Product Description

The SWEETSense sensor technology package combines commercially available front-end sensors with a comparator circuit board that samples at a high rate and relays logged data events directly to the internet via GSM or Wi-Fi.

Data processing and visualization is provided via a supporting, internet-based software program, SWEETData.

The SWEETSense technology can be customized for specific applications including remote monitoring of water, sanitation, energy, infrastructure solutions or other applications. Remote monitoring via distributed in-situ sensors provides evidence to help inform the sector and public on the impacts of aid projects, and the on-going challenges.

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.
