SD card backup • Enclosure The SweetSense standard package measures 12 cm x 8 cm x 4 cm [caption id="attachment_22975" align="alignnone" width="300"] FLOW data visuals[/caption] [caption id="attachment_22976" align="alignnone" width="258"] SWEETData platform[/caption]
