Indoor air pollution is a global health concern, causing health hazards to people who are exposed to the pollutants which are released by burning biomass. In rural areas most people use traditional biomass cook-stoves which release carbon-mono-oxide and other poisonous pollutants into the air as a result of incomplete combustion of solid fuels. Accurately determining the usage of stove is important in assessing the exposure to pollutants. The temperature data-logger system embedded in the cook-stoves is one of the recent methods used to monitor the usage of cook-stoves. This method of monitoring the usage of cook-stoves can be used as an alternative to survey methods and questionnaires which rely mainly on householder’s memory, and are subjected to bias. The data-logger mainly measures the temperature of the cook-stove changes over a period of time, and also the duration of the usage of stove, which are then stored in the memory of the data logger. As a result, the temperature profile of the cook-stove can be determined. The data can be retrieved at any point of time and at any location from the temperature data-logger through global system for mobile (GSM) technology. This information can be used for the analysis of the stove utilization patterns by the householders. The major advantage of the proposed data-logger seems to be a precise and unbiased method of assessing the stove usage, and also it provides statistically reliable information with smaller sample sizes than surveys. © Research India Publications.
