Cookstove OverviewTechnical InfoCase Study

SWEETSense AIR provides environmental air quality monitoring in domestic, industrial, outdoor, and remote environments. This technology is competitive with existing energy efficiency and air quality monitors by offering a single package for multiple parameters, a lower cost, and simpler installation with no external power or data interfaces required. For many domestic applications, the SWEETSense™ may be placed in buildings with existing Wi-Fi connectivity, thereby further eliminating the cost of the cellular data requirement.

This technology has also been demonstrated in global development applications through the monitoring of high efficiency cookstoves installed in developing communities. While technologies exist to monitor stove use and emissions, the processes currently used rely on in-person visits, while current comparison studies such as the Shell Water Boiling test rely on controlled environments and manual weighing of fuel.

In this embodiment, the SWEETSense package includes thermocouples and CO/CO2 sensors to derive usage and stove emissions data, and relay the data remotely to partners and around the world.

SWEETSense AIR includes high temperature thermocouples, carbon monoxide and carbon dioxide sensors designed to monitor frequency of use, thermal efficiency, and emissions in a variety of applications including pollution sources, indoor air quality, and combustion efficiency.

SWEETSense AIR can also be customized, on request, with a variety of other gas emission sensors.

Carbon Monoxide
Carbon Dioxide

low power
Sensor based triggered event logging
battery level reporting
wifi or cellular network reporting
cloud-based processing
remote auto calibration

SWEETSense Air is being used by the London School of Hygiene and Tropical Medicine to compare how households report using improved cookstoves versus data provided by the sensor (embedded in the cookstove). Data suggests that even with use of improved cookstoves, households may use additional stoves for cooking. While the use of improved cookstoves results in reduced carbon emissions and particulate matter, the environmental and health benefits associated with the use of cookstoves may be overstated, due to the use of non-improved sources of cooking as well.
