Programs: Remote temperature monitoring of vaccines: we continued our project to use mobile phones to monitor the temperature inside of refrigerators and cold storage facilities, which are used to store vaccines and other temperature-sensitive medications. The transportation, storage, and distribution infrastructure that keeps many vaccines and other temperature sensitive medications at controlled temperatures called the cold chain is unreliable in many developing countries. The last mile of the cold chain, which includes rural clinics and delivery by foot as a health worker travels from one village to the next, is particularly vulnerable, marked by unreliable power and generator fuel tanks that run dry. If the cold chain is not maintained from the manufacturer to the location where vaccines are [continued on schedule o]

air pollution and clean cookstove monitoring: we have continued to develop our low-cost, cellphone-based black carbon sensor, which functions as an alternative to traditional, highly expensive measuring instruments. We have deployed our air pollution sensor in india in connection with a clean cookstove distribution project sponsored in part by the united nations environment programme as well as in service of a scientific study of cookstove adoption. These deployments have helped test our system's ability to measure the amount of soot that is generated by both traditional cooking fires and clean-burning stoves. With these measurement technologies, we are developing a system that can collect data about airborne emissions and help verify the amount of carbon emissions saved by switching to cleaner burning technologies.

other program services:programs supported by the organization all utilize mobile sensing technology to monitor and develop data for various activities, environments, and/or communities.
